Intel X99 Motherboard Goes Up in Smoke For Reasons Unknown

This morning I woke up bright and early to benchmark some DDR4 memory kits and found myself waking up not to Folgers in your cup, but the smell of burnt electrical after loading the XMP profiles on a memory kit and restarting the system. Let me tell you what happened, the best I can.

ASUS X99 Deluxe

On Friday I spent the day wrapping up the benchmarks on the Kingston HyperX Predator DDR4 16GB (4x4GB) 3000MHz quad-channel memory kit (part number HX430C15PBK4/16) that runs at 1.5V. This morning I wanted to get another kit of DDR4 memory tested, so the system was powered down, the CMOS was reset and a G.Skill 16GB (4x4GB) 3000MHz memory kit (F4-3000C15Q-16GRR) was installed and powered up the system.  It posted fine, so I went into the UEFI and set it to run at the only XMP profile on the kit. The UEFI changes were saved and the system restarted. It was during the next seconds that both the board and the processor would be killed off in a rather unspectacular death. The system came up, hung for a very short time and then powered off with a audible click of the Corsair AX860i power supply. If you’ve ever heard the loud click of the Over Current Protection (OCP) shutting down the PSU you know exactly what click I heard. Now when I press power button on the motherboard the system clicks after being on for a split second.  I unplugged all the cables on the power supply and did the built-in self-check and it passed with flying colors. I swapped out the PSU with a backup Corsair AX860i and the same click was to be heard. After clearing the CMOS, removing the memory, SSD and video card the system still wouldn’t post. At that point in time I switched to a non-digital power supply (Corsair AX1200) and it did the same thing although this time the OCP took a little longer to kick in. There was some audible crackling noises, followed by some smoke near the CPU VRM heatsink. So, the heart shattering smell of burnt electronics filled the room and I knew my day wasn’t going to be a good one.

ASUS X99 Deluxe Motherboard Burned

I removed the board from the test bench and started to do a visual inspection and couldn’t see anything wrong with any of the components on the front or back of the board. I know where the smoke came from, so I removed the VRM heatsink and the burnt electrical smell got stronger. There was some discoloration new to where one of the mosfets sits on the thermal pad, so clearly it was a failure of CPU voltage regulation system and one of the eight 60 Amp phases (Dr. MOS IOR 3550M mosfets) has appeared to fail.

It isn’t burnt badly at all, but you can some of the signs of an electrical failure on the second power phase from the bottom.

ASUS X99 Deluxe power phases

Looking at the board we can see that the failed component in question is part of the PQ1004, which is part of the VCCIN or basically the processor input voltage. Crap! On these Haswell-E processors, Intel has moved the voltage regulation on-CPU as part of the new Fully Integrated Voltage Regulator (FIVR). Previously there were five separate input voltages the motherboard handled: Vcore, Vgpu, VCCSA, VCCIO, and the PLL. On Intel Haswell-E processors all five internal power rails are pulled from the single VCCIN and the components on ours just had a nuclear meltdown.

ASUS X99 Deluxe Power Phase Melted

You can tell things got pretty hot as there were actually solder balls where they weren’t supped to be!

Our worst fears were confirmed when we pulled out our backup ASUS X99 Deluxe motherboard and put the original Intel Core-i7-5960X processor in and the system wouldn’t post. The boards debug display showed Q-Code 00, which is a bad sign. We tossed in our backup Intel Core i7-5960X processor and the system booted up just fine and we are off and able to benchmark again. The bad news is that I managed to kill an ASUS X99 Deluxe motherboard ($398.99 shipped) and an Intel Core i7-5960X processor ($1049.99 Shipped) after using it for less than two weeks, which is a bit unusual and why I am sharing information about this failure to the readers of Legit Reviews. It is not an everyday occurrence where $1450 in hardware gets put out to pasture.

LR isn’t the only site that has had a board go up in smoke as Michael Larabel over at Phoronix had an X99 board go up in smoke as well. He was not using the same brand of motherboard or power supply model, but to see X99 boards failing this early in the game is alarming.

I’ve been in contact with ASUS, Intel, Corsair and Kingston and no one is exactly sure what happened to our system. Was running 1.50V on the DDR4 memory too much? Is there something wrong with the VRM design or did we have a bad component on our motherboard? Was the power supply faulty? We aren’t sure, but we are going to be overnighting this board back to ASUS Taiwan on Monday (9/8/2014) and we have arranged for Corsair to put our PSU on their scopes and test equipment to make sure it is working properly.

We’ll let you know what happens if we find anything out in the weeks ahead!


Update 9/9/2014 – ASUS has received the X99 Deluxe motherboard that failed along with the power supply that was in the unit at the time of the failure. An ASUS employee will be taking the PSU to Corsair for testing on 9/10/2014. The board will be looked at here in the US and then will be shipped to ASUS HQ in Taiwan. In the meantime we have two ASUS X99 Deluxe motherboards being used by staff members that are still up and working properly and we have been told by ASUS that they have replicated out exact system and that they tested it overnight and haven’t experienced any failures. We’ll keep you updated and will post the actual Chroma test results from the PSU once we get them from Corsair. It was also learned in the past 24 hours that the ‘high’ DDR4 voltage (1.35 to 1.5V) that we were using on the board shouldn’t have caused any issues since the memory controller in Haswell-E can actually support DDR3 and DDR4, although only DDR4 is being implemented. DDR3 memory kits run at 1.5V, so that almost eliminates that from being the issue. The good thing about posting publicly about this failure is that all the companies involved are taking this seriously and are working overtime to ensure there isn’t an issue somewhere. We are really glad about that as we have recommended the board, processor and power supply and want to ensure that the platform works if our readers purchase the parts based on our recommendations.


Update 9/11/2014 – ASUS HQ in Taiwan has the motherboard and is looking at it now. ASUS and Corsair were unable to get the power supply tested on Tuesday and scheduled a time with Corsair to get the power supply on the Chroma tester on Friday 9/12/2014. This was the earliest that the Chroma tester was available for use during business hours.

Corsair Chroma PSU Tester

Update 9/13/2014 – Corsair along with ASUS tested the pair of AX860i power supply that Legit Reviews was using on the test bench at the time of failure on Friday the 12th. Both power supplies passed the initial Chroma test passes, but we learned something that we previously did not know.  When the Corsair AXi series of power supplies came out in 2012 they featured a single rail design. Corsair switched to a multiple rail design for the power supply series in 2013 (previously unknown to us). This is obviously a significant difference in the design of the power supply. We also learned that the earlier single rail power supplies did not have OCP enabled by default. One would have to install the Corsair Link Software package and manually set the OCP limits manually for that to function on the earlier models. We were not using the Corsair Link Software on the test bench, so therefore our power supply could have 90A or more potentially running down the rail. This might have exacerbated the damage to the CPU’s VR circuit if there was a bad component or solder ball joint present.

scanWe looked around at Newegg, Amazon, Scan and other major online retailers and have the Corsair AX860i as having a single +12V rail. Heck, even has it listed as having a single rail! Hopefully now that this has come to light the folks at Corsair can update their own site and get retailers to properly list the specifications of this PSU in the listings.

ASUS is still working with the failed board and is going to be replicated our setup with the power supplies in Taiwan. Yes, these two power supplies have now been shipped to Taiwan where ASUS HQ will be able to test our first revision AX860i Power Supplies as the ones they were testing with this past week trying to replicate our system without failure was done using the new post-2013 power supplies. The exact cause of the fault is not known, but much is being learned by everyone and most of it is valuable information that will help the community. We’ll report back with more once ASUS is ready to give us an update that is ready for public consumption. That will happen after additional testing is done on the board over the days ahead.

Update 9/16/2014 –  We are still working with Corsair to find out more on the firmware update that was done on their power supplies back in 2013. We have asked for dates and power supply lot numbers, so users can find out if they have one of the original ‘old’ AXi series power supplies that has no OCP by default. We also pointed out to Corsair that there is no mention of this in the instruction manual and that many users might not be aware that their flagship PSU has features that aren’t enabled unless they do so manually. From the sounds of it Corsair just updated the firmware and went to a multi-rail configuration. We’ve talked to several people about this issue and it was unclear if there was a hardware change and that is still being looked into. The bad news is that the firmware is not end-user upgradable. We have asked Corsair what if anything current customers can do since the firmware can’t be upgraded in the field. If you have an AXi series power supply we highly suggest downloading the Corsair Link software and programming the OCP setting.

Kingston Technology contacted us today and informed us that they will be lowering the voltages on the pre-production DDR4 memory kits that were sent out at 1.5V to 1.35V when they are shipped out to consumers. Kingston never shipped any DDR4 memory kits at 1.5V and won’t be. It doesn’t appear that the memory running at 1.5V had anything to do with our failure, but ASUS is still testing. We haven’t heard from ASUS in the past 48 hours and last we heard they were still looking into things in Taiwan now that our ‘old’ power supplies without OCP have arrived. ASUS said they will be giving us an official statement about the failure when the research is completed and we hope that will be sometime soon.

Update 9/17/2014 – Replacement ASUS X99 Deluxe motherboard was delivered (11 days from point of failure to replacement board being delivered).

Update 9/18/2014 – Corsair has gotten back to us with some answers to some questions that we asked earlier this week. It turns out Corsair shipped AX760i/AX860i/AX1200i power supplies for about four months before they changed the firmware on them without notice. The firmware is not field upgradeable and Corsair will not be offering exchanges for anyone with an ‘older’ model that wants to swap out a PSU for one with the latest firmware on it. Corsair also said that by the motherboard makers [ASUS] own admission, the X99 Deluxe motherboard was the root cause for the failures.  Corsair also said this which we will directly quote: “Would an OCP-defaulted AXi or a competitor OCP-enabled PSU have save the CPU? We’re skeptical, but maybe.” So, right now it looks like the board had a failure and then when the system was restarted the PSU without OCP may or may not have taken out the CPU through the boards failed VR circuit. We are still waiting on ASUS to give us an official statement as to what happened to the board and were told that a typhoon in the region this week has slowed things down. In the meantime here are some answers to a Q&A that we gave Corsair that you can take a look at.

– When did Corsair change the firmware on the AXi series of power supplies?

AX760i/860i implementation date 3/15/2013  Lot#:13119560

AX1200i implementation date 3/8/2013 Lot# Lot#:13099520

Corsair shipped the AX760i/AX860i/AX1200i for about four months before they changed the firmware on them. If you bought one of these models when they first came out you likely have one with old firmware. The Corsair AX860i first was made available for sale with Amazon on November 1st, 2012, so just a heads up to early adopters.

– Can you please highlight what all changes with the new firmware?

PSU set to multi-rail (which by definition is OCP).

– So, you went from a default configuration of one +12V rail with no OCP to a virtual multi-rail setup with OCP enabled by default?


– Why was this change not made public?

We saw no need for an announcement. The PSU design and its features stayed the same and this isn’t a design fault.

– Can end users with the original PSU design update their firmware at home?



– How can an end user know what firmware is on his/her PSU? (Can users identify by the serial number what PSU they have? )

By the serial number. The first four digits are the date code. The first two digits are the year and then the next two numbers are the week of the year that the power supply were produced. The image above shows a Corsair AX860i Power Supply with serial number 1249954 that was made the 49th week of 2012 and would be running the original firmware.

AX760i/860i implementation date 3/15/2013  – First Lot number was: 13119560

AX1200i implementation date 3/8/2013 – First Lot number was: 13099520

– If users cannot upgrade the firmware at home, can users exchange their PSU for a model with OCP enabled by default?


– How many Amps does the OCP default to on the AXi series. I heard it is different for each PSU?

By default, 40A. This is configurable.

– I was told that Intel Haswell-E processors are using up to 47A when overclocked to 4.4GHz and that it exceeds the OCP on some PSUs. Some motherboard makers are telling us to stay away from certain PSU’s. What are your thoughts on this?

When you have a PSU with multiple +12V rails, OCP can easily trip if the CPU is overclocked and running over load.  This is why Corsair PSUs with Link Digital allow the user to disable OCP and why all other Corsair PSUs feature a single +12V rail.

– ASUS designed the VR circuit on their X99 platform with 60A components. Corsair came out with the AXi series in 2012 with an adjustable OCP that was off by default. Was Corsair foreseeing a situation in the future where end users could customize the OCP setting depending on what motherboard they were using?

Initially, Corsair was simply following our existing trend of providing power supplies with a single +12V rail.   Since OCP is most beneficial during the initial build stage of putting together a PC, it made sense for the PSU to have the OCP on by default and therefore we decided to make the change.

Update 9/22/2014 –  ASUS informed Legit Reviews that they will need 2-5 more days before releasing an official statement on the failure.

Update 10/01/2014 –  ASUS is needing more time to discuss what they have found out with Corsair before making a public statement. We have been told that it will be another day or two until they will be able to say something. It sounds like some issues have been found during testing and the results are being looked into by both companies.


Update 10/6/2014 – The two replacement Corsair AX860i power supplies were just received today, which just happens to be one month to the day from the platform failure.  ASUS informed us this morning that Corsair is requesting more information on their test setup and that needed more time again. We are hopeful we’ll get an answer soon, but it appears that ASUS and Corsair are having issues with what the test data relates to with the failure. It sounds like multiple things went wrong and of course no company wants to take more blame than they have to.

Update 10/9/2014 – Just received word from ASUS that the Corsair engineering group received the additional information that they wanted about the testing ASUS did and now ASUS is waiting to hear back. If ASUS gets an answer tomorrow they are hopeful that they will be able to provide a detailed response on the failure or failures that they believed happened to out platform on Monday (10-13-2009).

Update 10/13/2014 – We talked with ASUS and Corsair over the past several days and there was mention of needing a few more weeks to figure things out. It appears that Corsair is disagreeing with the ASUS findings about the power supply we were using and the testing of it at ASUS HQ. Legit Reviews has been kept in the dark for the past several weeks and can’t really do anything other than wait. Right now it appears that something might have been off with our power supply. Corsair gave us the Chroma test reports from their testing, but we have not been given anything by ASUS. We don’t know what was seen in the latest round of testing, but we do know that ASUS tested the PSU on a system and not just a PSU test machine. What did they find out that Corsair disagrees with? It feels like some people are trying to drag this out and hope it blows over. Is it working? We are still seeking answers from both ASUS and Corsair.

Update 10/22/2014 – No update from ASUS USA or Taiwan, but we did find out that someone at ASUS Singapore posted up a comment at Hardwarezone about our failure. ASUS@SG stated that our board failed due to a faulty pre-production BIOS/UEFI. They claim that the bug was discovered by Intel and the fix was done by ASUS before the first official UEFI release.  Now Intel is being blamed? The same ASUS eCustomer Service Center employee then followed that post up with a post stating that Intel could have had a bad batch of Intel Haswell-E processors. Very interesting. Legit Reviews still is still waiting on our official answer from Taiwan.  It is disappointing to see possible answers to our issues on other sites as ASUS hasn’t said anything about a bad BIOS/UEFI to us since this whole ordeal began.


