AIDA 64 and Sandra Memory Bandwidth Tests

AIDA64 Extreme Edition 5.80 Beta:

AIDA64 Extreme Edition 5.80 software (websiteis an excellent benchmarking tool for looking at memory performance on any desktop PC. This version of AIDA64 implements full support for the upcoming Intel Skylake processors, adds advanced support for Microsoft Windows 10 and Windows Server 2016 operating systems, and supports the latest graphics and GPGPU computing technologies by both AMD and nVIDIA. AIDA64 Extreme 5.80 software is free to try with limited features or $39.95 to buy with 1-year of free updates. 

Benchmark Results: Using the slowest DDR4-2133 dual channel memory kit on the market we were reaching just under 33,000 MB/s of read/write memory bandwidth and by the time we got up to DDR4-3200 we were running over 46,000 MB/s! The write memory bandwidth went from 32,263 MB/s to 46,250 MB/s, which is a 13,987 MB/s or 46.4% increase in the effective write bandwidth. The performance increase was found to be fairly consistent until the very end when we loosened the memory timings to better match that of most 3200MHz memory kits on the market today.

Benchmark Results: Using the AIDA64 v5.80 copy test we found similar results, but we did plateau at the very end when we raised the memory timings. We started out at 30,882 MB/s with a DDR4 clock frequency of 2133 MHz and ended up at 41,086 MB/s with the DDR4 3200 MHz memory kit.

Benchmark Results: The latency of the memory decreased as the DDR4 DRAM clock speed increased despite having to loosen the timings in the UEFI along the way. At DDR4-2133 we averaged 95.4 ns and then improved that as the clock speeds went faster until we reached 76.4 ns at DDR4-3200.

SiSoftware Sandra 2016 SP3:

Benchmark Results: Using Sandra 2016 SP3 we again checked the memory bandwidth performance and managed to go from 27.1 GB/s with our 2133 MHz DDR4 memory kit with CL12 timings all the way up yo 36 GB/s with the 3200 MHz DDR4 CL16 memory kit. Sandra 2016 SP3 showed a 33% improvement in memory bandwidth for the AMD Ryzen 7 1700 processor overclocked to 4GHz on the MSI X370 Xpower Gaming Titanium motherboard.

    Could somebody please tell me how many MHz on a memory can I run with Ryzen 5 1400? I’d like to buy a DDR 4 memory of preferably 2666 MHz, but if I can’t do that I could also do 2400 MHz. Will my processor be able to support these two memories? I’m anxious because the article on R5 1400 said it supports ‘anything under 2667 (2667, not 2666), while another source said it only supports 2667, and some other numbers of MHz, but none of these were 2666.

  • Vader 23

    CPU: Ryzen 5 1600
    Motherboard: Asus B350 Prime Plus
    Ram: 16GB (2×8) DDR4 G.SKILL Ripjaws V (F4-3200C16D-16GVKB)
    Running the latest BIOS update, still can’t run my Ram above 2133mHz.
    Any thoughts/help?

    • Amet Monegro

      Update BIOS to AGESA 1.0.0.6 (beta BIOS, avalible on Techpowerup RYZEN BIOS issue) if problem persists change your RAM for modules on compatility list, luck

  • Jaan Doh

    Well I’m of those who got stuck with DDR4 RAM that is not compatible with my motherboard.

    I always used to think RAM was all about timing,
    I’ve updated my bios 5 times from 1.0 right the way up to 1.5
    and still my memory does not attain the speed it was advertised as being capable of.
    The most I can can get without messing in the bios (messing because I don’t know where to start).

    Motherboard: MSI X370 Carbon Gaming Pro
    CPU: Ryzen 7 1800X
    RAM: 32gb (2x16gb) Corsair Vengeance LPX DDR4 3000Mhz (cmk32gx4m2b3000c15)

    I ran typhoon burner and it tells me the chips on the RAM are Hynix H5AN8G8NMFR-TFC (M Die)

    Has anyone had any luck with these?

      Try Vsoc at 1.30/1.35V, with VLLC in high (3), this is diferent between bords brands.

  • 509dave16

    @nathankirsch:disqus Were you able to achieve 3200mhz with the Corsair Vengeance LPX CMK16GX4M2B3200C14? Haven’t been able to determine if this model is using a Samsung B-Die or SK Hynix.

  • Game Story

    Sorry guys, i dont understand. Please help, what kit of memory works normal (with 3200mhz) on msi MB? Becouse i order Corsair Vengeance LPX 16GB (2x8GB) DDR4 3200MHz Kit – (CMK16GX4M2B3200C16) In this test they use the same, but i cant understand does it work in full power or just on 2400?

    • Wesley Sidney

      they used cmk32gx4m4b40000c19

  • Lex –

    Interesting post and conclusions, however there are a couple small errors.

    Only DRAM timings available are TCL,
    TRCRDD, TRCWRD, TRPT and TRAS. The only way to affect sub-timings is by
    lowering your DRAM ratio (essentially behaving like strapping) and
    increase reference clock. For example at 2400 ratio TWCL=11, at 2133
    ratio TWCL=10 and at 1866 ratio TWCL=9.

    Most CPUs have a memory “hole” where it’s unable to train memory
    from 3350-3450 MHz up to 3500-3600. This means you might be unable to
    run 3400 MHz DRAM frequency but 3600 is OK.

    This is true on some boards and chip set but not all of them. The RAM timing you can adjust is a function of the BIOS and control logic more than the CPU itself. Not every manufacturer will give you ever single little timing parameter to adjust. However, it is true for the board you were using that not everything is available for you to tweak.

