G.SKILL TridentZ Extreme DDR4 Memory Review

DDR4 memory prices have fallen significantly over the past year and prices are expected to decline even further in 2016. This is due to weak demand for DDR4 in the PC market that is causing an oversupply and to top it off the memory makers are shifting from DDR3 to DDR4 production causing an even larger supply glut. The rather large stockpile of DDR4 memory ICs has caused 4Gb DDR4 DRAM chips to drop in price by nearly 40% between June 2015 and October 2015 alone and over 50% this year. The excess supply of DDR4 memory has significantly driven memory kit pricing down and that is great news for anyone for anyone looking to build a new PC on the Intel X99 or Intel Z170 platforms. G.SKILL TridentZ Series 8GB (2 x 4GB) 288-Pin DDR4 SDRAM DDR4 3000 (PC4 24000) Intel Z170 Platform / Intel X99 Platform Desktop Memory Model F4-3000C15D-8GTZB (1) compare G.SKILL TridentZ Series 8GB DDR4 Memory KitG.Skill has one of the largest and most respected DDR4 memory kit lineups on the market and they are always trying to develop and release faster memory kits for enthusiasts. The G.Skill Trident Z series of memory was designed specifically to offer extreme performance applications and feature the best Samsung DDR4 ICs that G.Skill could purchase. G.Skill than sorted/binned all the Samsung IC’s that they purchased and came up with 11 different speed grades ranging from 2800 MHz to 4266 MHz with regards to 8GB (2 x 4GB) dual-channel DDR4 memory kits that we are going to be focusing on today. The Trident Z 8GB (2x4GB) DDR4 dual-channel memory kits currently start out in price at $65 and go all the way up to $400. The kits all feature the same PCB, Samsung DDR4 IC’s, heat spreaders and lifetime warranty. The only real difference between the kits is how they have been sorted and had the SPD programmed for operation.

With that many speed grades available it basically forces the enthusiast to purchase a memory kit by the price of the kit as most of the sorting fun was done at the factory. If you can only afford a $100 memory kit then you are looking at a 3600MHz kit, but if you don’t have any budget you can purchase a 4266MHz kit if you really wanted to. We were sent the G.Skill Trident Z 4000MHz 8GB (2x4GB) memory kit to review that is sold under part number F4-4000C19D-8GTZ for $209.99 shipped. This kit, like all the other Trident Z kits, come with the latest Intel XMP 2.0 overclocking profiles and the new aggressive looking bi-colored heat spreaders with red accents.

The F4-4000C19D-8GTZ memory kit operates at 4000 MHz (PC4-32000) with 19-21-21-41 timings and 1.35 Volts. The tRFC isn’t really advertised, but it is set to run at 525 clocks in the SPD programming. These memory modules are fairly tall at 44mm in height, so be sure that they won’t interfere with your CPU cooler.

    Do you have any proof that x99 motherboards can use 4000MHz ram 24/7? This would make my day. My conversations with g skill so far say no.

    • Lex –

      They can physically use the RAM, sure, not necessarily clock that high though. Anything above 2400 MHz on Intel was designed for the Z170, Z270 and now Z290 and Z299 on the way, utilizing the Intel i9.

      Intel Xeon’s memory shouldn’t be pushed beyond 2400 MHz, you’ll see some really weird shit happen, if you do. Although the i7 Extremes may be able to handle it depending on the revision of the Intel X99 you have and who made your motherboard.

      I know I can clock my late model Z170 Asus and ASRocks up to CAS 18 @ 4000 MHz for a 16 or 32 GiB kit, it’s quite stable too. I’m still waiting for some engineering boards to land on my doorstep to test the X299 with an i9 to see how they fare with the same said memory modules and timing.

      On another note;

      What CPUs are you using on the X99 series motherboards are you using? The max I’ve been able to push those boards is CAS 15 @ 3600 MHz with the i7 Extreme CPUs, 32 GiB RAM installed or CAS 17 @ 3600 with 64 GiB RAM installed with the i7 Extreme CPUs.

      The best board for the overclocking is this one;


      Unfortunately, it’s one expensive board! Although, if you do rendering and deep learning like I do, other than just gaming, this is the perfect board for it.

  • Riza Guntur Prakoso

    I never have my system stable for 4ghz RAM. The temperature soaring so high thus make system crashes randomly

    • Lex –

      Are you sure you’re using the correct setting in UEFI and using the correct voltage for said RAMs? They’re really picky running at that speed. Some chip sets from Intel can’t handle going at that speed. Talk with your manufacturer of your board and ask them about the 4 GHz clock and ask them for a stable CAS timing, sometimes the lock up is caused by that, too.

    Happy with my new 16gb DDR4 3200 kit. Never had issues with Gskill and just upgraded from Gskill DDR3 1600 Ive had for 4 years now.

  • Ágoston Kubicsek

    i have 2×8 Gb 3200 mhz ddr4 but overclock 3600 mhz 😀

  • Saverio

    i would love to see igpu scalability

  • Darksword

    The actual real world performance difference from lower latency 3200 was almost nothing. Certainly not worth the price increase. I don’t know why people buy these.


      Yeah not for some 8gb kits that is for sure!! I remember buying my dual 32gb kits of 2400mhz DDR3 that I am still running today….. Shoot those were over $350usd each, but at least they were 32gb apiece and not some meazily 8gb kits for $400!

      I’ll stick with my 65gb’s @ 48-50gb/s quad channel DDR3 and hold out for some pascal with some (hopefully) NV-Link capable hardware in the near future.

    • Arnoud van Lieshout

      seriously people like you lack the intelligence, if you got top of the line specs with 144hz u need the fastest ram

  • Bassblaster505

    God damn 4.2gHz RAM

    • Nathan Kirsch

      Crazy right? DDR4 is scaling amazingly well! We just need the motherboards and CPUs to catch up in terms of being able to utilize all that bandwidth and of course run it with full stability.

    • Lex –

      Sure, 4.2 GHz RAM exists, the CAS timing is alright but the capacity just isn’t there. If your games needs a lot more memory than what’s present in the system, you’ll be going nowhere, fast.