Update 10/22/2014 Part 2 – ASUS USA told us they aren’t sure why ASUS@SG would post such comments and told us that is not the primary reason for our board failure. They didn’t deny having a UEFI/BIOS bug though, so this is starting to get interesting. Could we be getting close to finding out why our ASUS X99 Deluxe motherboard failed? Hopefully ASUS will give us something since they have representatives telling people what happened on forums, but then the ASUS employees we are working with are telling us that is not the truth. Ugh!

Update 10/23/2014 – ASUS released UEFI 1004 for the ASUS X99 Deluxe today and we have been told that this update includes an EC (Embedded Controller) Firmware update that fixes something discovered by our board failing here at Legit Reviews. We don’t have the official response from ASUS yet, but Legit Reviews highly suggests that all ASUS X99 Deluxe owners update to UEFI build 1004 due to the fixes implemented in it for the way the board power is being handled. The build date on this UEFI is 10/16/2014, so it has been around for a week before it was made public. ASUS also reprogramed the memory tables after receiving new microcode from Intel. That made a world of a difference on our board when running memory kits beyond 3000MHz with 1T Command Rates. Here is a list of the key changes:

ASUS X99-DELUXE BIOS 1004 Change Log:
1. Update EC FW
2. Fix crash free issue
3. Fix Xonar card compatibility issue
4. Revise Thunderbolt memory resource
5. Enhance Xeon CPU compatibility
6. Rebuild SteamOS boot option

We have been told to expect the final answer on our failure from ASUS on Friday.



Update 10/24/2014 – Legit Reviews was just sent the failure analysis response on our ASUS X99-Deluxe Motherboard.  You can read it in its entirety below:

Hi Nate,

We have determined the primary cause of failure for the pre-production ASUS X99 Deluxe you were testing on September 6, 2014 along with a secondary cause gathered during the investigation phase. Our initial analysis of the VRM Phase-4 MOSFET/Driver package failure is a bad solder point that was also present at the VRM Phase-3 location resulting in the failure you described along with the presence of solder balls.  Additional analyses lead us to believe this was the secondary cause for the failure described.

After extensive testing and collaboration with leading power supply manufacturers and our VRM supplier (International Rectifier) it was determined that the new VRM design on the X99 Deluxe board needs a firmware update to balance start-up and shutdown power loads and sequencing across the MOSFET/Driver packages.   We determined that higher loads were placed on the VRM Phase-4 package when the processor was drawing less than 70 amps of current during start-up and shutdown sequences based on the original firmware.  This along with some older power supply OCP/Shutdown anomalies results in a bad component combination that randomly (very) leads to a VCCIN spike and power surge on the VRM Phase-4 MOSFET/Driver package that could cause component failures.  We still have not replicated this failure in our test labs after thousands of hours of testing across a significant number of component combinations. However, we believe this was the primary cause for the initial board shutdown and the solder point issues exacerbated the subsequent component failures in the manner you outlined when using the secondary power supply.  The good news is that we have a solution to this potential issue.

We are releasing a new EFI (build 1004) today that addresses this issue by balancing start-up and shutdown power loads across all VRM Phases when the processor is drawing less than 50 amps.  This will greatly mitigate the chance of a VCCIN spike or power surge in rare instances based on extensive testing.   Our new balancing/sequencing rules will decrease overall power efficiency results by a few percent based on processor loading under 50 amps but otherwise the board’s overall performance will not change.  In addition to the new power rules, EFI release 1004 features a host of performance improvements with significant improvements in the area of memory overclocking using the 100 strap at speeds up to and past DDR4-3300.

We highly recommend that all users of the ASUS X99 Deluxe board download and install EFI 1004.  This EFI is available from our support site starting today – X99-Deluxe EFI 1004. Please follow the proper instructions for updating your EFI.  The update guidelines are available at ASUS USB BIOS Flashback Guide or follow the instructions in the user manual when utilizing USB BIOS Flashback or EZ Flash 2.

ASUS is firmly committed to supporting our class leading X99 Deluxe motherboard that features unmatched performance and options like our patent-pending OC Socket, 5-way Optimization for one click overclocking and fan control, 3×3 802.11ac, Fan Expert 3 and Crystal Sound 2.


When our ASUS X99-Deluxe motherboard failed back in September during a system restart things just didn’t add up. We’ve spent tens of thousands of hours testing hardware components over the past 12 years and we posted up our findings in the event that others in the enthusiast community might have similar issues. When this post went online it got mixed feedback from many in the community. ASUS asking us to take it down until the cause was figured out was expected, but we were shocked that other hardware reviewers in the article posted negative comments (still shown below) about how we were doing ASUS an injustice. Unfortunately, we weren’t the only people in the world to have an ASUS X99-Deluxe motherboard fail and almost all the failures reported online were by folks that also were using Corsair AX/AXi power supplies. Something was obviously going wrong with that combination and no one could figure out what was causing the failures at first.

ASUS went out and bought Corsair AX860i power supplies to try to replicate our problem, but it was later discovered that the power supplies being sold today were different than the ones we were using. It turns out Corsair changed the firmware on their power supplies and the change was rather significant. The firmware changed the default configuration of the power supplies in this series from one +12V rail with no OCP to a virtual multi-rail setup with OCP enabled by default. This obviously didn’t cause the board to fail, the bad solder point was, but it could have contributed to the processor blowing up after the solder failure as OCP wasn’t enabled on our PSU.

Our failure caused ASUS to gather power supply manufacturers and their VRM supplier (Iternational Rectifier) and they looked at the new VRM design on the X99 Deluxe motherboard for weeks. They went through the design from top to bottom and figured out that they did indeed need to balance start-up sequences as the loads weren’t even. Guess what VRM Phase has the highest load? Yes, the one that failed on our board during a shut-down/start-up sequence. It appears that our Corsair AX860i power supply was one of the power supplies that had these anomalies and between the PSU design and the original VRM balancing/sequencing on the ASUS X99 Deluxe motherboard were just right to cause the failure we saw in the field. ASUS has released UEFI 1004 that changed the way the balancing/sequencing is done on the ASUS X99 Deluxe motherboard. They believe this will prevent any failure from happening to others and we are excited and happy that ASUS was able to come up with a fix. ASUS has proven that they will go the distance to make sure that their boards are stable. We are also glad that we published this article. We learned a great deal by doing so and it brought a situation to light that might not have been otherwise.

To summarize:

  1. ASUS X99-Deluxe Motherboard owners should immediately update to UEFI 1004. (No other ASUS Intel X99 board is impacted since the ASUS X99 Deluxe had a unique VRM design and firmware setup)
  2. Corsair AXi Power Supply Users Should Use OC Link Software to enable OCP on their PSU if it was made before March 15th, 2013.
  3. The ASUS X99-Deluxe Motherboard is safe to buy. We got another ASUS X99-Deluxe board up and running the day this one failed and it has not failed. We had some DDR4 stability issues with memory kits running 3200MHz, but ASUS fixed that with new memory tables in UEFI 1004. This board is one of the most thoroughly looked at Intel X99 boards on the market today and that should bring comfort to many. We know many of our readers were waiting on this situation to end before buying a $392 board and we don’t blame you.

This concludes our ongoing coverage of our ASUS X99 Deluxe motherboard failure. We’d like to thank our readers that stood up behind us on day one and laugh at those that lashed out for posting this article.  Legit Reviews was created to bring the truth out and to make the enthusiast community better. This article is an example of what drives Legit Reviews and we hope our readers appreciate our vision. Also we’d like to thank the many companies that were involved in solving this issue.  You could have left us in the dark, but you didn’t. You trusted our information and spent time and money to come up with a solution to the issue. You don’t get support or trust like that with all companies, but ASUS, Corsair and Intel are industry leaders for a reason.

  • I Don’t agree with you, I read a lot about Intel X99 Motherboard and everyone says that s the most powerful Motherboard.

  • tomasss123

    Hello, I’m from Argentina, I had and I have a plate x99 asus strix gaming that happened exactly the same. the computer turned itself off, as it did not light normally I turned it on from the power onboard button. and there I heard how the second mosfet was melting (from left to right). I made a hole in the motherboard. I made a formal complaint to ASUS and they offered me the user manual! ¡¡¡¡¡¡¡¡¡¡¡¡¡¡¡.
    I tried to fix it on my own and when I approve it, code 00 appears.
    I will surely burn the i7-5820k. I want to clarify that I have a 1000w source of thermaltake (SMART M1000W), check it and its voltages are normal. so I fail some of the VRM phases of the motherboard. It gives me a lot of anger because I have other cheaper plates of asus with generic sources and nothing happened. I will never buy x99 plates again. what will be of the experience is learned. thanks because what they published helped me understand what happened to me …

    Fried 2 i7-6750k. With this board. I hope the deluxe ii is better.

    I have a similar issue right now actually with my Asus ROG Strix X99 Gaming. Came home after work and pc running idle in windows, so when I got home the PC was dead. Tried to start it up and booted up for like half a second, didnt see any faulty codes so automaticly thought it was my old ass PSU, ordered a new one, same issue. Hit Mem OK button. Same issue but now the CPU issue led flashed while trying to start. Same click btw in both PSUs, first was a 650w Corsair and new one EVGA 850w. So I sent the whole thing with CPU and RAM and MB back to the guys I ordered it from. Cause of the faulty code I thought the CPU was bust, but they have apparently done an RMA on the MB. Still waiting on my parts though but they have only done an RMA on the Motherboard so think its the same thing actually. And I had the latest Bios installed on mine, it had worked fine for around 4 months and suddenly it dies idle in Windows. Makes no sense to me.

    • Shervin Babavand

      Dude!! I’ve the exact same problem Just happend today!. I’ve got a Corsair 1200AXi, and The X99 Asus Deluxe II motherboard. You are not alone, Had my computer overnight on idle, dead in the morning, as soon as I pressed the power button, the computer turns on for just a sec then shuts itself off.

      I did a temporary fix by disabling the OCP protection on the Corsair PSU, I will replace both motherboard and PSU later on.

      Corsair and Asus has been awful in both hardware and software support. I will avoid these brands in the future.

      • Balubish J Wiking

        Damn that is weird. Something wrong with the X99 platform or just Asus? Also how do you disable OCP? I had the same problem after I put in my EVGA PSU…. Shit happened to me last week.

        • Shervin Babavand

          Dude sorry for the late reply.

          A few days later, now my setup has now completely died. I’ve made a new thread at Asus forum, and video, check it out.

          I suspect that the X99 boards are killing the CPU’s

        • Balubish J Wiking

          Well my CPU was fine atleast what the company said I bought it from. They tested my CPU and RAM in another system and said it worked and sent the board to Asus for RMA last week. Yeah just watched your video, we dont have the same problem. Here you have how mine behaved. It dies within less than a second.

      • Balubish J Wiking

        Well i couldnt do a temporary solution sadly cause I had the same problem with another PSU from EVGA. 🙁

          Yeah I don’t think you can do it my way, The Corsair PSU is controlled by the Corsair Link software (which by the way is crap) from there I can control the PSU’s OCP settings.

          Try on more thing. There is a Clear CMOS button on your motherboard, almost same as mine, Try pressing it when the system shuts down in 1 sec.

          Also update to latest BIOS

        • Balubish J Wiking

          It had the latest update. It worked for several months. And i tried all things you can. Its sent back to Asus for RMA by the company I bought the parts from.

      • Balubish J Wiking

        And I got a mail yesterday that the MB is actually bust, so its going to Asus now. Im kinda worried though if this is a X99 problem or an Asus problem and whats causing it.

    • Cato

      same problem her, asus rog strix x99, corsair AXi 860. fried cpu. company I bought the mobo from have tested the asus board for 32 hours, and say it’s okey. I don’t want to put another cpu in to the same mobo.

      • Balubish J Wiking

        Yeah im not sure whats going on, several ppl seems to have problem with X99 Asus boards. They tested my stuff and said the CPU was ok though cause they tested it in other systems, so last week they sent it to Asus USA for RMA. Gone 3 weeks already. I wonder if its Corsair PSU’s or the X99 MBs that are the problem here.

        • Cato

          as long I get new stuff from asus or intel. but it’s frustrating. I want to send everything in return if it happens again. and go for a another setup, maybe test out this new amd stuff.
          how is it with this intel cpu’s? I bought it in December, the build was finally finished in January. worked for one month. I haven’t registered the Intel cpu extra insurance. but do I need it?

          sorry in advance for bad English or the way I write. 😋

        • Cato

          have we heard much about other mb died with corsair power supply?

        • Eagleizer

          My X99 Deluxe died overnight together with my FSP 1200w PSU.
          No crazy OC. Form default to 4.6 with the 5 step optim.
          It had been running “fine” for a year or so with a GTX690.
          In August, I installed 2 GTX 1080 FTW, and short after I got a power
          surge warning with safety shutdown.

          I contacted FSP, who told me I was going to be contacted by support
          in Thailand. I never heard form support, and I was busy getting both
          my EVGA 1080s replaced bc. of serious heating issue. I had to RMA one at a time, and time went by without any new warnings about power surge.

          So when my PC died in November, I contacted FSP again and told them I never heard anything from Thai support. “Have you checked your
          spam box?” WTF! I told them YES and have never heard from them
          since. I have written to them many times, but no answer.

          Bought CM 1200w Platinum, and as it turns out, the X99 have a
          shortcut on the 8pin power connection, making the PSU shut down.
          I have no warranty on this MB as it was a replacement for a ASUS RIVE
          that blew up and killed my QX9650. 🙁

          Bought a new Deluxe II today, and it will not post, and is showing
          Code 00, but at least no shortcut on the 8 pin. Yeay! lol
          I checked the pins before I installed the CPU, and noticed that one
          pin was dark and not at all shiny as the rest. I fear that my 5960x is
          dead, but still have a tiny hope that it is the dark pin that is causing
          the issue.

          I have struggled with getting money to get my PC up and running since
          early November 2016, as FSP refuses to answer my mails so I at least
          can get some money for the broken PSU. The PSU have 5 years
          warranty, and should also cover damages up to 5mill dollar as it say
          on the box, but that does not help much when they are ignoring me.

          I am taking back the Deluxe II tomorrow and bring all my suspected
          broken parts to have them tested. I am seriously considering a different
          brand, but I guess I will have to find out if I still have a CPU first…

        • Cato

          I did get my mb back from testing and that they said it was OK. my cpu died, and mb debugger said 00. I’m getting a new cpu tomorrow, so I’m not sure if I want to start this up as it is, I have not been in contact with corsair. but wondering if that’s the safest way to go before starting this up again.

        • Balubish J Wiking

          Well I dont want to wait 2 months or so for new stuff all the time. And I think when you done RMA on one thing you wont get another one I think, im not 100% sure how it works. But I have never had a problem like this under my 20 years or so PC hardware usage. If it happens again I will try to get a return as you said and maybe get AMD Ryzen for rendering purposes but dont think I can after so long time, maybe on the MB if it happens again. If that happens It hink I will buy another brand. I have never had problems with Asus before but it seems alot of ppl have problems with the X99 platform, or Corsair PSU’s. I bought an EVGA PSU now so if it keeps running with that I will know for sure its Corsairs PSU’s that make this problem. I built mine in November and have worked fine since and now it died while idle in Windows which is really weird, I can understand stress work. Im not sure on ur CPU and the insurance thing I havent registered mine either I think, but should work better than mine cause its more expensive. Still this is the first time buying high end platform and its also the first time I get problems which pisses me off really. Should be even better quality for the $1200 or so I payed for it. No worries on the english, im not native speaking English either 🙂 btw here is how my PC acted after it happened.