    The timing for bandwidth and CAS timing are also a limit of the passive components your system, too, it’s not just the CPU directly driving the memory. If you get the timing ratios wrong in your system it can become very unstable, however, if you do it correctly, the default (pre-programed XMPs) will be faster but from that, you can further tweak it to give you an additional boost. Manual tweaking on this platform is beatiful, if you know what you’re doing or hell, if you don’t.

  • Danny Royer

    I paid 250 USD for 32GB of CORSAIR DOMINATOR SERIES DDR4 @ 3000MHZ only to figure out that it refuses to clock above 2400MHZ (Yes I know it is technically 2311) with Ryzen 1800X above stock clock! Supposedly the memory was ensured to be compatible. So now I am running the vengence 3200 and it works wonders. @ 4.0GHZ with 3200MHZ vengence. Life is sweet! This is with the TITANIUM and ASUS ROG CROSSHAIR VI

    • Ryan Scott

      Did you do 2×16 for your ram? Or was it 4×8? Mind sharing a link or model #?

  • Isaac Sandoval

    Very helpful. Thank you for doing the leg work. Ordered some new modules.

  • Samoreye

    Please help. My computer will not boot up on two sticks of 4gig memory speed is 2100. If I leave one stick of 4gigs it’ll work… but two sticks will not let the computer boot at all… nothing on screen. I also tested to make sure each ram stick worked by replacing and they work just fine on their own. I also made sure they are in the correct position 2 and 4. Still nothing. Updated bios as well.

    • mvtoss

      If you tested each stick separately, it’s probably the motherboard slot then.

      • Samoreye

        Possible. I decided to just run them as single channel. Still got 8 gigs and the speed I desire. It’s all good for now. Thanks for the feedback.

        • Matt

          What do you mean run them as single channel? Did you try the other two slots etc? You can also do full memory tests.

  • marco

    I think this is is just related to this particular mother board.
    A few days ago I read somewhere that a guy got a Quad channel 64GB gskill kit for x99 working on a gigabyte board working at around 2600mhz at cl13 with 4 sticks and two of those sticks at 3200mhz on an early bios.
    I will try to find it and post the link here.

  • Paul Sattler

    I am looking at either an AsRock X370 Taichi or X370 Pro Gaming mobo (when they are in stock again…) and I will NEED 64 GB ram so a total of (4) 16 GB sticks. So you guys are saying the max I can get out of ANY 64 GB DDR4 is 2133 regardless of rated speed on the memory? If i bought a 3000 or 3200 memory, could I at least be hopeful that this will be fixed in a future BIOS update without having to get a whole new motherboard later on??? Again, i need to run 64 GB of DDR4, for what programs I am running I don’t have much choice.

    • Oliver Törnroth

      I´m quite sure that you´ll be able to up the speed in the future with BIOS updates, it´s just that the BIOS:es need more updates to support faster ram.
      Look at this ama with AMD:

      http://www.tomshardware.com/reviews/amd-ryzen-ama,5018.html

      Seems to be possible if there is no hardware limitation, and with you going with a x370 board I would think that there is a high chance of increasing the speeds.

  • SKD007
    • Paul Sattler

      Do you have 4 x 8 or 2 x 16 memory sticks?

  • Kilgore Sixsixone

    I’m thinking of going for the 1800 with 64GB RAM. How much of what is said in the article carries over to a system with this spec? I am new to overclocking but not new to building a PC. My guess is that an 1800/64 system not what was tested so it says nothing at all about what I might expect from an 1800/64. True?

    • Lex –

      Unless you’re a developer like me or, doing game modding in CryEngine, are an architect or are editing very large projects video projects, don’t bother with anything beyond 16 GB.

      • Kilgore Sixsixone

        I’m making gigapixel panoramas by stitching thousands of images together. 64GB is nowhere near adequate so in addition I will need a couple of 1TB M.2s. FWIW it seems the Ryzen is not stable enough yet with all 4 memory slots filled. Yes, people have got them working but PC builders have their doubts. I haven’t checked for a couple of weeks but PCSpecialist and OcUK were not offering 64GB Ryzen builds. As I want my computer now, I’m going with Intel – then I can have 128GB 🙂

        • Lex –

          Sh*t.. If you’re doing that, yes, by all means go with Intel. Xeon CPUs even.

          The Ryzens shine when you take it out of auto XMP mode and go full manual, of course this means you reall have to know what you’re doing. It’s a bit different than the previous AM2 ~ AM3+ clocking. If someone picks the wrong ratio throughout the system, that will really hurt performance, in some cases it will crash outright.

          If you’re doing that kind of work, look for boards that support 256 MB RAM and get that amount. The problem with the way the hardware is designed and how the memory manager in many operating systems work, including Microsoft Windows. If you get a strange size, that can negatively impact performance, even if you have good, tight timings.

          It goes a little bit like this;

          Good memory sizes; 1, 2, 4, 16, 64, 256, 1024 (1 TB)

          Bad memory sizes; anything that doesn’t match the above specs., including 32, 36, 72, 96, 112 and 128 GB.

          If the application is heavy on the CPU and memory, which it would be obvious, if you need that much memory, getting memory with a very low CAS timing is advisable. One thing about the newer Xeons, they don’t like getting their memory clocks pushed past 2400 MHz, it can cause instability in the system. There are some nice 2400 MHz CAS 10 modules out there in DDR4, depending on the type of board you get you might be able to get it up to 256 GB of it, for which the Xeons won’t have trouble clocking at that speed nor timing wise.

          I wish you luck in finding a decently priced system, however.

          If you’re not already on pcpartpicker.com, you might want to join it. So you can create your ideal hypothetical system, then price out the parts. If you need help, just ask the community, I’m on there as well.