        • Cato

          exactly the same problem here, but I’ve tried another psu and it’s the same problem (starts for 1sec and dies) and mb is okey says the company I sendt it back to for testing. so I think cpu is fried and sending that in to day. but if I get a new cpu, I want to try to prevent this to happen again. I’ve used a simple apc, but any idea on usage of apc’s or ups? I’m just trying to think a way to minimize the risk of it to happen again.

        • Cato

          I forgot, after the mb came back after testing. the mb, all led’s and fans starts up now. but the debugger displays 00. no signal.

        • Cato

          testes the computer now and it’s back to starting only one sec and dies.

        • Balubish J Wiking

          Did you check the fail codes? Cause mine showed CPU, but the company sent back the CPU and Ram cause they said that were fine on mine and tested on other systems. Did you also get CPU fail code led flashing? When it comes to UPS and APC I dont even know what it is, I dont think that would be a problem they only give you power if you have a power outtage right?

        • Cato

          I did get one red led light before æ sendt in the mb. but not now. all is starting up but no signal to monitor, and I think 00 on the debugger stands for no signal from cpu.

        • airedad

          Not entirely correct. When my X99 Delixe (not the II) died 2 months in, they sent a replacement MB. But it was DOA, and I was able to RMA it and get yeat another one (which I didn’t trust and which looked like it had seen very hard service and then “cleaned up” (but only partially – there was even a fingerprint in some kind of grease on the back side of the MB). Sigh.

          Total downtime waiting for replacement MB that worked was 4 months. I’ve built over 150 systems (office, co-workers, friends, family) over the last 20+ years, and I have used only 2 Asus MB’s. The first failed in less than a week (that was about 20 years ago – I don’t feel like looking it up right noe) and I got the full runaround treatment. And I eventually ended up with a factory “factory repaired” MB instead of a new one like the one I paid for. Fast forward to the near-present. Same deal. This time it took 4 months. The first time it took 2. no wonder I’ve only used 2 ASUS MB’s in 2 decades. Well I’ll vote with my wallet: I won’t buy buying any more ASUS products as long as there is any other vendor around.

  • Anthill Beetle

    Amazing article! How sad it is buried so deep in Google… Wish I saw it before buying this motherboard and trying to use it in production :(((((

  • SlipperyNinja

    New victim here, my ASUS X99 Deluxe U3.1 has a serious problem overnight. Immediately after it’s latest BIOS update 3301 installed via USB, I hit F2 to enter BIOS after it restarts, something is not right, the XMP profile has changed to an extreme configuration of 3000mhz, initially it was on 2400mhz or 2666mhz. My Ram is only 2800mhz! So anyway I’m looking around in BIOS and out of nowhere, the PC switches off.

    OK maybe it crashed? Hit the power button, nope, nothing. The mobo QCode is on 00. There are no CPU/RAM error LED’s lit. So what’s the problem? Did everything, disocnnected the CPU power and the PC fans (not all) began spinning, but as soon as I reconnect CPU, PC will not start up. I am sure my X99 has partially died and taken the CPU with it!! I’ve had occasional reboots before (used for less than 1 year) but this has to be a BIOS fault? or something, this is no coincidence.

  • brokenticker

    Got a problem. I just found this review for the Asus X99 Deluxe from 2 years ago. Last May, I purchased a Asus X99 Deluxe/U3.1 from and had problems from the word go. Multiple error codes, and complete boot failures because the OCP kept tripping on my Thermaltake 1200 watt PSU. After 6 different RMA’s to Newegg, I switched gears, and put the Asus aside on my workbench and decided to try a Gigabyte G1 Gaming GA-X99-Gaming 5P (rev. 1.0). Exact same set of problems, errors and no booting. Now I had updated, the bios on all of the boards as I went along, to no avail. Nothing I did ever made a difference so I then tried an ASRock X99 WS, and on a whim also ordered a Thermaltake Toughpower Grand TPG-1200M 1200W ATX 12V. Finally I had some life in my computer. After I finished setting it up I started having issues with this board as well, but these are different. The core of the problem appears to be a problem with the hardware initialization, during startup. I usually have to do 2-5 power cycles to get everything running correctly. Failures include, but are not limited to, freezing during post, SSD boot failure, onboard Ethernet failure, partial sound card failure(The 3 line output will work but the optical SPDIF, and digital line output will not), system hang while loading Windows 10. Now even with the network and sound failures, if I load into Windows and check the devise manager, It will show the drivers installed and working properly, but the hardware does not fully function. The Control Panel for the sound card will not show the Digital or SPDIF options that the card has. Now I sent a email to ASRock, and what they sent back was, of course, the standard form response that I assume they send to everybody which included the suggestion, reload Windows 10 which is retarded because I’m writing this on the same computer right now.
    Now, all that having been said, a friend of mine asked me to build him a computer and to try to save him some money, and since I “happen” to have a $400 paperweight collecting dust on my work bench, I decided to give it one more try. I dropped in a Intel Core I7 5820k, updated the bios again with the latest bios update, added 1 stick of ram, video card, heat sink, and 2.5 inch HDD, and crossed my fingers. Nothing. All LED’s are good. Error code D6-No Console Output Devices are found es usually what I would get, but now when I would hit the power button, it would lite the LED’s. Complete boot failure. Thought about it for a couple of days and tried an older Thermaltake 1200 watt PSU to see what it might do if anything so I swapped the PSU’s out, plugged it in, hit the button and SNAP! Puff of smoke from the Mosfet heat sink right behind the input panel. Prolly from the exact same place that you describe in the review, except this is, at the original time of purchase, over a years “after” the review, and I’m not using a Corsair PSU. No clue if I smoked the CPU as I don’t have a way to test it, short of taking this computer apart, and I’m having enough problems with it everyday as it is. Having found this review now, are there any thoughts as to why Asus, and other manufactures haven’t fixed these production issues after all this time? I can RMA this board to Asus, but at the moment, I have ZERO faith I would get anything back that would be worth trying to use.

  • alan maddison

    I sadly had this issue very recently with an Asus Sabertooth X99 and a 5820K. I was enjoying it for a few days and then put a mild OC of 4.1Ghz at 1.100 CPU Voltage. A few days later during some gaming and recording the machine turned off never to be on again. I also heard the nasty *click* sound as I attempted to start the board back up. I used an EVGA 850W P2 which is one of the best 80+ Platinum PSU’s out there (Loved the JonnyGuru review, it’s what sold me on it). The difference was that mine died during use not on a restart or shutdown. THe only thing that told me my CPU was dead was a “PLED1” orange LED next to the CPU that literally is just there to indicate whether or not your CPU is functioning. I found a small thread on it on and was just sickened by this. I have to say, I probably will not use an Asus motherboard until they get there Quality Control issues figured out. I mean, I bought my system all of 2 weeks ago and this article is from 2 years ago….. Something is not right here…

  • Kai

    Mine just did the same thing! Very frustrating… It did a hang on boot-up and then when I turned it off and back on > Poof, Code 00 and CPU LED is on. This really sucks… I have an HX1000i


    I have run my 1680 V3 with the Asus X99 Deluxe, AsRock X99 Professional and Asus Rampage V Extreme. THe X99 Deluxe is just a piece of crap, It blows my mind how could asus release a motherboard that is so full of it. The Ramapge V Extreme is a fucking expensive motherboard with bad value, comes with nothing that can justify the price and is also prone to memory problems, just like as with the deluxe despiste using only QVL qualified memory. The Asrock X99 professional surprassed my expections as it is the most estable of the bunch but also the cheaper board. That’s the last time I spent my money with asus products. Their products cost premium but their support is CRAP. You heard me asus ? YOUR SUPPORT IS CRAP !!!

  • Davemn

    Hi, this problem may not be exclusive to corsair PSU. I had owned a x99-s for 5 months (July 2015-january 2016) and I experienced a similar problem. Using a OCZ ZS 750W and 5820k, my PSU died within 2 months of normal usage with my X-99S(no electrical burning, probably protection kicked in or internal fusing). I assumed it was a OCZ cheap PSU thing, so I went and bought an Antec HCP 1300.

    I plugged it in, everything works as normal. I’m using it normally until last week, then the same scenario happens again while I’m idling on desktop (electrical breaker triggers, PC suddenly dies and won’t boot). Paperclip test confirms the antec isnt functioning(could be in protected state, antec protection is different). I plug in a corsair RM1000 and I get exactly as you describe, a loud click a second after all fans initiate, and the PC turns off. My processor is still in one piece, and I’ve sent the board back to retailer for a refund after much troubleshooting (Asus RMA couldn’t log my product?). I hope my CPU is fine, all PSU I’ve used with it have OCP protection. I’m reaching out to antec support to help me get my HCP replaced.

    Maybe the first PSU was faulty and it damaged the board, causing a knock-on effect to my second PSU. but the way both PSU failed in the same manner in such a short time span, when im not running systems intensive applications is very strange. I was on latest BIOS versions at all times. It is nearly unheard of to have the HCP 1300 to fail in such a short time span(2-3 months, singular graphics card).

    • Davemn

      If its any help, my system specs were:

      i7 5820k @ 4200mhz (127.3 bclk, 33 core ratio)
      4x4GB GSkill Raw 2800mhz using XMP
      1x asus R9 290 reference design (singular fan)
      Asus xonar stx II
      Asus X99-S on latest BIOS
      6 140mm fans and a NZXT kraken X61(for power usage speculation)

      PSU’s used:
      OCZ ZS 750W (first fault while gaming, dead)
      Antec HCP-1300 (second fault while idling, possibly dead)
      Corsair RM1000 (testing, troubleshooting, functional)

    Is the X99 Deluxe still a nightmare? I have been thinking about buying one along with a 5960X.

  • Daniel Ng

    Thank you Legit Reviews.

    The reviews you guys do are beyond helping with shopping lists.

    It also keeps manufacturers on their toes with the product and honest when something fails. Corsair working with Asus on this problem alone is good enough. I am sure future mobo/psu releases will be greatly improved.

  • Crusher

    Well almost 12 months and my Asus X99 Deluxe with an 8 core 5960X running an AX1200i PSU has failed to POST and illuminating the CPU-LED on the mother-board indicating CPU failure. Lets see what the out come is tomorrow when the tech strip it down.

  • Ax0ne

    I had the exact same symptoms on my Asus X99-S. Pins are not bent or whatever, and I’m waiting for Asus to repair or send a new one. My PSU is Corsair HX750i and I honestly didn’t check with Corsair link if OCP was enabled. I hope that my beautiful 5820K is not dead 🙁
    I keep you in touch…

    • Ax0ne

      Update : My new motherboard was received 1.5 months later. Now I’m discovering that my CPU is also dead (not really surprised, having read this article). Starting Intel RMA now, let’s hope that it will be fast and without too many questions. Asus, I’m tired !

  • Onafets

    I know this is old, but – this just happened to me as well. I have an Asus x99 Saber and my PC just shut down and will not post or turn on if the CPU power is in. If I take out the 8 + 4 pin CPU power, the machines powers up but still does not post. Sounds like a Mobo issue?

    • solomonshv

      what PSU do you have?

      • Onafets

        I have a 5820 Haswell, and I found out what my problem was. I believe the pins on the mobo were bent, got a new mobo and all fixed 🙂

  • Nauman

    I was thinking of buying AX 1200i. After reading this article I was in doubt. Today i checked with the retailer here. The manufacturing year is 2014. Hopefully, this one would not have any such problems. Any thought.

  • Christian Verreault

    It’s a pity that your web site didn’t make such an extensive investigation regarding the UEFI BIOS Frozen Clock bug on almost all Z87 and Z97 based motherboards because we perhaps would finally know now who is the culprit in this story …

    • solomonshv

      for me it was the intel raid driver. once i uninstalled the intel storage drivers my computer started working fine. in any case, i don’t have my Asus Z87 “Hero” board anymore. i have an Asus X99 deluxe now.

  • Tyson Merten

    ASUS burned that 5960x by sending you a board with a beta BIOS then.

    I really hope you made them replace it.

  • airedad

    Not all of the failures involve a Corsair PS.

    I bought an X99-Deluxe from Amazon on 12/21/2014 along with an i7-5930 and 16 GB of Kingston HyperX Prditor DDR4-3000 and installed the system on 12/26. I IMMEDIATELY loaded the 0904 BIOS having seen BIOS problems with other MB’s over the years (I don’t have 10’s of thousand hours of testing experience, but I have built somewhere in the range of 250-300 systems for friends, family, charities, and co-workers over the last 25 years and my best estimate is that I probably have 2500-3000 hours of hw debugging experience).

    My new system ran Linux (Fedor fc21) for exactly 8 weeks, and due to workload I never got around even to trying to overclock. Then I powered down (“shutdown” – and the machine did a controlled shutdown and powered off). After that I moved the machine’s power cord to a new UPS (load balancing in my “lab”/home office) and rebooted.

    Even though the PS here is NOT a Corsair (it’s a humble, 3-year-old CoolerMaster with 650 watts and 3 19-amp 12v dc rails) when I booted the machine up, it hung somewhere between the POST and reaching the boot prompt, and after about 5 minutes I hit the reboot switch to start over.

    The machine was dead at that point and after a much-less-bearable (MY side sounded a lot like like “no, I don’t think the failure was cause by anything in windows since I don’t run windows…” or “I don’t see how the cause is could be the keyboard (Corsair K70) I’m using …”) series of exchanges with Asus I finally received a replacement board in about 2-1/2 weeks. Then of course I discovered that the CPU was also dead and I’m waiting now for my RMA from Intel so that I can replace it, too. (I couldn’t test it – I’ve been building multi-cpu AMD systems for 15+ years and this was my first intel machine since at least 1999 – so I had no machine to test it in and no friend foolhardy enough to let me put a potential “killer” cpu in HIS MB to test it.)

    So the problem is not confined to either the Corsair PS’s OR to single-rail 12v supplies with 50-90 amps of 12v DC on tap.

    At this point I’ve upgraded BIOS on the replacement board to the newest 1502 version and I am ordering a new, heavier power supply (that was a “suggestion” – not a “request” – from Intel). (The CoolerMaster bench- and load- tests as completely within specs BTW and it will go into another, older machine here to replace its PS).

    Nevertheless I’m still a bit worried since we already know that that the problem got right through the 0904 BIOS fix, AND it wasn’t stopped by the multi-rail PS.

    Honestly had I not read of (what sounds like) the same thing happening with MBs from other vendors, I’d put this MB on Ebay and let some other poor sap worry with it and buy something else.

    I do, however, wish I had seen this article BEFORE I bought this MB… So thank you for publishing it. And I’ll keep looking for more updates if and as they become available.

    Just had an X99-Pro fry this weekend playing BF4. Had lockup problems and thought it was the Asmedia controller driver until I figured it out that it was my antivirus software Avast. After uninstalling Avast and installing McAfee it was running great. 20 minutes into playing BF4 it suddenly shut off with no errors. Now it will spin the fan for a second and shut back off. Has lights on the board but no led numbers and never beeps. Clearing the CMOS changed nothing. I even removed all the expansion cards with no change. I sure hope the CPU isn’t fried:/ I was running the memory at 2800 and the CPU at 3800 so it wasn’t overclocked by much. I opened a ticket with ASUS so I guess I’m on the RMS pain train.
    Asus X99-PRO (running latest 1401 bios)
    EVGA GTX-980
    Intel i7-5930k
    G Skill 2800 DDR4 memory
    Corsair HX750i (running multi rail in link software)

    • Paul Mudd

      Update – Mar 30, 2015
      Asus Tech Support contacted me and told me to clear the CMOS and listen for beeps:/ I had already told them it was never getting to the point in the boot cycle to beep. I removed all the expansion cards and cleared
      the CMOS again but there was still no change. Lights are on the
      motherboard but no LED numbers or letters and the cpu fan would only
      spin for a half second then shut off. I cleared the CMOS for the
      fourth time then removed all memory sticks except for the number one
      slot. This time when it booted the fan spun a few seconds longer and
      appeared like it might actually boot up. As I was watching it red
      smoke started coming out from under the VRM heat sink and then sparks
      started shooting out from the same location over to the CPU socket. I
      immediately turned it off as the motherborad was now fried and I prayed
      it did not fry my other components. I got an RMA number and mailed it off to the Asus Service Center.

      Update – Apr 8, 2015
      Asus said it was my fault and the motherboard was damaged beyond repair then they sent me a bill for $320, that included $10 to return my damaged motherboard. So basically they won’t honor their warranty if the motherboard shows any signs of damage even if it was caused by their defective parts. I was livid. This motherboard was only two and a half months old. Asus tech support was absolutely horrible. I was getting confusing and inconsistent responses nearly every time I contacted them. This motherboard did not smoke or burn until I contacted tech support and followed their troubleshooting instructions. If this happens on my Sabertooth X79 the only thing I will do is clear the CMOS because I will be blamed if damage occurs from following the Asus techs troubleshooting advice.

      Update – Apr 10, 2015
      My experience with Asus was absolutely horrid. Out of desperation and realizing that Asus was not going to fix or replace my motherboard I contacted Amazon’s customer service an explained the situation. Within a couple hours I received an email from Amazon stating that they were sorry I had such a bad experience with my motherboard purchase and offered to replace it or give me a full refund! I could not believe it as I was way past the normal 30 day return policy:) Needless to say I choose a full refund because I will never buy anything from Asus again. Nor will I ever recommend an Asus product to anyone because their warranty and products suck. I immediately purchased a new EVGA classified motherboard to replace the X99-PRO through Amazon. All I can hope for is Amazon is able to make Asus eat my damaged motherboard and Amazon does not get stuck with it.

    • Paul Mudd


      • legitreviews

        Paul, Sorry to hear you are having a nightmare there. Was your board damaged in another area or something? Usually ASUS only denies a warranty claim if there is physical damage on the board, bent pins or something along the lines of user abuse. ASUS asking you to remove components and run 1-stick of memory shouldn’t have caused your board to go up in smoke after clearing the CMOS. Sounds like something went badly wrong!

        • Paul Mudd

          I am attempting to attach a picture they sent of the damage. I did not remove the VRM heatsink so I didn’t know it was that bad. The board was unrepairable. I am really thankful that Amazon refunded the full amount which I now have back on my card. I am waiting for Asus to send me back the damaged board so I can return it to Amazon. As far as I know the VRM was the only damage and I never smelled smoke or saw sparks until that last attempt to troubleshoot the board. Im getting an EVGA Classified this week and will be installing it in my case with all the same components. I just hope my CPU or memory was not damaged. I will know something by the end of this weekend.

        • Paul Mudd

          Hmmmm picture wont post.

          Well can’t get the picture to post here. If you want it please let me know. Thanks

        • Paul Mudd

          It fried my CPU as well. I purchased an EVGA X99 Classified MB and tried it but it would not boot and it displayed a “C” error code in the MB led. The EVGA support tech was great. He recommended that I send the CPU to Intel for warranty service. It’s at Intels depot now and I’m crossing my fingers that they send me a replacement without any problems. Dealing with EVGA was such a relief after dealing with Asus tech support. When Asus sent me my damaged board back they forgot to reinstall the VRM heatsink so I had to contact them…again. Next thing I know I received two packages with every heatsink, heat pipe, CPU socket w/backplate and all the white plastic parts that came on the MB! So thats three deliveries and all these parts. I wonder if it would have been cheaper for Asus to just send me a replacement motherboard. Had they done that in the first place I would have remained a loyal Asus customer. Anyway I replaced the missing heatsink and shipped it back to Amazon for a full refund 3 months after the purchase:)

          PS – can you delete all the duplicate pictures for me? I can’t access them.

  • yv35

    Thanks a lot for this usefull information. I just got a 5960x and a ASUS Rampage V Extreme. I got a Super Flower PSU which has a 12V SingleRail that can deliver up to 166,6A.
    SInce the tech in your article is a bit too high for my understanding, do I have to worry that this could happen to me as well? Sorry for the noobish bothering and I wish you a great day.

  • jack_foobar

    X99 sounds like a nightmare. I think I’ll wait for the next board to come out. No matter what review I look at, it’s a dice roll of mass component death, and I can’t afford that on high end hardware. Maybe intel’s design is flawed from the jump.

  • jsmith63

    Funny thing one week ago I fried my sabertooth x79 board . Replaced it with a second one two days later with the same cpu i7 3960x and corsair 1200ax psu it happened again. This can get pricey . Thanks for the info because I’m using the psu on an older computer till my parts come back maybe i should turn it on and off a few times.This psu ser# 12129502 seems to be the older one. Maybe the same guy did the soldering on that board too.

  • Silencer2079

    Probably a dead topic, but I have now been through what seems an identical failure to the above – twice!

    1) Asus X99 Deluxe, i7-5930K, Thermaltake Toughpower Gold 750W, Gigabyte G1 GTX980, 4x4GB Ripjaws DDR4-2400

    2) Gigabyte X99-G1 Gaming, new i7-5930K, Thermaltake Toughpower Gold 750w, Gigabyte G1 GTX980, 4x4GB Ripjaws DDR4-2400

    Both failures were the same. Build fine, boot fine, load software and drivers and running smoothly for about 10 hours. Then load a game that is seriously graphically intensive (ie 4x super sampling), and within ~ 60 min the system suddenly loses all power.

    Nothing will get it to turn back on again, the best I can get is the double click from the PSU OCP circuit and the half-hearted flicker from the fan led.

    First system confirmed as both board and cpu dead. Waiting on RMA for the second one.

    There are quite a number of reports of this type of failure on various X99 systems, different PSU’s and CPU’s used but the failure description is exactly the same.

    I have to say at this point I will be moving away from X99 – the benchmark vendors for these products must by now be aware of a systemic issue with these boards, but no new information is coming to light. It is, to say the least, extremely disappointing.

    • I think it must be something beyond the X99 platform itself, or something else in combination with it. Where I work we’ve used 135 X99 based motherboards in builds (mostly Asus, some ASRock) – with only 3 failures. That is well within the normal DOA / defective rate for motherboards in my experience, and so far as I am aware none of them have been catastrophic failures that took the CPU with them.

      Now with that said, I should note that we only use DDR4-2133 memory (the speed the CPUs on X99 are rated for) and we use only high-quality Seasonic and EVGA power supplies (occasionally Antec too, but not usually with this high-end of systems).

      Based on that, I can’t lay the blame on X99… at least not alone. Using it with a good quality PSU and the right speed of memory seems just as stable as any other computing platform.

      • Max

        Are your EVGA power supplies P2 or G2?

  • Nick

    And one more thing, when I press test I just get “00”

  • Nick

    I just bought an X99 Deluxe, Intel 5930, and 4×4 Corsair Vengeance DDR4. Installed it all and it booted up fine, then installed windows 7, system was running fine, but sometimes during start up it froze at the loading screen. Then after two days during a reboot it just shut down and wouldn’t start up again. First I thought it was the graphics cards since the VGA led was lit, removed them but to no effect. I then disconnected everything just leaving the power to the mobo and the cpu, still nothing. I tried removing memory to see if that was faulty, still nothing. the only time I managed to get the PSU to spin up was with only the 24 pin ATX connector installed. So Now I’m thinking either the mobo or the CPU is screwed or both. I didn’t overclock anything just running everything standard. Any ideas?

    • solomonshv

      it’s your memory. corsair’s RAM is trash. had the same problem on my Z87 mobo. had to do 4 RMAs with corsair before i got a working set of RAM.

      test each stick separately for 8+ hours each or until it produces and error. for me, the bad stick didn’t start showing error until 6 hours into memtest.

      and do yourself a favor, never buy corsair again.

  • David Anderson

    Great that Asus found a solution, I have had nothing but silence from Gigabyte on what looks like the same problem

  • tato

    did you experience any problems with standby-mode on asus x99 deluxe boards? if you have time, please test it.

    • We use these X99 Deluxe where I work, and the only problem we’ve seen with it and standby / sleep modes is when using certain M.2 SSDs. Are you using one by any chance?

  • David Anderson

    I had a Gigabyte X99-UD4 go the exact same way, but am using a Silverstone 1000W supply. The replacement UD4 board did the exact same thing, except this time burned a track off the board. The GFX card is OK, but I don’t know about the RAM and CPU.

  • Brent Busch

    So who paid for the toasted CPU?

  • Ironpipe

    I am on my 3rd Asus X99. Burnt up 2 ASUS ROG POSEIDON-GTX780-P-3GD5 Graphics Card. The first did not only fried the video card but the board also.
    New egg refused to take back the video card but the great company that Asus took it and replace with a new one. The second one I have not received the replacement from New Egg to date. Now I have the third board from Micro Center, who by the way exchange the boards with out any problem, no question asked. I am now running my X99 with a $50 Card. Still awaiting the replacement from New Egg to set up he most efficient self built liquid cool system and duel Poseidon SLI OC to max better than I have seen so far.

    • solomonshv

      what PSU are you using?

  • Long story shot, this why I’ll never purchase another ASUS or Corsair Product again, especially after this years dream machine. Install Corsair Link you gotta be kidding me right, useless along with ASUS Software bundle and a complete nightmare if you ask me, if you like checkout the post/article I wrote about this years dream machine on my blog, it’s annoying dealing with such issues.


  • sblantipodi

    My Asus X99 Deluxe is full of bugs when running on a 5930K. It seems that this motherboard has been tested with 5960X only. My uncore is locked at 3GHz if I use 125strap, no matter what I insert in the CPU Cache Ratio of the bios. This is a huge bug since it locks the cache to 3GHz.

  • Nicholas Perry

    Fantastic to see ASUS really own up to something that needed to be changed.
    They continue to impress me.

  • Gear head

    Yes I Agree both Asus and Corsair need to replace all products destroyed by there unstable products. ( Might I suggest a small claims law suite if they don’t. ) Now its mainly Corsair that look like a bunch of idiots trying to hide. I’ll buy Seasonic instead for my next PSU.

    • solomonshv

      FYI, some of Corsair’s PSUs are made by Seasonic. the AXi line of PSUs (like the one that blew up in this reviews) are made by an OEM called flextronix who aren’t very good. But you are right to avoid avoid Corsair PSus. the problem with Corsair is they customize their PSUs too much while their engineers obviously lack experience in this area.

      Other good brands of PSU you can buy is Super Flower or Delta. Delta PSUs are not very common in the consumer market like they used to be but you can easily score a beastly Super Flower PSU in the US that are sold under the EVGA and Rosewill brands (some models).

  • 1wayjonny

    Great follow up and conclusion.

    Asus you forgot to mention the courtesy for the less then 10 people with blown-up X cpus that cost a $1,000 bucks. You should be working with intel to find a way to replace this for users. Its just not right.

    Yes the corsair had OCP turned on but they didn’t step up because the motherboard VCCIN should have only asked for the correct load.

    The larger load also explains why this only happens to the X processors and not the K processors, the over clock on the X process might have asked for more power.

    I am huge Asus fan but you really need to eat the $10K in hardware and turn this into a further success story.

    The best thing you can do is own the issue (which you already have in great way) and repair the damage done by the issue in this case the CPU (which you have not even mentioned).

    I will continue to both use Asus and Corsair but Asus you will piss off many if you do not do the right thing. If this was my processor I would be on the phone right now with your team.

    If you actually take care of this in proper matter you will have publicity and look like a stand up company.

    I am not a huge Apple fan but I will say they always handle stuff like this really well. You are the Apple of motherboards so its time to act like it.

    Thanks LegitReview, I do agree this was risky to post but you have potentially helped Asus, the VRM supplier prevent a tons of more broken boards. You have also put Corsair on check about their decision to turn OCP on and made people aware and we all have learned.

    Not one company liked what you did but this is bitter sweet because everybody is now smarter.

    • Nathan Kirsch

      From my understanding ASUS or Intel has covered any and all processors that have dies. ASUS has also dealt with many X99 Deluxe owners directly and expedited the RMA process for them. from what I can tell ASUS is doing the right thing and spent nearly two months looking for the issue and then resolving it.

      • 1wayjonny

        That is good but this great review did not make that part clear, nor would I expect Intel to pick up Asus slack on the issue.

        I can see how any company would pay for this except Asus and they missed addressing this in the release.

        As of right now its still not clear but as long as users are not getting stiffed I think this is OK.

        I think it would be great for Asus to have mentioned it they coudl have turned it into positive issue say we will back any users with fried hardware.

        1) Bad solder joint
        2) BIOS was not regulating shutdown/restart correctly.

        That is two issues on Asus and I am a Asus fan all the way.

        Corsair OCP would have helped but its not their fault and its no wonder they didnt want to take blame.

        If anyone is not getting a good support form Asus in RMA in all hardware please let this thread know.

        I love Asus and my X99, I also just bought Corsair 1200Ai with the new firmware.

        I still support these guys and will continue.

      • Albert B.

        I read in the article that the cpu you were using was fried too, but what I haven’t read was if asus or corsair replaced that. I was wondering if they had done that or that they left you with the dead one.

  • Will Ovtuth

    Wow!! Talk about a “hot potatoe”!!! None of these companies want to touch this situation….not a good sign. Def sounds like it was a combination of things at the right place at the right time doing precisely the right thing to have a failure like this.

  • Silent_Scone

    That reps statement falls in line from what I heard nearer the time from certain e-tailers having issues…. E-tailers are less likely to make public statements about failures but I heard there was an issue with the IMC communicating with BIOS on the earlier release build…Allegedly Intel responded saying it was a BIOS issue. I am unsure of what board this was regarding at the time, but it rings true here.

  • PCJunkieXL

    Well, it seems you guys are getting the run-around. I don’t know why Asus seems to be so afraid as to why their board failed.

    It failed, big deal. This stuff happens from time to time. It was probably a combination of the PSU not having it’s protection circuitry on by default (way to go Corsair). A possible bug issue in the BIOS itself… which wasn’t explained as to HOW that BIOS bug could of caused the motherboard to burn up?