        • Kilgore Sixsixone

          Thanks for that. I use partspicker and I have been on OcUK and PCSpecialist with my problems. Price is of course _the_ problem.

          After agonising over the pros and cons of AMD/Intel, Intel K or X and single or dual processors, I had more or less decided to throw caution to the winds and commit to a o/c 6900K on a Taichi board (only one with true dual M.2 AFAIK) and then I found out about X299. For my app, cores rule and I was already pushing the boat out by going for 8 rather than 6 cores. But now there is the possibility of getting 10 cores for less than the exorbitant price they are asking for a 6950X. Doh! That’s put all my plans back 6 weeks. But then there never is a good time to buy hardware is there? 🙂

          I notice we are well off-topic. Is that a problem here?

  • Nathan Benfield (Nate’s Days)

    Okay this is helpful. BUT what about DDR4-3200MHZ @ 16-18-18-38 ?

    • Lex –

      3200 MHz CAS 16, is a big waste of power and you’re not going to get a really good snappy system. High bandwidth is pretty worthless without a system that can react to user input in a timely matter.

      Try either DDR4-3000 MHz @ 13-13-13-35 or 3200 @ 14-14-14-34. The 3200 in this case will be slight faster than the 3000 but the 3000 will have more snappiness or react faster to change in input.

      This is purely subjective though, not every motherboard can use the 3000 MHz RAM. Hypothethically speaking, if you motherboard could handle the 3000 MHz RAM and you’re a competitive PvP gaming player, the 3000 MHz would give you a slight edge over ther 3200. If you’re not concerned with absolute lowest input lag and of course reactiveness of your system, then go with the 3200 MHz.

      I suppose you wonder why I say the 3200 MHz CAS 16 is a waste of power.

      It has to do with the raw bandwidth you are paying for vs. the actual bandwidth you are receiving.

      An example; 2400 CAS 12, 2600 CAS 13, 2800 CAS 14, 3000 CAS 15, 3200 CAS 16, 3400 CAS 17, 3600 CAS 18, you might notice a pattern. If you divide the operation speed by the CAS you get 200. The number 200 is of “average” performance. If you get under 200, you’re wasting power, wasting time, etc. If you’re over 200, that’s a true performance profile.

      What I’ve noticed is every 25 points above 200, you get noticable gains in gaming, for every 10 points above 200 are noticable gains in rendering and anything that is CPU and memory heavy that doesn’t require much or any user input.

      Simply put, a lower CAS than average performance will make you happy upfront and down the line. CAS timing doesn’t use more power if you tighten them regardless of your operation speed of your RAM. The higher you clock your RAM, does use more power. A lower CAS timing with a faster RAM means you get more of the bandwith your paying for (out of the wallet / purse) and down the line in the power bill. Having the correct timing on your RAM basically allows you to better utilize it capability, it’s not just the operational speed of the RAM you need to worry about.

      With the new BIOSes in place on both Intel and AMD, the 3200 MHz CAS 14 is well tolerated, not to mention quite useful. I hope this helps.

  • YOUDIEMOFO

    Hopefully in year or so I will have been able to say that I have built my first Ryzen computer. Getting those BIOS revisions out of the way and hashing out any and all performance issues is what I am looking forward to.

    Can not imagine building a hexacore-plus system for under $900… Then again I might bite on their HEDT system configuration if performance is all there…..mainly for gaming, but of course everything else I like do as well. Love the capabilities of a PC…..

    • Lex –

      You are wise to wait. You might be able to make it under $700, if Intel drops the price of their chips to become competitive again. Which in turn AMD will drop theirs. It will be a win-win for the consumer.

  • Neon Warge

    Price difference between 2133 vs 3200 is small? This is bull$sh1t. FALSE. At least in our country it is very expensive.

    • Lex –

      How much of a difference is there between 2133 and 2400? On Ryzen, 2400 MHz aren’t overclocked and don’t need a BIOS update. Perhaps look at 2400 MHz CAS 10 or 11? That’s a pretty snappy system, good for gaming if you have a nice card.

  • zolo111

    I just grabbed an R7 1700 and will buy a Gigabyte AB350M-gaming 3, I’m building a 3ds max design, Photoshop, rendering machine.

    I’m looking to buy a 2X16GB kit, most likely not Samsung & not Single Rank 🙁
    since it’s almost impossible to find online.

    Would a productivity machine ONLY (no gaming) suffer from a lower speed, Dual Rank RAM? There’s almost $40 difference so I was wondering., thanks!

    • Jonathan Phoenixreborn Shearin

      Nice sounds just like my build

    • Lex –

      Speed isn’t everything on the RAM, CAS timing has a lot to do with it if you’re doing rendering. Anything CPU and memory heavy will bare this out. You’re better off getting a lot of memory for the render station, stay at 2400 MHz and CAS 11 or 10. The gaming system, depending on PvP or not, low latency needed for PvP but if you’re not a highly competitive player or don’t it for living, a higher bandwidth w/ 16 GB RAM installed should be fine, if you want a bit of a perk, getting low latency high bandwidth memory should make you happy.

      The single and dual ranks were a problem on other platforms and can be a problem with the auto-tune XMP settings for AMD Ryzen. If you’re serious about getting speed out of that computer, you need to go full manual. That’s a lot more work on AMD platforms than on Intel, just want to give you a warning.

      • pillybilly

        Blah blah blah… If someone needs 64gb, is this possible on a ryzen system or not?

        • Lex –

          Yes, 64 GiB is possible with this system chipset. You have to check with the manufacturer on the specific motherboard models that support it, some only support up to 32 GiB.