    So, I’m just taking a guess here, maybe the bug had something to do with the voltage going to the CPU, so it randomly jumped voltage up, causing a spike in amp draw, whilst the PSU didn’t catch it because this wasn’t enabled manually, and then the VRM goes bye bye!

    After that I’m guessing the other protection circuits in the PSU detected something bad and shut themselves down.

    It is interesting though, and I for one would like to know the official reason before I clunked down 300+ on a motherboard that possibly has some kind of fatal flaw in it.

  • DazMode

    Those delays looks really creepy. Will try ASRock X99 this time for a change.

  • Kilger

    Well, I dont think Asus will step up for this, but if you go googleing “Asus x99 deluxe” you will see lots problem over there. and also other asus x99 mb too. and the only different between asus and other brand’s x99, is their new feature oc-socket.. I will prefer not to use oc-socket, until asus step up and explain.

    • Stilgars

      Pure genius, to introduce an unique feature that kills systems … Thank you Asus.

  • Stilgars


    I had an Asus X-99 deluxe, intel 5960x and Corsair AX1500i combo. Somehow, my system just went poof (q-code 00 at boot), after the PSU did a click at boot.

    I am RMAing both the mobo and CPU, do you ppl think I am safe with the AX1500i, probably the most expensive and high-end PSU available for general public?
    I did not use Corsair link software.

    • Damian Konrad

      reg “somehow” – did you enable the OCSocket and start overclocking?

      • Stilgars

        Not at all, I had weird issues when I built up my rig, probably b/c the Asus was not stable enough with the first BIOS version, and gave up o/c for the moment.
        I did nothing special when it happened.

    • Gear head

      Another one bites the dust !

      Another Asus deluxe / Corsair X99 combo goes dead with both companies still providing no explanation for this abysmally high product failure rate. Its become rather obvious that people cannot not trust either company at this point. At least not until one or both take full responsibility for these obvious hardware failures.

    • Stilgars

      If Corsair and/or Asus do not step up in the next days and clarify what happened to my system while I am RMAing half of it, I won’t get either of their two products.

  • Tasos

    After reading this I don’t feel like buying a corsair PSU, I’d rather go for a Seasonic Platinum series.

  • Dying_in_this_Crap_World

    Just shut up and find a 50 dollar x99 board for us common folk.

  • What’s the probability this is Bios hotfix-able, so we can wait with enabling OCSocket and still buy the board? That’s all I needed to hear from ASUS.

  • Raghar de ishi

    This is comedy golden.

  • Buzzkill

    The X99 deluxe is the only X99 board that meets all of my feature requirements. So disappointed to see problems and a plethora of bad reviews. I planned to already have my new X99 build by now but given these problems and the problems I had with the Asus X58 Deluxe board it looks like I’m going to have to wait for several more months or even years.

    • solomonshv

      did you actually read those reviews? only 1 guy *thinks* he may have had the same issue but he didn’t actually test his CPU. and he was using also using a corsair AXi PSU (which by the way have 30% – 40% 1 or 2 star reviews). everyone else just makes references to this article.

      while there were 10 or so claims of DOA boards, that’s to be expected from the best selling X99 motherboard, one of the 3 models that were available on release day. but nobody actually said, “hey, this thing blew up my computer for certain”

      just don’t use a corsair PSU and you should be OK.

      • Buzzkill

        You may be right but given the cost of the board and CPU it makes me very hesitant to make a purchase. I am going to have to wait to see more feedback on the product.

      • ALI KONZ

        Google ” x99 deluxe memory only 12gb” or “x99 deluxe problem” and you will see PLENTY of people having issues with this board. Take into account that X99 is not by any means popular and look on how many people are pissed with asus X99 boards and have switched to other brands.

    • Outstanding taste!

  • Guest1

    “It feels like some people are trying to drag this out and hope it blows over.”

    well, not surprise with ASUS! just go check at newegg and tom’s hardware, or other pc forum, you will see lot asus x99 problem over there, and with different power supply. I will not say whos fault is it, but as least, asus should say something instand of hiding.

  • Jason Maxfield

    It would totally NOT surprise me that it was the fault of the PSU because of the current protection not being turned on by default.

    What kind of garbage is that by Corsair? At the very least, specify it in the manual! But, hey they reserve the right to change specs at any time without notifications…

    I’ve always thought that is a good way to jack the consumer, and in this case, it jacked up 1500 in hardware.

    I’m not so keen on Corsair at the moment… with particular emphasis on their power supplies. I built a new system for a friend of mine with their HX850 PSU. First unit, had high pitch squealing sounds before I even powered the system on. I immediately sent that back to newegg.

    Second unit, worked for 6 months, no notice of any kind of trouble, then one morning went BANG on my friends new rig! I was sure that it must of killed something in her rig. Turns out the surge went back into the surge protector and fried the socket on that.

    After placing a new PSU into her machine while dreading something might of died, it powered on as if nothing had happened. It’s been running fine for over 2 weeks now. Stress testing and using intel’s CPU checking program show no signs of issues at all.

    Oddly enough, the PSU barely had any signs of damage. Visually I could not see anything, and not wanting to void the warranty I left the case intact. I barely even smelled any electrical burning that would normally happen when a PSU blows.

    So, the 3rd unit should be arriving anytime today as I write this. Hopefully, 3rd time is the charm. As I’m very skeptical about Corsair PSU’s at the moment.

    • Marc McDaniel

      Hopefully the 3rd unit will work out fine for you. I have a Corsair HX1000 watt unit that I’ve had for about 3 1/2 years and it’s performed flawlessly. I’ve been using it with an Asus Crosshair IV Extreme, AMD Phenom X6 1055T and 2 GTX 570’s for that amount of time. However, I just purchased the X99 Deluxe, the 5930k and 16 gigs (4×4) of Corsair DDR4 memory from Newegg, which arrived yesterday. Been researching for a new case so haven’t even taken anything out of their boxes yet. Now, after reading this, I’m having 2nd thoughts about the X99 Deluxe. If it was actually just due to the bios, then that’s cool. But if it was something more, like the solder ball, then I guess I best exchange it for another brand. Not knowing is killing me!! What to do….what to do

  • Gear head

    screw Corsair and Asus, I’m gonna get a new MBP or something stupid instead and skip X99 all together!
    If it was my CPU and mobo these guys blew up Id be not only slashing there tires but launching a $75 dollar small claims suit against them both for the 10K limit and no lawyer costs.

  • 1wayjonny


    I can not believe they said they need a few more weeks after the last update.

    There a multiple X99 problems on NewEgg and multiple people have lost $1400+ in hardware.

    Asus you must have some info about all the people on newegg with broken boards and CPU’s.

    • Not an Asus apologist, though I will say I have several of their boards at home in my rigs. However, I just looked through all the 1- and 2-star reviews on Newegg for the X99 Deluxe and there are only *two* reports of people having boards die and take other components with them. Both were using Corsair power supplies, I think the same one LegitReviews used:

      Now I know Corsair is popular, but if there are multiple reports of the same board and PSU combo failing… that seems just as likely (maybe moreso) to be the power supply rather than the MB.

      Also, where I work we use the X99 Deluxe and have not yet had any failures. We have been running into some odd issues with them and Samsung M.2 SSDs, but that appears to be a firmware or BIOS issue not a failure of the boards.

      So with that said, lets wait and see what happens. I still have good confidence in Asus myself, and it sounds like Corsair dragging their feet at this point.

      [edited for spelling and grammar]

      • Nathan Kirsch

        I haven’t had any failures on the replacement board as well. It could have been something off or wrong with my ‘early’ AX860i with the older firmware. It’s a waiting game for sure at this point. I just hope they announce the truth after all this.

        • 1wayjonny

          What is going to be painful is I bet not Corsair or Asus will step up and replace the fried chips.

          If this happened to my $1K CPU with no replacement I would be driving to corporate HQ’s and start slashing tires on the cars.

          It is also weird its only been the 5960X, I have not seen one report with the 5930K, which I am using my self.

      • 1wayjonny

        I do agree with you and I only run Asus at home and I have 5x i7 machines.

        My first X99 Deluxe had the memory slot separated from the board. The second one was having black screen reboot issues.

        My third one was OK but returned at day 30 of my policy because of this posting.

        I did read the NewEGG review and most are non-sense postings or double posting from the same people. I even saw another bad post with different details helping drive the score down.

        I only saw two real postings in the one star section and third blowup in the TWO star section.

        Its scary and no-one is taking responsibility, I had to get a 4th board from a different retailer to hold me over for another 30 days and I have $4K in equipment that is not just going to sit here.

        The 4th board is OK but the head sinks and covers are scratched as hell and chipped, even if I keep this one I have to exchange it for a 5th one as I am not keeping this as a final.

        I am huge Asus fan and the quality on the board is great but damned if this doesn’t seem rushed and have bad quality control.

  • fkwl

    Wow time files! lol

  • Issues with ASUS flagship mobo pop up in the top Google results. It’s 8 days now since they requested another “day or two” – these delays are doing them more damage than admiting an issue and announcing revisions.

      you must not know how google works. they pop up in YOUR top google results because that’s what you have been searching around for.

  • 1wayjonny

    After the information on this comes clean, I would hope that if an Asus issue they would announce which of the X99 board this issue effects.

    I would find it hard to believe that this is only a X99 Deluxe problem.

    I just returned my second X99 Deluxe and have a gaming rig with no back bone as my 30 days were up at Microcenter. At least I got my money back, I just need to find a board.

    I am looking X99-E WS or going back to deluxe, red is not my thing.

    Come on Asus this is taking way too long.

  • Gear head

    Over one month and still no answer?!

    I for one will be either purchasing a competitors product going forward or skipping X99 now. It is disheartening how both Asus and Corsair are behaving with regard to this matter. Not only have they managed to scare myself away from a planned X99 purchase but im sure many thousands of other potential customers as well.

    I can only assume Asus is not responding because so many of there x99 boards are failing that they are swamped by the returns at this very moment. As I mentioned earlier in this thread according to Newegg reviews, over 50% of the boards appear bad according to confirmed owner reviews and almost every review is followed by an Asus apology from ” Lou” in response. Of course Lou has never responded to my queries. The liabilty costs associated with resulting damage from a bad design or part cold be rather high for Asus and Corsair has there own troubles as they are liable for changing the single / multi rail and advertising a different setup to purchasers.

    As an after thought, I wonder if SATA express connectors / hype drive will ever come out or was that just another scam? Heck, they been putting these ports on mobos since Z97 and still nothing, nada, zip?! Nothing much has improved since I purchased my first PCIe SSDs way back in 2009 ! Where’s all the darn progress?

    • solomonshv

      it looks like you didn’t actually read the reviews on newegg. while some people did get faulty Asus X99 boards, i can assure you that other brands such as gigabyte have shipped just as much if not more DOA boards. most of those newegg reviews are idiots talking about this article over and over. same thing goes for the reviews of the EVGA GTX 970 cards. 1 or 2 people got DOA cards but most of the reviews are bitching about the cooler design after reading articles about that.

      i went through 3 faulty Gigabyte X99 gaming G1 boards until i finally gave up on gigabyte and got an Asus X99 Deluxe board instead. it’s been working great for me and for my brother so far. both of use are using Super Flower PSUs and 5930k CPUs.

      as for this article, i’m willing to bet good money that this is Corsair’s fault. over the last 2 years or so, every corsair product i bought has been defective and had to be RMAd at least 1 time. my H110 cooler came with a broken pump, my obsidian 750D case came with broken USB 3 ports. bought 4 sets of vengeance RAM. one set wouldn’t even post the others gave random BSOD. i had two corsair CS450 Gold PSUs that i used as replacements in Dell machines, both died within 2 months. the list goes on.

      • Gear head

        I have indeed read every review but It looks like you didn’t. Also if you read this thread you would have realized we are talking specifically about the Asus x99 deluxe board.

        Gigabyte, never used them and Corsair I wouldn’t use or reccomend them either. If fact most manufactures have become incompetent and complacent these days and I trust few to deliver a proper product in good faith.

      Scientific work needs at least one year of unpaid work, and results need to be delivered to politburo in triplicate.

      Failure of doing it in triplicate can result in half year in jail. Receiving money for doing scientific work, when the person could do proper honest menial work, and the scientific work could be done in his spare time/overtime as an example of his fervor, could be punished by 5 year of forced labor. Or transfer into scientific camp to Siberia, where he wouldn’t need to be paid because food and clothes would be provided on site.

      Socialistic scientific system was very efficient when money and time spend were taken into consideration.

      I guess Asus should educate themselves from masters.

    Reading some posts on a burned x99 deluxe and some other issues with x99 mobo’s, I became a bit scary, but I decided to put it all together and start it up.
    I took the risk and could not wait any longer. All the stuff I ordered was just sitting there. So, the Asus x99 de luxe mobo, Intel i7-5960X 3,0 GHz, 2 G.Skill 32 GB DDR4-2400 Kits, Corsair AX 1200i, NZXT H630, Asus GTX780TI-DC2OC-3GD5, NZXT Kraken X60 and some small stuff like extra fans, blu ray and SD cards reader.

    For the disk setup I went for two Samsung XP941 512GB M.2 NGFF PCIe x4 SSD’s (one OS and one software), a Revodrive 350 480 GB (scratch) and a Revodrive 350 960 GB (photo disk) and 4 Samsung EVO 1 TB SSD’s (two striped sets for video) and 3 WD 6 TB disks (mirrored backup disks).

    Encountered some issues. Had to find and buy a internal header expansion card for USB 2.0. The x99 mobo has only two USB 2.0 headers and I needed 4 of those headers. Found an extension card from NZXT for that. Several tries for the M.2 SSD as an OS disk (formatted it to fast, and it had to be a GPT boot disk, no issues after that). Could not get the Revodrive 480 to work as an OS disk and found no way of loading the driver first, so Win 8.1 did not see that drive when installing. So went for the M.2 then as OS disk.

    That’s was last week, and still no issues at all (yet). It is pretty dammed fast and it all runs super smooth and so fast, unbelievable how Premiere Pro, Photoshop and (a bit less as it is not well written for multi core) Lightroom are running.

    But…… it is annoying tht there still is an amount of uncertainty…… upgraded the Bios to the latest version, as I read it solved some issues.

    • Mario

      Hmmm, reading the last post I am starting to think that perhaps it could be a wise thing (to be safe) to replace my Corsair PSU……

  • Concerned

    Wow this is getting ridiculous… over a month ago and still no answer, meanwhile already 2 more reports of these boards burning on newegg… I think im just going to return my X99 Deluxe…

  • ItNeverEnds

    Asus has been promoting the x99 Deluxe as a workstation board for video editing, while the x99 E WS goes entirely unmentioned, though supposedly released at the same time. Nathan do you have any idea at all, or an educated hunch, or even a blind stab-in-the-dark guess, as to when if ever this thing will come out? — and how long after that it would be ready for prime time? No (real) answer from Asus email address.

  • “(…) We have been told that it will be another day or two until they will be able to say something. (…) the results are being looked into by both companies. ”

    In other words, Asus needs another week to design and roll out their PR damage control, and split the blame with Corsair, so the OC socket can survive.

    • rte

      Gigabyte X99 LN2 also has a OC socket.

  • Gear head

    Asus X-99 deluxe motherboard has an over 50% failure rate.

    As of today on the Newegg site there are 37 confirmed owner reviews for the X-99 deluxe and more than half have fried, died or arrived DOA. The unavaiable Asus x-99 E WS has 3 owner reviews and 2 out of 3 have died.

    If Asus was a doctor they’d be carged with mass murder by now. Over half of the motherboards are failing, geeze that’s a bloody disaster. I’m to scared to buy an Asus Mobo now!

    • For what it is worth, I work at a system builder and we use the Asus X99 Deluxe. So far 40 systems built with it, no failures at all.

      At the moment, we don’t use any Corsair power supplies – and we also don’t use memory clocked higher than Intel’s spec for the X99 chipset and accompanying CPUs (DDR4 2133MHz). We have overclocked CPUs on that board, though, without issue.

      • Gear head

        Very good to hear of your positive experience so far, surprisingly yours is the total opposite of Newegg builders and most of them claim they were also stock when things went south.

        Not sure why the difference but I find it more scary that results could be so contradictive rather than consistent either way.

        • Yeah, I am interested by the discrepancy between our experience and those of individuals and review sites like this one. I have been following this article and its comments since it was first published, and am quite curious to see what Asus and Corsair end up putting forth as their conclusion. Have you seen any common threads on the Newegg failure reports? A specific brand of PSU, memory, or anything?

        • solomonshv

          of all the supposed failures the above clown “gear head” is talking about, only like 5 people actually said that their board had failed, but it wasn’t a total blow out where everything died. most of the people giving 1 or 2 egg reviews are just quoting this write up.

          i built 5 system with an asus x99 deluxe, all running EVGA (Super Flower) PSUs. all 5 have been running for a month and half and none of them have blown up yet.

    • any failures with 5930K (i.e. anything less powerhungry than the top of the line X5960 ?) please paste a link

      • hdhdj

        They all have the same tdp.

        • solomonshv

          while TDP is the same they don’t actually use the same amount of power. the 5960x uses about 25% more power than the 5930k. and the 5930k doesn’t use anywhere near 140W, which is its TDP. mine is overclocked by 30% and still pulls under 90W at full load.

    • solomonshv

      i built 4 workstations and 1 gaming rig with the asus x99 deluxe. all of them use EVGA (Super Flower) PSUs and G.Skill 2800MHz and 3000MHz memory. they were built between august 30th and september 5th. none of them have died.

      most of the people writing bad reviews did NOT actually get a board that failed. they all are just referencing this write up. they are all idiots like you

      • Gear head

        Hey Solomonshv, suck my you know what !

        • solomonshv

          i would, but then you’d be unemployed.

  • jlt

    I think asus vrm got confused when it always though corsair psu was single rail but them new ones are multi-rail so it went alg alg alg before going up in smoke. just like Arnie* in Stolen Identity 3. 😛
    *not the real Arnold

  • Fanatoli Guyoff

    Sounds more like the solder balls were probably the reason for the failure and not the result of it…but that’s just a thought.

  • Mario

    Hmmm, this goes the way of a power feed issue in the design of the mobo but not only on the Asus side. Chipset design issue?

  • Gear head

    Just a guess here but If this was some other manufactures fault Asus would have announced it immediately. By taking far longer than promised to respond means they are likely to blame and need to think of a way out.

  • I assume the 2-5 days was requested by the PR representative from Asus. 10 days looks very unprofessional, they better have a good excuse, because to me as a customer it only sends a bad signal. Right now hesitating between ASRock EVGA and ASUS. Why is there no complaints about ASRock and EVGA x99 yet? I’ve already got white tubes dammit 😉
    Another thing, correct me, failures only happened with X5690 + ASUS/MSI, right? This could mean we are safe with 5930K or another mobo (until Asus update).

      EVGA boards have sucked since Z77 boards first came out. there are still tons of unresolved issues with their Z77, X79, Z87 and Z97 boards.

      their graphic cards are for the most part excellent. one thing i don’t understand however is why EVGA insists on making 10+ versions of each high end card when 7 or 8 of the those versions are the same exact thing.

  • Mario

    Just installed it. Bios update 904 is what it is actually. Only EZ Update tells it is

  • lw

    There is a new bios version on asus ez update program, but the site itself does not list it. Hmmm….

    Still no news?

  • Gear head

    It is October now.

    Asus, how’s the ” silent” x99 Mobo recall going?

  • sfke

    It’s almost October, any update from Asus yet?

  • Gear head

    Asus its been 8 days? Wheres your response? you
    asked for 2-5 days , come on already!

  • Raghar

    What’s new?

    • Nathan Kirsch

      ASUS should deliver the final response tomorrow if all goes as planned. The replacement Corsair PSU’s aren’t here yet, so still waiting on those. That is all really.

  • swing84

    “On Intel Haswell-E processors all five internal power rails are pulled from the single VCCIN” – Thank you Intel.
    As to the ASUS motherboard, I will not be purchasing that puppy. I stopped building computers with ASUS motherboards since the late 1990s, when quality went down. Your picture indicates a quality control problem on the motherboard.

  • swing84

    What the hell is “virtual multi-rail”? Virtual = almost, but in computers it means something else. Is “virtual multi-rail” simply a single rail with separate rails tied to it?
    Thank you for NOT explaining.

    • Nathan Kirsch

      From Corsair: “Multiple +12V rails on 99% of the PSUs out there are often considered “virtual” because there isn’t actually multiple, physical +12V rails. You usually have one +12V rail and then that +12V rail is split up into several different circuits, each with an OCP on it. So the term “multiple +12V rails” is actually a misnomer because literally what you have is “a
      split +12V rail”. Therefore, people often use the term “virtual”.

      If a PSU had actual multiple +12V rails, there would be multiple +12V outputs. That’s simply not the case in most of the units out there.

      The rare exception is some older, high capacity PSUs. But for the sake of better efficiency, this simply isn’t done anymore.”

  • Raghar

    Is there any news on X99-E WS?

  • cm

    More than 2 week, asus without any update yet?

    • Nathan Kirsch

      ASUS has asked for 3-5 more days for testing before making a final statement. It sounds like they are looking at solder points and traces right now.

  • michele

    i7-5960x is thirsty for power, asus underestimated the power?
    an example asrock boards have to support a power 1300w!!!

  • michele

    Asrock 16phase VRM. Good for x99!!

  • Jonathan

    This exact same scenario happened to me yesterday. Wish I had read this before going in to the bios. This was my one spending spree on a machine of dreams and I don’t know what to do now. My power supply was Seasonic 1050X platinum, so it’s not because of the power supply, I think.

    I’m so pissed and sad.

    • Jonathan

      To clearify, I bought another asus x99 deluxe and got the 00 error code. Now I guess I’ll start doing my renderings on my old i870 until I can get a swap on the processor or put in on insurence or something. Good times.

      • justin

        I too had my x99 deluxe fry my 5960x, only a month of use.

        • Would you mind sharing what power supply you used? So far the only confirmed reports I have seen (here and a couple reviews on Newegg) were all using Corsair power supplies.

        • airedad

          Not all – I had the same thing happen with a CoolerMaster which has 3 19amp 12V rails (it’s only a 650 watt PS and I have a larger CoolerMaster on order now. But it tests out as entirely within operating specs both at low load and at full [650 watt] power). So I don’t think it’s ONLY the Corsair PS.

        • Tyson Merten

          Cooler Master PSU’s aren’t good enough to use in an X99 system.

          I mean they are, technically. But they are crap.

          I have the exact PSU as the one here (AX860i) and I blew one last year (my bad though). Great PSU. So amazing.

      • airedad

        I tried Asus when my X99-Deluxe burned both itself and my also brand new i7-5930 after about 8 weeks of smooth running at low to moderate loads.
        The technician put me on hold and then came back a couple of minutes later and said (as if he were reading it) something like “Asus is responsible only for the parts IT delivered as part of its motherboard or its accessories. It is not responsible for damage to anything else.”
        I went instead to Intel, and after taking a complete description of what happened, they’re replacing the CPU under warranty.
        I suggest you contact Intel.

      • Thank you for this post!

    • Raghar

      What do you mean going into BIOS? Did you do something in before explosion?

    • airedad

      This is written long after the fact – bought my MB and CPU and assembled my system about 4 months after your review came out – Same MB but (luckly??) “only” the 6-core i7. It ran beautifully for almost 6 weeks. Then suddenly PFFT! smoke and a nose-some burning smell.

      Yes, the CPU was dead as a doornai, too. HOWEVER, the PS was NOT a Corsair so that can’t be the problem. It DID end up with (or start with) the “lovely” solder balls.

      Now I don’t have the $$ to have an extra MB and CPU sitting around so I put back in service the one I had replaced in building this new machine. Then I was able top do a bit more research and contacted ASUS. It only took 9 (that’s right, NINE!) attempts before I got to speak with someone who sounded the least bit interested in helping me. He finally funneled me of to someone who actually (sounded like he ) DID want to help me.

      But it still took 3 weeks to get a replacement MB. But fortunately Intel knew about the problem when I contacted them and I had a replacement in only a few days. And I thought I would be OK once I got the replacement MB.

      Wrong. The replaement MB was DOA. The socket-protector had not been properly placed over the socket, and it had moved around quite a bit. One thing it did was to “hose up” about a dozen of the pins in the socket. You guessed it. The replacement MB was DOA. So then I got to start all over. with ASUS.. They actually wanted to send me a “refurbished” MB since the one I was returning was not the one I had originally bought, and I think that (all promises, explanations, etc. aside)l, I think that’s what they finally did send me (there were “interesting” marks on the MB indicating that it was used OR that it was tested before sending and handled fairlyh roughly). All in all it took roughly 4 months from the failure of the FIRS X99 to getting the SECOND replacement MB, and IMHO this was not good.

      To make a long story short, 3 weeks after the 2nd replacement MB arrived it stopped POSTING at all and at that point I threw up my hands, gave up, and replaced it with something else – something a lot more reliable – and from a different company.

      Since all this happened I have spoken with about a dozen other people all of whom have had “somewhat similar” experiences with this particular MB. All of us basically felt that what ASUS shipped in this MB was not really ready for production use, and there were clearly an unusually large number of MBs which experienced the burn out (“SIDS” perhaps?) syndrome usually in the first 6-8 weeks of use.

      BTW, for what it’s worth I have been building PC’s for my own use and for our lab (office) and for occasional family members and friends. Over the last decade I have built roughly 130-140 PC’s (all from scratch using higher end components) and I’ve only had 2 such failures, both coincidentally from ASUS. I mention this only by way of saying that I am a long way from a novice at building systems, and except for 2 different memory modules which failed over the years (and were replaced immediately under warranty) these were the only two “flaky” system which I’ve ever built.

      YMMV, and thank you for this review – I read it about a year ago, but I never had the time until today (I’m building a system for someone who specified a particular ASUS MB for it) I never had simultaneously (a) the time to write this note and (b) the urge to do so.

      • sdmf74

        Companies like Asus and Corsair (the worst) will NEVER give the same level of customer service to individuals as they do to reviewers for obvious reasons. It’s just sad cause most of us can’t afford this hobby but we make sacrifices cause we love it. We don’t have 3 backup power supplies and $400 motherboards of the exact same model just sitting on the shelf yet you see how fast those replacements came in! We get told “sorry were don’t repair those anymore and we will not be replacing it either”(Corsair RMA dept. Response to me after 2 failed mech keyboards recently) but we are partly to blame and should not continue to buy any products from them. I confess I still have a corsair mouse Matt but have sold or trashed all other corsair items in my rig.Thankfully we still have companies such as EVGA and G skill and swiftech etc. That know the definition of a warranty and provide oustanding customer service.

        • Allen Michael

          I’ve delt with Corsair many times and never had a single problem my self contacting them, they are usually quick to issue an RMA even for the dumbest or easiest fix I could do my self but was more or less seeing if it was a common issue like the h100I fans not able to rotate at 5v.

          Asus I can’t comment, but my Asus P8Z77-V has been working great other than the bios always fighting me after a bad overclock, like its perfectly stable at 1 setting, you up it just a bit and its no longer stable reset cmos and set it back to where it was stable, and it still wont boot. Try it again later and its fine and stable for hours running Prime, makes me want to pull my hair out sometimes.

          My Asus x99 Deluxe has been perfectly fine other than a older bios didn’t like my RAM much and kept displaying 3 out of my 4 sticks or sometimes 2 sticks were missing after a reboot but all 4 sticks always showed in the bios, Updated the bios and its been fine ever since with a 5820k at 4.6ghz and a EVGA Super Nova 1300g2.

  • Wei Day

    my S/N is 1237. am i safe on my AX1200i?

  • Raghar

    Well 12V/90A, or 12V/40 A for a normal single rail PSU isn’t that big difference. Flames are bit smaller, and that’s all.

    These metal balls are problem. When Asus went into ODM methodology, they lost some control over process. Also I wonder if boards are designed to be resilient to standard user damage, and common manufacturing related problems.

  • Cinder Elli

    Thank you for keeping us updated. I just got a private message from a fellow forum member on who had the same thing happen on the same motherboard. He mentions that he has heard there is a recall now on the motherboard, I have no idea where he ” heard ” this.

    • Nathan Kirsch

      I heard early on that ASUS was asking for boards back from reviewers, but there were also reports that other motherboard makers were offering to pay other sites to post this up as news (those were found to be false). ASUS has made no mention of a recall or an issue with their design to me as of this morning.

  • rather stormy comments, i am leaning with Kuba Ober and the micro macro solder balls, arching over, after close thermal lowered the temp to metal migrate the ” blob” this happens over time, just good observable tech going on here, for me, thanks.

    • Nathan Kirsch

      yeah, it happens with some folks. There is some good findings here and I have learned much from this post. It has also uncovered some things that were previously unknown, helped play a part in a company changing the voltage on their memory kits and more.

  • davidber

    @nathankirsch:disqus Awesome updates to this. Reading the updates, it might technically be a power supply that caused this, but in the end we will have to see a new motherboard rev. Getting people to change or know the level of technical depth of their power supply is not going to happen. I do wonder though if this is something that Asus could actually solve in the BIOS though.

    And to let you know, your review did impact me and I did not buy the X99 deluxe. I bought the Rampage V instead 🙂 Now I just need EKWB to hurry up with their full motherboard block.

    • When did Corsair change the firmware on the AXi series of power supplies?

  • Roy

    I think you meant a single rail might have exacerbated the damage. I suspect it was you who was exasperated….

  • Rey

    I have EXACTLY THIS!!

    I am on my second motherboard now …..and it instantly blew up

    • Nathan Kirsch


  • Chiam Goldstein

    Around blacks, never relax.