          The unfortunate thing is, most motherboard manufacturers and their BIOSes with hardware will only support 64 GiB @ 2133 MHz. I’ve seen some people actually get the
          RAM up to 3200 MHz but I’m unsure of it’s stability.

          For the motherboards that you want to use 64 GiB on, the vast majority only accept 16 GiB by 4 modules, instead of 32 GiB by 2 modules to make 64 GiB RAM installed.

        • pillybilly

          Ok thanks, i read some producer allow 4 modules at 2666Mhz but i can’t find anyone confirming this.
          Anyway i am not interested to overclock , i need a stable platform running at default speeds.

  • Bojan Susic

    I’m waiting to see BIOS updates and ddr4 ram speeds over 3600mhz..Faster ram will put Ryzen closer to i7 7700 on 1080p gaming performance. On Intel platform going over 3200mhz makes no difference…Going from 2133 – 3600 is almost 20% boost in 1080p gaming in theory…

  • seansplayin

    16GB Corsair Vengeance LPX 3200 would not post above 2933 until I raised the Dram voltage. Placed at 1.5V and now runs great! 1800X is clocked to 4125mhz at 1.5Volts with timings below stock at 16,16,16,36.
    for comparison the techreport ran Y-cruncher and AIDA64. I can pretty much Tie the Memory Read, Memory Write and Memory copy of the I7-7700 and I’m only 3 seconds slower in Y-Cruncher at 259 seconds. The Tech report showed Ryzen at 299 seconds when running 2133mhz memory.

    note: all tests were performed at 4ghz so probably will go up if I retest now:)

    • Tyrann

      I almost feel that Ryzen is for the enthusiast crowd because of how much tweaking you have to do yourself lol. Great job btw, what motherboard and memory kit are you using? They said memory version 5.39 for corsair but i dont know where it would state that

      • Antonio Amigo

        It’s new, and building your own system is always like that if you actually want to the value for your buck. You don’t have to tweak settings if you’re not to picky about getting the most for your buck. Just thrown in your cpu/ram/ssd/video, install drives, update mobo bios and away you go. It’s likely that 60-70% of the people who own computers are running them slower than optimal.

        The thing is that you can get substantial gains from tweaking and that’s the same most hardware and also this is a enthusiast website. Most people are afraid to tweak stuff, but really all you do is restart your computer and try again. it’s not a big deal…

        • alan

          totally agree. free gain for nothing. why not.

      • Lex –

        Actually, if you get a good board and an update to date BIOS for that motherboard, your set. If you want to go manual, that’s an option, too, if you’re brave.

    • Lee The Bee

      That’s a worrying CPU voltage.

  • Djura Figura

    This needs testing in CS:GO and Overwatch on the lowest setting for MANY players who are playing on LOW for the highest possible FPS in combination with 144+Hz monitors.
    You won’t get any GPU bottleneck this way for sure.

    • Scott

      Yeah i was dissapointed by the number of real world game benchmarks. Would be nice if the update or make a new article with ryzen 5 and b350. As this is where the majority of sales will be. Atleast in gaming. Ryzen 5 in essentially the same with cores locked so id wouldnt see why it would be any big different. But would be nice to see if there are any meaningful differnces in b350.

  • Greg Bryett

    Ugg, I have the MSI carbon pro and I am not able to take my Ripjaws V 3200 past 2133 without crashing back in to the bios!!! On the plus side my 1700 is running at 4.1ghz at 1.3875vcore 🙂

    • Petrovic Petar

      This is a well known issue right now, as technology support progresses it will get supported.

    • Tyrann

      they didnt officially say it can get that high on OC for the MSI carbon pro like they did with the Asus/Gigabyte/Asrock X370 high end models. Maybe they’ll update it but i did see they’re releasing more models from MSI.

    • Greg Bryett

      2933 is still the best I can get out of my 3200 MHz memory, even with the new bios that MSI released yesterday. Waiting for some feedback from their support. 4.1ghz is so far stable on my 1700, which is an outstanding result at 1.3875vcore. Under water and after 60 mins OCCT 64c.

      • Nathan Kirsch

        That is a great overclock. Are you populating all 4 slots as that could be the issue.

        • Greg Bryett

          Thanks Nathan. Only 2 slots filled. I have tweaked my ram timings as I can’t hit 3200 at the moment, so instead of Cas 16,16,16,16,56. I have Cas 14, 14, 14, 14, 30 at 2933… Best of both worlds. Just re-installing a clean versions of Win 10 for some testing.

          I updated bios to 1.3 which includes the AGESA 1.0.0.4a update and can now run ram at 3200 as well as use A-XMP in bios properly. Try this. Also it is clear that currently Samsung ram works better than Hynix. I dialed back my overclock to 3.8ghz 24/7 using 1.2875vcore. Seeing good results.

  • Ben Kanban so well

    Excellent Article clarifies in great detail the true needs of Ryzen. It appears that 2933 and tightest timing you can find do the most diminishing returns past 2933 but if you break in to 3200 then its all CAS. I wonder if Zen2 will fix this limitation.

  • Marcin

    My 5-years old Core i7-3930K with Quad DDR4-2400 has 63000MB/s (read) and 65000MB/s (write) in AIDA64 🙂

    I’m using 4x Corsair Vengeance CMZ16GX3M4A2400C10 DDR3-2400 10-12-12-31 CR1

  • YOUDIEMOFO

    Still not seeing this DDR4 beating out my DDR3 2400mhz Cas10 when this stuff screams by with 65-55GB/s reads/writes, or whatever it can exactly do as this is off the top of my head…

    Maybe I’m missing something??

    • looncraz

      Yeah, it’s hitting these levels of performance with just two channels.

      • YOUDIEMOFO

        One more reason to not want to upgrade to something lesser. Still not sure why the hell AMD launched their newest hardware having these limited abilities to something that has been available for over four+ years…. Quad channel memory…. There has to be incentive…..other than a cheaper price point for someone to truly want to jump ship.

        Although if they can get the competition to lower their prices their actions could be successful in other ways.

        • Tyrann

          cheaper price point is #1. lets build an 8-core vs 8-core machine from Intel and AMD and see what the end cost is for both machines. Then compare benchmarks and you’ll see how minuscule the differences are to justify the huge price you pay for Intel.

        • YOUDIEMOFO

          and then lets talk about “capabilities” of those compared systems….. because Intel blows AMD out of the water for that reason alone. Intel motherboards alone are a reason to go that route to begin with.

          Maybe if AMD wasn’t resting on their thumbs for the last few years their motherboards would be comparable. So yeah…..the CPU and price point says a lot, but when you get what you “pay” for then I guess it is all just opinions from then on.

        • PC Master

          The fact that AMD, a much smaller company with significantly less R&D budget has managed to produce a CPU that’s competitive with Intel’s 8 core offering in mutlithreading at a more attractive should be commended.

          Also it just goes to show how long Intel has been sitting on their laurels.

        • YOUDIEMOFO

          Just goes to show when a company puts a price tag on something….doesn’t mean it is worth it. Choices are good…especially for consumers.

          Smaller R&D budget comes from their shortcomings of a company over the years. They didn’t have to put out inefficient garbage in the past that was obviously a shot in the dark for their CPU department. Not to mention that they have their GPU/APU departments that were sucking up their valuable resources/time over the years. Which we all know has been a sorry excuse

          And to say Intel have been sitting on their laurels is a joke as they’ve done nothing BUT scalp the market with no competition in sight. Still boo to AMD for allowing it happen….

        • PC Master

          “Choices are good…especially for consumers.”

          The only thing I agree with what you’ve said.

        • Darkside

          RIP INferior fangirl, AMD is kicking INhell`s a$$ now, and every re7@rded fanboy….
          for 330$ 7700K vs R7 1700,

          intel suck in every aspect, + they say to consumers, not OC K processor HAHAHAHAH….

        • YOUDIEMOFO

          We will see when apples to apples truly comes out.

          I am an HEDT consumer, so nothing that have dropped as of late has my true attention. Especially this dual channel RAM support. I care not to take a step back in the hardware production route as I’ve been happy with quad channel ddr3 for quite some time now.

        • Darkside

          Hahahah and you call that an argument ? The dual channel controller of the AM4 series is better then the intel`s dual channel + the quad channel is about the same as the dual channel… + AMD will have quad channel on HEDT Thread Ripper and octal channel on the Naples……

        • YOUDIEMOFO

          When things come to fruition then yes I’ll see something, but if you’re going to pump your chest while beating on it just by reading some paper then you could be in for some (hopefully not) disappointment.

          I just would like to see some “price” competition heat up between the two companies. It does sound interesting AMD’s newer hardware to come out, but it isn’t out yet and we all know how rocky the launch of their most recent iteration went…..a little rocky. Things are now panning out better for them, so I am happy about that.

          And their HEDT is about the only thing I’m interested in. Especially if they have monster amounts of PCI-E lanes available for all the wonderful peripherals needing to take up that precious space… Along with monster support for them multiple GFX cards I love so much!

        • YOUDIEMOFO

          Maybe?

        • pillybilly

          You got an intel 7820x for 100$ more than a 1800x, a MB is 100$ more. So at the end you pay less than 200$ but the 7820 is better, faster and it can handle 128gb without any problem…

        • Tyrann

          While the 7820x is the cheapest 8-core Intel has atm, the 1800x is not AMD’s one and only. Pit it against the 1700x or even the 1700 and the price gap deeply widens while performance only slightly decreases. Also AMD benefits much more from faster memory than Intel. But yes Intel is still slightly faster all around.

        • pillybilly

          The only decent price/performance intel is the 7820x then there is threadripper but a motherboard is more than 400$ and 300$ dollar more for the cpu and a 180w tdp means a decent and pricey liquid system…

        • looncraz

          Because quad channel is crazy expensive to implement on a mainstream platform. Ryzen is mainstream, dual channel is mainstream.

          And quad channel only rarely helps performance in any event.

  • Bhavin Mistry

    @nathankirsch:disqus Would G.Skill Ripjaws V 16GB (2x8GB) DDR4 2400MHz Kit – F4-2400C15D-16GVR work with any AM4 motherboard such as Gigabyte AB350 Gaming 3? This particular model says it is for z170 boards.

  • Terry Perry

    The boards are not ready yet and these Chips are for 4K not 1080p this Monster CHIP was made to Run and it just being held back. Plus Intel has said NEXT YEAR EVERYTHING WILL CHANGE. All NEW Boards and NEW and Different S.S.D. plus ALL NEW RAM. Intel is Coming Back. Will CRUSH A.M.D. Again. I just pick up a 6350 6c. with Wraith cooler for 70$ have it at 4.2

  • Am4Guy

    Hi, what is the best RAM configuration for 24GB at the moment (frequency, SR or DR, timing, etc)? Why is 2x16GB the worst configuration, and why we cannot achieve more than 2133MHz with 32GB RAM?