  • should make 1.5V not an option

    1.45V should be the absolute maximum for current power controllers

    in the future if they do implement bigger ones to sustain more power then 1.5 could be but as of now they shouldn’t

    would be bad that people later on who get it 2nd hand do 1.5V fry the board and have no RMA lol unless a bios update can pass through that 1.5V cannot be a possible selected option

    • Nathan Kirsch

      ^^ Kingston reduced all their kits that were at 1.5V to 1.35 this week!

  • DarkJoney

    Oh, god, this so bad. I will never back to ASUS, cuz my M5A99FX Pro R2.0 burned after FX 8320 4.5 ggh overclock, and it was unstable on 4.2. ASUS can’t do overclock 😀 With same CPU on Gigabyte GA-990FXA-UD5 I reached stable 4.6….

    • James Baranski

      Azuz M5A99FX had VRM problems. This is not new news DarkJohnny…

      • DarkJoney

        Really? didn’t knew that.

  • Kuba Ober

    You’ve got it completely wrong with the solder balls. The balls weren’t there due to the thermal damage. They were the cause of it and were present on the board from the factory. Those balls are a common side effect of improper design-for-manufacturability (wrong paste mask openings in the stencil, etc.). The blow-up was most likely because a loose solder ball has contacted the pads of the mosfet and has likely vaporized.

    • Nathan Kirsch

      highly unlikely as the board was used for hundreds of hours of testing over the two week span leading up to this. The board wasn’t moved, so for a loose solder ball to move on its own and fry the board would be a bit of a stretch. Anything is possible though and ASUS and seen all the images and of the failure scenarios they have shared with me that is not one of them. The board has been packed up and sent back to ASUS along with the PSU that was on the system at the time of failure. ASUS will be hand carrying the PSU to Corsair to test it on the Chroma this week since I’ll be at IDF and unable to watch the testing as it will take a number of hours to run all the tests required.

      • Kuba Ober

        The solder ball was already there, likely in mechanical contact with the pads. The only thing separating it from from the pads was a thin coating of flux. As the voltages are very low, it doesn’t take very many layers of flux molecules to keep it at bay. Eventually the minute vibrations and thermal cycling has worn it off. Those balls have nothing better to do but to stick in tight spots such as between the heatsink and the PCB. They are mostly harmless everywhere else. The fact that other boards have supposedly failed in a similar fashion would indicate that there’s a consistent process issue at play.

      • swing84

        Kuba Ober is saying the only insulation [at the solder ball] was a thin coating of flux.
        I agree that motherboard inspections should take place, especially at known problem areas such as this one. And, the motherboard should be checked for a short[s], too bad you did not check for this – or have probes small enough to check before sending the motherboard back.

        • Nathan Kirsch

          ASUS has the VRM component maker looking at this board with them this week. We don’t have the abilities to look at boards failures in such detail and ASUS has called in all the forces.

      • ASUS is needing more time to discuss what they have found out with Corsair before making a public statement. We have been told that it will be another day or two until they will be able to say something. It sounds like some issues have been found during testing and the results are being looked into by both companies.

    • SnipSystem

      I’ve never seem solder balls comming out of an unpopulated components footprint. (5 years in board manufacturing, team leader).

      They more likely form when solder paste leaked, for some reason, on the soldermask. It could be a dirty stencil, a stencil missplacement, too much paste (stencil too thick) or pick and place splatters (yeah, components are placed at high speed and sometimes the paste gets ejected around). Usually components that have a lot of paste under them are marked in the placement file, and special placement speed are programmed for them, but big caps are often overlooked and in a design so sensitive it often leads to splatters.

    • SnipSystem

      Oh ! And, I almost forgot. I think I understood that the board which failed was a pre-production board, so there is high chances the assembly was made on a old assembly line; with all the problems it involves.

  • George Daws

    It’s a shame this has happened. I guess, like NEW Cars, there is always going to be a teething problem. I hope it gets fixed soon or this NEW X99 series could end up like MS’s Vista. 🙂

    • David Calloway

      This is not a teething problem, especially on 1.5K of hardware. This is something that should have reared it’s ugly head during extensive QC. This type of thing worries me that the private sector has effectively become the QC department for so many OEM’s. BTW MS’s Vista was nothing more than a W7 beta. : )

  • James Baranski

    Really a stupid write. Reviewers know that shizza happens and making an ass hat post like this would lead readers to believe this is a bad Asus board. Many things can make a board go bad such as user(who knows here), PSU, perhaps there was a storm last night with a power surge, short,bad grounding, ect… Really bad taste to make an article on this. If I were JJ at Asus, I would be all over you for this….

    • Nathan Kirsch

      James – We already reviewed this board, processor, power supply and so on and recommended them all. Would it be right to just sweep it under the carpet and keep it all off the record. That happens so many times, but this is on all retail hardware. The site wouldn’t be called Legit Reviews if we couldn’t post what we wanted and the truth. If multiple sites had this issue and didn’t post it because ASUS asked them not to say anything who would that help? If there is an issue shouldn’t it be known? I never said who was to blame, just that we were looking into it. Also, ASUS was alerted before the article was published.

      • James Baranski

        It is dead wrong. A board can be simply “bumped” and a solder point can be damaged. Without scientific “proof” it is the boards fault, it is really asinine to write an article like this. If you have any background whatsoever, you should also know that power supplies go bad. Unless there is a pattern of many boards going bad, this is a non issue. I will say, your credibility is 0. I reviewed boards for years…

        Also, like mentioned, human beings are also involved in manufacturing the board. If a Mercedes 500 series has a bad alternator on a brand new car, do you see the Auto magazines making a specific post on that particular car. Nathan, as mentioned. Really stupid article. 1 bad board does NOT entail an article on this. You seriously need to get a clue.

        Just because you made the write does not make it appropriate. If you reviewed multiple board and had an issue, than yes. You cannot take an isolated issue and make a write like this. If I were JJ, I would ay GFY. Just saying….. No more boards for you..

        • davidber

          I would say your credibility is zero Mr. Baranski. If you look at where this occurred on the board, to say it even could be a ‘bump’ is so far fetched that the odds of winning the lottery two weeks in a row is better.

          Personally, I found the article to not have any bias and just explained what they saw and what they did. At no time did they bash Asus. At no time did they say they even had a conclusive answer as to why it occurred. You can read that they are not sure if it was memory related, power supply related, CHIPSET related or even motherboard related.

          For one, I appreciate the article. It has impacted me. I have purchased my 5960x and am debating between the X99 Deluxe and the Rampage V. This ultimately could be an issue with the chipset where all the MoBo makers are going to have to have another rev that fixes some issues. Considering I am typing this on system that has an Asus P8P67 board, and all the ‘revs’ that Asus had to do there, I would not be surprised if we had a rev B within a month.

          Now back to Legit and their writing . . . Honestly, this site was generally 3rd or 4th on my list for reviews. Because of this, it is now first. Honesty builds credibility. They have shown they are honest.

        • James Baranski

          My credibility 0? Humans make the board. Do you see magazines reporting Mercedes S500 when they have an alternator go bad? No. There is noway to tell what and how this board went bad. Pretty simple. Are you an electrical engineer or a motherboard developer? No you aren’t. If another was reviewed and the same issue occurs, then there is an issue….It could be a bios issue, handling issue, PSU issue like I explained earlier. If you knew about motherboards, this would NOT be a chipset issue and the Deluxe and Rampage X99 uses the same chipset…. Chipset is designed by Intel, not ASUS. There is no review website in the industry that writes a negative article when 1 board goes bad. Now if there is a trend yes……

        • Nathan Kirsch

          James, you are a motherboard reviewer for another PC hardware review site. Is your review up? Instead of coming over here and arguing with everyone and telling everyone what a crap article this is why don’t you just review this board yourself? Maybe you’ll confirm what I saw. That would a bigger help to the community that arguing about something that is already done.

        • James Baranski

          Actually, retired Nathan… I am not arguing, your writing is #1- incomplete. Writers do do leave articles open ended. If you could see, I am explaining to the community that 1 board is not a reason to write and article. The problem as I explained…. some readers can get a negative opinion about Asus or the X99 board in question when you have no proof of what caused the issue. REVIEW ANOTHER DAMN BOARD and complete the article. It is not fair to ASUS that you report this issue when you may have used excessive voltage. Perhaps you did, perhaps you did not. How many amp fuse are you working off of? How much do you have plugged into the circuit? I built a rig for a guy who had old electric in his home and a 15 amp circuit with too much plugged into that circuit resulting into blowing 2 boards. I am just coming up with some of many things that could cause fault. There is no professional reviewer, writer that would publish such nonsense without an explanation and you have none pal.

        • Jonathan

          Just ban this guy. He totally ruined the comments section on this very informative and useful article. You never once blamed ASUS or Corsair or Intel but you shared your objective experience with this brand new chipset, socket, CPU, and RAM combination. This very well could be a faulty PSU, or mobo, or the DDR4 RAM voltage might have been unsafe. Or it could be indicative to a flaw in the chipset design under high loads and we could see similar cases popping up over the next few months as more and more people use the platform and push it. Remember the VRM issues with the 590 and boards going up in smoke? I was glad for review sites mentioning their experiences with that as were other readers and in this case, I am glad you mention this.

          So to summarize, there’s nothing wrong with this article because it could be a 1 off fault mobo/PSU failure (which does happen) but considering how many things are new and untested here, having your experience shared with us lets us think a little more objectively. Jumping onto the new tech bandwagon is always risky and this time it could be more so. This jerkwad with a massive stick up his butt hating on you is a blight to this site and, in my opinion at least, should be prevented from ruining legitimate discussions on the comments here. The comments are completely unreadable for 2/3’s of it because of him.

        • marsofearth

          Naw, disagreement is healthy for the open minded. The only person burning up is Mr. Baranski. At this rate he will be up in smoke in no time. he he ….

        • Do you have a vendetta against LR or something? Yes, this article is open-ended – it has to be given the nature of the incident. You’re correct in that mishaps like this are not totally uncommon, but the fact of the matter is, the article linked to another website that had experienced the exact same kind of issue. That right there proves to me that this article has reason to exist. That incident didn’t even involve the same motherboard, and Nate was clear on that fact (and also the fact that he wasn’t pointing the finger at any company in particular).

          “BTW, when there is an issue, good writers do not leave the article open ended”

          Your solution is to hold off indefinitely, then? This is an issue that popped-up a mere week after launch, so holding-off isn’t what I’d consider to be a smart idea. With it out there in the open, these companies can get to figuring out what the issue was rather than shove it aside, because again, this wasn’t unique (taking Phoronix’s experience into consideration). If the article isn’t published, the companies involved could rinse and repeat their “it’s a fluke” message to Nate over and over, while the problem can potentially still exist. That’s not great when consumers will be dropping a significant amount of money on the basic components of this platform.

          “Actually, retired Nathan…”

          I’m sure every consumer who wishes for transparency will be glad of that.

        • James Baranski

          The solution is to get another board from Asus. If one faults, Asus will send a new one in days. Just pop it in and test it..

        • davidber

          You keep wanting to drag cars into the equation. The only thing that a car has to do with this is that I will get into one to go buy this equipment. It is a piss poor analogy. Stay on the subject matter at hand, an Asus motherboard.

          You do have zero credibility. You assume that I am to believe you are some know it all who has reviewed boards for decades and has a Q score high enough for me to know. Fortunately we are on the internet and the virtual world is large enough for your ego.

          At this point I am starting to believe you work for Asus or your reading comprehension is terrible.

          I suggest you re-read the article and point out where they blame Asus. When you find it, please highlight it.

          And yes this could be a chipset issue. Intel designed the chipset and set the reference. If you read the article you would notice that another board also had an issue.

          +1 for Legit and their unbiased review.
          -1 for Mr. I know everything

        • James Baranski

          It is on the matter… BTW, when there is an issue, good writers do not leave the article open ended. They write a complete article and until another board is tested, the article is not complete. Writers do not say” stay tuned”.. You could have your opinion of course but what is the difference from a microwave, automobile or motherboard that goes bad. If it is an isolated item no biggie. If it is a multiple product issue, there is a problem. I guess this is something you do not comprehend. Sorry about your thinking…..

        • Nathan Kirsch

          Another review site writer coming over to troll? Let’s just stop feeding him. His character assassination has failed.

          but atleast its got asus and corsair and all the other manufacturers thinking………
          according to me after using couple of diff manufacturers and real usage data from other friends

          best z87 board ….gigabyte g1 sniper m5
          best z97 board ….asrock oc formula
          best x99 board ….give me couple of months and 10 thousand dollars ….i will tell you ….lol

        • Patrick Thomas Cabahug

          James Baranski, I guess you never heard about a consumer right to know. As for Nathan Kirsch writing this article, it is worth noting for everyone consider buying this board. Since it posted public like the other users commented they are likely make new revisions of the board. Which is a good thing. This site is called Legit Review. I suggest you look up what legit means.

        • Bill Stelling

          If you want to blog, go back to work.. It appears you read the title of the article, formed your opinion, and without reading it you started posting. Next time read the article.. It is really helpful and people won’t mistake you for a post troll for totally going off topic..
          The article is not about Asus, but one of their boards frying along with an Intel CPU – cause unknown..

      • James Baranski

        Asus can easily ship another board and if you have the same issue, then write the article…… Sheesh…. I have had isolated issues with boards form all manufacturers but seeing it could have been my fault, transportation, my own hardware… it DOES NOT ENTAIL negative publicity…… I do not and WILL not consider your site a “LEGIT” REVIEW SITE… AND NEITHER SHOULD THE READERS.

        • that is a little harsh James. and Caps, does not give you dominance, we glen knowledge here by facts and sharing, not condemnation

      • marsofearth

        Thank you for writing your experience and findings. Sure one offs and accidents happen. I found no accusation of blame in the write up, and feel a lot of readers will be interested to find out what Intel’s, Asus’s explanation is.

        • well said, i am following for analysis thoughts, personally, i am thinking solder balls, arched a contact,

      • Angel

        I believe its good that this was posted… this help Asus… because if many people post this problem then they can get clues to what the problem is by comparing things…If nobody said anything. then A serious problem might never be fixed… companies might hate bad reviews but in the long run it helps them

      • Ruud Niet

        I do not even want asus. msi or gigabyte in any of my systems at all EVER again.
        The same goes for the Corsair products they make crap and all of them have the worst support on the planet.
        You basically am screwed to buy anything form these D grade manufactors
        I have only bad experiences over the last 8 years with them, time to change to a proper company who is going to give their buyers support as it should.
        These companies are no longer worth buying from at all, especially because they only react if some magazine tester gets active.
        All my current boards have issues and non of them gave me support on the problems i am having.
        Failure to run memory 16/32 Gb memory sets at xmp profiles, usb ports failing and destroying devices.
        Too much to mention, so i am still searching for some manufactor who can replace these crap builders
        I send for instance gigabyte a motherboard which was acting weird and i told them there is something wrong with the northbridge, i had to send it to some address after several months it came back with the message NOTHING WRONG.
        So i asumed these guys should know what they are doing right…… Well WRONG they don’t the motherboard died 3 months later.
        And guess what i found when i took the cooler of the northbridge yes indeed a totally melted chip..
        The same happened with me on a msi gpu they screwed up on that also, yes it blew up they did not even want to talk with me.
        Had to get support from the shop which blamed me for probably have damaged it myself.
        Several weeks later everybody was seeing messages about blowing up parts on that nvidia cards…
        So i totally had it with these bad companies.