    • Am4Guy

      @nathankirsch:disqus The above question was for you 🙂

      • Nathan Kirsch

        It just has to deal with how the new memory controller in Ryzen works and the current state of the uCode in the UEFI. Right now the platform is not fully optimized, but also shows poor dual-rank memory module support at higher clock frequencies. Samsung IC’s appear to be doing the best on this platform on single-sided modules. That could change in an instant with improvements in the UEFI, so for now single-rank 8GB modules with Samsung IC’s would be ideal.

        • Am4Guy

          @nathankirsch:disqus It seems SR (single-rank) in general are better. In that case, 8 GB SR x3 or x4 would be your recommendation. How about frequency, for example, if I get 8GB SR that has 3000, 3200 or 3400 Mhz, would they all work at that frequency when we have 24GB or 32GB, or will they default to a lower frequency? I read that the Gigabyte Gaming 5 board has support for 3000Mhz+ DDR4 RAM right now with a new BIOS update.

        • Am4Guy

      Tim – MSI has not released 1.22 yet to the public. It’s just an internal beta build for the time being that has been also given to media for reviews.

  • Steven Miller

    This reviewers is really bad if they think AMD designs UEFI on motherboards.

    • Steven Miller

      “it is just a limit in the base UEFI code and that it is not a limitation of the memory controller design or the overall Zen architecture” meaning that the motherboard manufacturers are restricting memory not AMD.

      • Nathan Kirsch

        Sorry, but you are the one that is confused with how this works… AMD is the one that releases the uCode that the motherboard manufactures need to then implement. AMD held the uCode for until about two weeks before the launch and then blamed the board makers for the performance shortfalls. Surely, you heard about how so many reviewers had UEFI issues on the launch articles this is why. The base UEFI code comes 100% from AMD and this is why every single X370 boards memory strap stopped at 3200MHz (it is a hard memory strap limitation they put in the base code).

        • Zurran

          Amd does not release any uefi code , neither does intel. All of that is done by the AIB manufacturers

        • Nathan Kirsch

          5 months ago I said this: “AMD is the one that releases the uCode that the motherboard manufactures need to then implement.”

          I see that I need to be more specific… replace uCode with “AGESA Code”. AGESA is an acronym for “AMD Generic Encapsulated System Architecture”, and it is essentially the foundational code on which BIOS files for AM4 motherboards are built. AMD gives this to each motherboard maker and it is the base for each UEFI that the board partners then release. Intel does something similar.

          In late May AMD released AGESA 1.0.0.6 that enables memory clocks up to DDR4-4000 now.

        • Zurran

          that is not UEFI code , that is a reference code controller that’s sent to the board manufacturers to adjust cpu configuration within the UEFI that the manufacturers design

        • Zurran

          that doesn’t make what I said less true. if you used a Asus board(for example) pre AGESA update. it would still have z170 items in the base code. Because Asus and gigabite used modified z170 code for the basis of the Uefi on those boards. Then Asus used Agesa and there own PROPRIETARY software in the UEFI code on the board. Because AMD doesn’t design motherboards or the code that goes into controlling them.

  • dasa

    (We expected the performance increase to be pretty linear and have no answer for why the DDR4 2666MHz score wasn’t a touch higher)
    Apparently sub timings get relaxed when you use a divider over 2400 so if you test again increasing the ram speed via the bus instead you should see better scaling

    • Nathan Kirsch

      The MSI X370 Xpower Gaming Titanium motherboard doesn’t yet support bus overclocking as mentioned in the article numerous times. It just got the ability to disable SMT the day before the article was posted. MSI has been slow at adding all the Ryzen 7 features to their top-end board.

  • ste8875

    When I looked up the G.Skill Ripjaws it says its for Z170 chipset, would it matter if it goes in AM4? I thought RAM could go into any chipset.

    • avi raj rk

      yes ram goes both ways but for best performance and efficiency see the best ram and motherboard combo some ram run better with msi or asus or gigabyte or asrok so search it up go for the best combo.

  • Phil Brinkle

    I’d rather use Thaiphoon Burner software to read and display SPD-based information on memory modules. CPU-Z is useless since it is incomplete in displaying SPD info.

  • La caja de Raja

    R7 1700 or i7 7700K for future-proof gaming?

    • haddad

      For future-proofing anything, 1700 for sure!
      330 USD with a decent fan!

      • La caja de Raja

        but if game-wise its losing now, wont it be worse on next years like 50 fps 7700K and idk 40 fps 1700?

        • DeusEx

          In order to future proof a pc you need to bet on what you think will be more important in the future: core count vs raw clock speed.

          I am betting its the core count, because that is what happened last generation. This man explains it best;

          https://www.youtube.com/watch?v=ylvdSnEbL50

        • khanmein

          this fella is bias.. nonsense rubbish!

        • Tyrann

          Yes to future proof you have to gamble on what you think will be more important in the future. I also think more cores will do better as we evolve from just playing games to also streaming/content editing.

        • haddad

          Would like to add, I think you if you aren’t in rush, wait for the 6core or 4 core ryzen that to come soon. Pretty sure will be better buy for pure gamers.

        • Billy Pistocco

          No, the video AdoredTV made proves that as time goes on, that 7700K will lose FPS with age.. It’s practically maxing out CPU usage as it is, any further and you will start to see no benefit in a more powerful GPU.

        • SteelCrysis

          Seriously? That ridiculous claim just proves that AdoredTV is an AMD shill. It also sounds like the FLAC elitist mentioned here: https://www.neowin.net/forum/topic/1045403-do-mp3s-degrade-in-quality-over-time/

        • haddad

          Again SteelCrysis using “Shill” nothing new, not even an argument. Posting irrelevant links as usual.
          Actually AdoredTV showed great point of i5/i3 peformance degrading over the span of 3-5 years. Also from the Database of respectable reviewers. But no, he must be a shill! Lol. you funny man.

        • SteelCrysis

          Again haddad posting links from AMD shills which resurrect old issues with Hyper-threading which were addressed years ago. BTW, by your insane logic i5s shouldn’t degrade since they don’t have Hyper-threading, yet you are saying “i5/i3 peformance degrading over the span of 3-5 years.” XD

        • DeusEx

          @steelcrysis:disqus

          Dismissing the comparison that AdoredTV did based on ad hominem (insults) because you dont like what it says is not a valid arguing strategy.

          You lost the argument the moment you started name calling because there isn’t a drop of substance in your entire comment.

          As time goes on, developers utilize more cores. Why is that so hard to believe?

          BF1 comparison which shows all 7700K cores at near full load should give you a hint that if future proofing is what you have in mind, then RYZEN is the better bet.

          Hey its just my opinion.

        • SteelCrysis

          @DeusEx

          “AMD shill” is not an insult, it is a statement of fact based on his behavior.

          You lost the argument the moment you started spewing non sequiturs about ad hominem. Spewing non sequiturs because you don’t like what I’m saying is not a valid arguing strategy.

          A video by an AMD shill does not prove that Ryzen is the better bet.

          Hey, it’s not just my opinion. It’s the facts. Also a fact is your pathetic attempt to weasel out of being called out by saying “Hey its just my opinion.” And by the way, it’s “it’s” not “its”. Someone must not have graduated college.

        • Billy Pistocco

          I’m only going by reviews conducted by third party websites. The only thing AdoredTV showed me was other users benchmarks.

          2500k lost It’s performance lead to an 8350 as time went on, each GPU progressively more powerful. The logic being “low resolution testing indicates future performance as graphics cards become more powerful.”

          2500k beat the 8350 using a gtx 680 at the time of testing, fast forward to 2017 and the same tests. Same games using a Titan X, show the 2500k losing to the 8350 by around 10% across the board. The complete opposite of what was supposed to happen.

          I’m on an intel CPU right now but that’ll change in a week or so. I’m not biased, but the lack of innovation and the thousand dollar processors is what happens when there’s no competition for half a decade.

          I can do two things. Buy an overclocked Skylake chip for $350. That’s all kaby lake is might I add.

          While the arguments against AdoredTV made in this thread are weak, it does turn out that he was extremely off base in that video.

        • Oscar

          Sift through some benchmarks, in 1080p the 1080ti is choked by 7700k.
          In wery few games framrate minimum is the same as the maximum.

        • SteelCrysis

          What does that have to do with Ryzen? BTW, ExtremeTech begs to differ with you, the 1800X chokes the 1080 Ti at 1080p even before the 6900K: https://www.extremetech.com/gaming/245604-review-gtx-1080-ti-first-real-4k-gpu-drives-better-amd-intel

        • Any CPU bottlenecks at 1080p in almost any game with any good graphics card, 1080p is the baseline standard nowadays, anyone running a 1080ti isnt so likely to be running a 1080p monitor, more likely a 1440p or 4K monitor, which actually makes use of the gpu power available nowadays.

        • SteelCrysis

          That’s not the point of the ET article. The ET article proves that the 1800X becomes a bottleneck before even the 6900K.

      • SteelCrysis

        1700 is not the best for futureproofing gaming. As GamersNexus explains: http://www.gamersnexus.net/hwreviews/2822-amd-ryzen-r7-1800x-review-premiere-blender-fps-benchmarks/page-8

        “AMD defends its position by indicating the ISVs need to begin supporting their product, and has provided us statements from StarDock and Bethesda relating to this. To these statements, we’d remind folks that games take a long time to develop. Buying a CPU now in the hopes that games will better leverage 16T CPUs in a few years is a risky move – particularly with Bethesda’s track record for game optimization.”

        • haddad

          You selected the worse reviewer out there! LOL.
          Even Jaytwo cents made better judgment on Ryzen compared to GN.
          Ryzen gives way smoother gameplay as compared to 7700K. In many cases 7700K is reaching 100% cpu usage causing alot of noticeable stuttering. That has been noticed/ mentioned by many reviewers and Consumers who bought ryzen.
          Read this reddit:
          https://www.reddit.com/r/Amd/comments/5xpnla/game_stuttering_is_basically_nonexistent_since/

          Why anyone would pay extra 20$? for worse cpu the 7700K with less threads and without a fan? 1700 is the way to go on budget now and future proofing. Also wait for the optimization from windows to occur!

        • SteelCrysis

          “You selected the worse reviewer out there! LOL.”
          Why? Because you’re an AMD shill and you don’t like the truth?

          “Even Jaytwo cents made better judgment on Ryzen compared to GN.”
          Actually, he said this: https://www.youtube.com/watch?v=SE4sxXva9Eg
          “In fact, there’s even online evidence of AMD getting their nose extremely out of joint with reviewers who decided to do 1080p testing. AMD believes that these CPUs are directly aimed at 1440p and 4K gamers. Now I’m going to go ahead and call that out as a load of crap, because the more resolution you put into your game, the more you’re offloading the load onto the GPUs, and the CPU becomes less of a factor. 1080p gaming is a very relevant test to CPU overhead, because your CPU is tasked with trying to keep up with the massive amount of frames being drawn by your graphics cards. In fact, if you go look at the Steam hardware analytics, you will find that 1080p gaming is still extremely dominant. So that’s why we do 1080p gaming, it is talking directly to the majority. But then again, it’s also very fair to call me out and say ‘Jay, most people with a 1080p panel wouldn’t be running dual TITAN X Maxwell cards,’ and with that I would say ‘you’re absolutely right,’ but this was a good way to see just how far we can push the FPS before the CPU really starts to become a factor.”