    • Isaac Kingsley

      He’s sharing his horror story, if he brushes it aside then nothing will be investigated and if it IS an issue, more people could have their hardware killed.

    • solomonshv

      no, YOU were probably mishandled and dropped on your empty head as a kid. this is not just a random occurrence. this has happened to many owners of this specific board already. write ups like this, and the write up about EVGA’s terrible GTX 970 cooling design, help the consumers make the RIGHT decision and keep the manufacturers on their toes.

  • arkon

    Sh***.the motherboard is still in beta? 😀
    Its not good for asus.

    • James Baranski

      Wrong.There is no proof it’s the boards fault. This could be the users fault, bad PSU, bad ground, bad electric in the home.. Who knows..

      • arkon

        imo I guess its not user fault.its more about mobo fault.will see in time.
        and what if cpu vrm is too hot and crash instantly without a proper cooler?

        • Nathan Kirsch

          James, you can rule out bad electric on the test bench and unless I hit f10 and enter wrong you can rule out user error. You make it sound like we haven’t been testing hardware daily for 12+ years. This was posted as it was an unusual event. It wasn’t a story we even promoted, e-mailed out to our subscribers or anything like that. It was posted up mainly to see if others out there that have this platform are also having issues. If there are I hope they’ll post as we might better understand if there is a greater issue here with the PSU, 1.5V DDR4 kits, the motherboard or something else.

        • James Baranski

          THERE IS NO WAY TO PROVE IT IS THE BOARDS FAULT AT THIS TIME. Unless your a electronic engineer and can scientifically prove one of the components caused the issue……. You get the point…Your readers will get a bad impression on ASUS. You could have bumped the board and hit a solder joint. It could have happened though Fed Ex(Asus uses Fed Ex) Asus will gladly ship another board to you. If you have an issue with the second board, then there is a legit concern. As a reviewer, your should know, these things happen and your write can be misconstrued by readers that they make a bad product. You should know, every manufacturer has had issues like this so trying to prove your a “legit” review site by writing the article is terribly wrong…

        • .halt

          Someone is trying to PROVE that its a design flaw in the MB? How did I miss that?

        • Dave lister

          Get the stick out of your ass – reviewers that take the risk of angering suppliers by publishing faults are the only ones worth reading. Anyone with even half a brain wouldn’t hold off buying one of these boards after Asus / Intel comment on what caused the failure… If it’s a problem two reviewers have had so far, at this early stage….

        • K4te

          “Get the stick out of your ass – reviewers that take the risk of angering suppliers by publishing faults are the only ones worth reading.”

        • James Baranski

          If you tested hardware for 12 years, you should know better 🙂

        • Mysterio

          Quite the contrary, i think they knew better by posting this. I really wouldn’t want to spend over 1k dollars and find out that one of the components had a fault. Alerting the buyer to be aware of a potential issue, that’s the point of the article.

        • James Baranski

          Look, human beings make the board. Users handle it… A solder joint could have been damaged through handling, transportation. PSU’s have been known to fault, power surges, ect.. I guess means you are assuming and this is no representation of Asus, Gigabyte, MSI or whatever board manufacturer. Asus would gladly resent the site another board. To make a write on this issue is dead wrong. If the next board has the problem, then yes. A write would be in order. You do not see sites write a bad review on a Honda Accord if the alternator failed on the testing do ya? Sheesh guys..

        • Nathan Kirsch

          If a brand new car model blew up and caught on fire two weeks after being launched it would make the news. I recall an electric car maker that recently made news for certain fire situations. Thank goodness I live in America, started my own corporation and have freedom of speech. If I lived in some other country you’d likely have me stoned for posting about a factual event! This is why I started Legit Reviews… Because I didn’t believe everything that was being posted on others.

        • David Calloway

          Look, all the man was trying to do was raise awareness to an issue he had with one of the X99 MB’s. If this happens 1 in 10K then that’s fine of course. 1 in 10 then obviously there’s a problem. No blame was assigned. Period. Intel does design the chipsets, fabrication however is handled by the OEM’s. Human beings do handle and to a lesser extent make the boards, but not the solder points on the board. At this point I believe it is a safe assumption that anyone reading reviews for an X99 platform isn’t going to jump ship from their favorite MB OEM because of this review, but will take note and watch. Face it; we’re not Dell or HP people. As far as typos are concerned; your last paragraph should read,’ gladly resend the site… ‘. Yes James, if I were to go down into my garage and notice my ’13 SLK 55 needed a new alternator I wouldn’t think much of it…on the other hand if the alternator grounded out and melted one of my forward wiring harnesses I’d be f**king livid. Automobiles are a poor comparison to add into the mix. BTW most test sites have stable voltage supplies before the PSU….. power surge??? Oh brother…. UPS’s anyone???

        • Rob Ludwic

          I would like to add my two cents to this article. James my friend, Friday morning the 5th, I flashed the BIOS on my ASUS X99 Deluxe and I have done this many times throughout the years. The board had a 5930K in it and a 16 gig kit of GSkill DDR4 2666 Mhz Ripjaw RAM. My board did not smoke but it and most likely the CPU died. The board could not boot and during POST it hung at the CPU LED. This does not sound like an isolated incident with Nathan. He is just telling my story also. My parts are on the way back to Newegg. I paid $55 to expedite it so they can get my replacement parts back to me ASAP. Don’t hammer Nathan unless you hammer me. The only difference is I couldn’t afford spare boards and chips and my system didn’t smoke. The MB and most likely the CPU died. Isolated? I think not.

        • Nathan Kirsch

          Rob – Did you happen to take any pictures or see the point of failure? If you haven’t sent the board back yet I’d be highly interested in seeing if you could figure out if a component on the VRM failed.

        • Johnny

          I also have just had this same issue. Running the 5960X on a X-99 Deluxe w/ Corsair 2800 Dominator Platinum and an EVGA 1000P2. I had the system on stock settings and was running smoothly. It happened during a restart and hung on a black screen and now the LEDs on board and fans flash but that’s it. I have a RMA in the works with Asus (great customer service experience here) but I got impatient and thought it only being the board that was dead, I picked up a MSI board and a Patriot 2400 kit; and had the same issue, hope I didn’t damage this board. Gonna head out tomorrow and get a new CPU and maybe a board. Luckily I have gone overboard and built 3 computers lately and I can just fall back on my Z97 SOC Force and 4790k or MSI Z87 GD65 and 4670k. I do know that with the little time I had with it the 5960x, it rocks and I will have two setups when this is all over I just don’t know if I am going to keep the MSI board as I really wanted the RVE, it was just out of stock today. Thanks for the article as I am now sure I did nothing to provoke this issue.

        • oldbat

          the board caught on fire for another reviewer.

  • Christopher R

    I was considering upgrading in November/December. News like this make me wonder if I should wait until the new year, maybe overclocking isn’t the wisest thing to do this early in the game on this board ?

  • Tom Servo

    I thought ASUS’ fancy OC socket would be able to bypass the FIVRs? Did you have it enabled? Sounds like an excellent case for its existence, since it’d spread the current over multiple inputs (i.e. the additional pins).

    • Nathan Kirsch

      The only thing alerted in the BIOS when things melted down is the G.Skill XMP profile for the memory kit. Everything else was not altered. I have attached a picture from the UEFI that shows the settings.

      • Tom Servo

        ASUS reverse-engineered the purpose of the additional pins on the CPU, and it turns out that you can override the FIVRs and supply the appropriate voltages externally. I’d wager by doing that, you’re spreading the amperage via different traces than all over the standard VCCin and probably also let the mainboard load the VRMs more evenly.

        However that OC socket option needs to be turned on manually, it’s off by default (from what I’ve read, anyway, still waiting for prices to settle before buying into Haswell-E).

        I’d figure it’ll be a nice option to have, when going with things that are outside of the standards, like the 1.5V RAM. If you get the board back from Asus, I’d look into enabling the OC socket.

        • Nathan Kirsch

          I have multiple X99 Deluxe boards and 5960X processors, so I’m back up and running now (how I got you those screen shots). From my understating the ASUS OC Socket automatically enables when the board is overclocked and is off when the processor isn’t. ASUS isn’t saying what parameters enable it.

        • Isaac Kingsley

          Just casually having a few X99 and Extreme chips lying around, I envy you right now.

        • prices to settle? you mean ddr4 or maybe the mobo. Those intel prices barely move

      • Dennis McCarthy

        I see 1.35V there for the XMP not 1.5V is the 1.5V a miss print or did you force it beyond the XMP voltage profile?

        • Steam

          I believe he said the HyperX works on 1.5
          not the g.skill

        • Nathan Kirsch

          Correct, the HyperX Predator Kit is XMP set to 1.5V. The G.Skill kit used right after was set to XMP settings of 1.35V.

  • medo

    Hard to say, too many variables :

    *DDR4 new voltage
    *new x99 platform
    *new Intel CPU with 6-8 core 140W

    I dont think companies like ASUS and MSI, that create mobo for AMD platform that have CPU can reach 220W, would cheap out on expensive mobo, and there internal Q.A testing wouldve caught something, also they would test many Intel CPU, however the only thing they cant predict, is what the consumer will use is RAM

  • Arb

    ASUS VRM’s failing again.. who would have thunk?

  • Homey

    that’s terrifying to read as I’ve purchased the X99 on the 1st of the month but yet to source the ram so it’ll be long after any supposed DOA terms before I can insert the ram and pray the thing doesn’t self destruct on me. Sorely tempted to drop from my aim for 2666 or above and go with 32 gigglybitz of 2400mhz now…. can’t wait for more info n updates to this thread…. negative news it may be but I thank you ever so muchly for the information nonetheless.

    • Tom Servo

      The higher clockrates on DDR3 made neglibible differences. I doubt it’ll be too different with DDR4, so going with 2400MHz for safety/reliability reasons isn’t unreasonable.

      • Homey

        thanks for that Tom (nothing worse than reading threads that are mere “Venting” of negativity, personal gripes and preferences)
        and as with everything these days… so thanks for the bit of positive feedback…. which is WHY this site thrives after all
        built by human beanies, utilised by the same etc so who knows.
        Besides Giglybits didnt make a comparitive board in their black range (tested for over 160 hours etc).
        I should’ve added my rig is for 20 HDD’s incl couple of M.2’s and totalling over 60 terriblebitz of data, 24/7 use frequent accessing to n fro.. Photoshop and dabbling with Auto Inventor etc oh and NO GAMING (unless I find an emulator for Space Invaderererz..heh heh)
        Would you say 32GB (4x8GB) of 2400MHz more than sufficient for now and future use (as I can simply lob in and double what I’d have?

  • Coach

    Things like this are difficult to identify since you’re using so many new components in these tests. The only proven component was your PSU. Personally, I’m thinking it was the mobo, but I’ll be following this to see. What a shame. 🙁

    • Nathan Kirsch

      Exactly and there is no way to figure out here exactly what caused it. Corsair and ASUS have been great at offering help and both companies will have their products back on Tuesday for testing. Hopefully we will be able to figure it out. Right now I got the same general setup (with a new board, CPU and a Corsair AX1200 PSU) up and running just fine for the past 10 hours or so.

      • James Baranski

        BTW I have used Corsair AX PSU’s with 1 of them failing.. Just saying..

      • Legitsu

        tom is right on with the solder ball point
        in addition to the point of the flux burning off there is also the fact that VRM’s get pretty fking hot more then hot enough to cause the solder to “melt” enough to cause a short if its physically close enough
        shotty solder work on ASUS’s part .. nuffsaid

  • Damion Bacchus

    thank you….. Asrock x99m killer it is,was gonna wait for the gene but ……..on another note could it be this new vrm design that Asus is bragging about, it is still in its infancy stage?

  • Kirk Martin

    I am slowly going off ASUS tech, they seem to be, well incompetent. Not only did my Asus mainboard keep saying I had a surge, and kept shutting down… I have gone through 4, yes 4 XM299Q monitors, just to get a working one. So this really does not surprise me at all… I have gone over to Gigabyte mainboards, I love what they have done with the bios, making it easy to use, with mouse control also… Really nice touch. And I have a performance boost, just from changing the mainboard, of my system. 😉

    • Jason

      Kirk, this bios with mouse control you speak of is called UEFI, all boards have it now. Don’t give Gigabyte too much credit. Asus still make the best boards on the market hands down.

      • Kirk Martin

        That might be so, but there customer service is pretty bad, had the pleasure of getting in touch with them over the last few weeks, and they did not want to know… So they lost another customer.

          Asus and ASrock share technology. ASRock is owned by Pegatron….

      • Isaac Kingsley

        I’ve always used Asus boards and recommended Asus boards to people asking me about new builds, the build quality is generally pretty good. Their customer service sucks (from my experience), although i’m not to sure if it was the supplier messing me around. Had a chip burn out on me to be told ‘Theres a burn on one of the chips that has voided your warranty’, The burn was the reason I was RMAing the board.

        Recently switched to an MSI Gaming 7, so hopefully they live up to standard 😀

    • Jon Ghosty Carr

      I have used a number of motherboards in my time and I have used Asus boards and they are not all that never had one fail though, but I had my last board which was a Sabertooth 990FX which is meant to be the best AM3+ board, but i switched to a Gigabyte board the 990FXA-UD3 better features better for overclocking, asus are over hyped …….

        FWIW (I build a lot of systems for a charity as well as for friends, family and coworkers) I have used Gigabyte exclusively since a very bad experience with Asus 15+/- years ago. This
        X99-Deluxe was my first Asus board since then, and it happened to burn up and take my CPU with it at 8 weeks. And I agree about the 990FXA-UD3 (I am using one of those on a backup system now and I love it – stable as a rock and just keeps going no matter what.)

    “Our worst fears were reassured.” People need reassurance, not fears. I think you mean your fears were confirmed.

    • I would imagine that reassuring your worst fears is actually correct because now whenever Nathan boots up another X99 Deluxe, the thought goes through his head for a split second: “Am I ruining another $1400 worth of hardware by merely pressing this power switch?”

    Interesting…I wonder if you tested other X99

      Our motherboard reviewer (Dan Stoltz) is testing EVGA and Gigabyte boards right now. MSI never sent us anything.

        I wanted to buy a x99 system but after reading this article and comments…
        Should i wait until asus or corsair give a clear answer for this issue?
        Is it possible this problem will happen in a normal situation( not in overclocking mode)

      The Phoronix article was tested with a completely different motherboard. MSI vs. ASUS.

  • That sucks! I really wonder if the memory voltage might be an issue, since the memory controller is on the CPU. DDR4 is designed for what, 1.2V? And the Intel specs show 2133MHz as being the designed speed for these CPUs… so maybe pushing that to 3000MHz and 1.5V (almost 30% and 25% higher than normal, respectively) is just too much? If so, it would reinforce my personal preference for standard speeds of memory. The tiny performance differences from high performance RAM is not worth this sort of risk 🙂

      For what it’s worth, the tests I did (Michael Larabel of Phoronix) were at stock speeds. This was my first time powering up the board, stock everything.