          “Read this reddit:”
          There’s no need to take seriously an obvious AMD shill recycling an issue that was resolved years ago.

          “Why anyone would pay extra 20$? for worse cpu the 7700K with less threads and without a fan? 1700 is the way to go on budget now and future proofing. Also wait for the optimization from windows to occur!”

        • Zurran

          its not a shill video its fact backed by facts. Something a shill could never understand

        • SteelCrysis

          It is a shill video, because of how it attacks Intel using the truth. It’s no different from the racist Council of Conservative Citizens’ attacks against black people, by specifically focusing on black crimes.

        • Zurran

          its not an attack , its stating facts about a immoral company with no ethics. something you share.

        • SteelCrysis

          Yes, it is an attack by a shill for an immoral company that is proven to use paid shills.

        • Zurran

          ah , i get it now. your a paid shill. i didn’t know you could do that as a career choice.

          And if you jumbled up the windows scheduler on a 7700k it fall behind ryzen by 600%. If you knew anything about computer science you might put more facts behind your baseless claims.

        • SteelCrysis

          Care to post some proof? XD

    @ Nathan Kirsch
    Thank you for a well presented article. Given all the fud around at the moment; its nice to have some clear ( unbiased ) analysis. Obviously, given the immaturity of X370 B350 and Ryzen in general; when the faster ram speeds are supported, the benefits to content creators and gamers will not only be felt, but enjoyed.

    Good work Sir !!

    • Ammaross Danan

      The benefits are already enjoyed, even without high-clocked memory support yet. My Premiere rendering times were cut in half moving from my old 3770K@4.4Ghz to a 1700X with a quick OC to 3.8Ghz. Just bumped it to 3.9Ghz for some testing. 😀

  • Liclac

    Thanks for this article. Many reviewers said that anything above 2666MHz is a gamble because of this early memory compatibility issue. So, 3200MHz should work just fine? Or should I play safe and get the 2400Mhz?
    AsRock X370 Taichi motherboard and 3200MHz TridentZ RGB 2x8GB.

    • Daniel Waddell

      It seems like Ryzen only likes to play nice with Samsung memory at the moment Gskill has Ryzen certified memory it might be worthwhile looking at that https://www.techpowerup.com/231204/g-skill-announces-flare-x-series-and-fortis-series-ddr4-memory-for-amd-ryzen

      • BraveLabrador

        They reach those memory clocks with increased CPU bus speed. For that you need a motherboard with an external clock generator.

        • Ammaross Danan

          Yep. Taichi, Fatal1ty Pro Gaming, or Aorus G7 (Not G5!) are the ones I can think of off-hand.

        • BraveLabrador

          The point is, those memory modules are just a gimmick. Any 3200MHz module would be fine.

        • Nathan Kirsch

          I’ve had no issues here on single-rank modules running 3200MHz in dual-channel mode. I’ll have to try out filling all four slots and see if I can still hit 3200MHz and update the article.

        • Nathan Kirsch

          Article has been updated with Page 5 including 4-DIMM performance now.

        • Liclac

          Thank you for the updates!! Now I’m thinking which one to get. 2400, 3000, or 3200. 3200 is the best performer here, but the availability is very limited. 2x8GB is enough for now, I hope they are taking this matter as top priority right now.

          Regards

      • Liclac

        Thanks for alll your reply.

        I found ASrock X370 Taichi QVL, and they have Trident Z RGB listed there, slightly different, F4-3200C16-16GTZR (QVL) and F4-3200C16D-16GTZR. Don’t know what that means.

        If I stick with QVL will I be safe without complicated timing and voltage tweaking? I mean, even though it’s in QVL, it’s 3200MHz stick rather than the safest 2400MHz.

        Sorry if my questions are pretty dumb.

        Thanks

  • Lightider

    Any disadvantage to running four 8gb dimms for total of 32 gb memory?

    • Nathan Kirsch

      Yes, you can only run them at 2133MHz. I’m updating the article to show this.

      • AM4guy

        So what is the best configuration to get 24GB of RAM with the highest frequency possible? What about 32GB? Thanks!

  • Thanks for this article, I wonder how the HyperX Savage DDR4 2400MHz 16GB
    2x8GB (PC4-19200) CL12 would fare compared to those CL14 timings in those tests. I know the HX424C12SB2K2/16 are supported on Gigabyte GA-AB350-Gaming 3. Cheers.

    • Nathan Kirsch

      less than 1% if that at 2400MHz to be honest in real world benchmarks. Not a significant difference between CL12 and CL14 at 2400MHz with both running 1T command rates.

  • Doug Hoenie

    What about 2x16G kits? For a total of 32G. Why were those not tested? Is there a disadvantage with those? Thanks.

    • Nathan Kirsch

      We don’t have any 32GB kits available for testing here. If we get sent one we’ll certainly take a look at it. You are looking at $229 for a 2400MHz kit and $310 for a 3200MHz kit, so it is safe to say that is not going to be widely used today. A couple years from now it will be.

    • leexgx

      2x16GB is what i am interested in as well (not an issue on intel) so can expand to 64GB if needs be (but don’t think i need) now for the review reading

    • Ammaross Danan

      I’m running 2x16GB TridentZ 3200Mhz CL16 on an ASRock Fatal1ty X370 Professional Gaming. I haven’t tested memory scaling on it yet, but BIOSes are a little weak at the moment. Still need to look up if there’s a memory timing editor, as one isn’t readily apparent (yet?) in the OC Tweaker (even in manual mode).
