G.SKILL Trident Z 4000MHz DDR4 Memory Kit Review

Final Thoughts & Conclusions

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 Kit

The G.Skill Trident Z 4000MHz 8GB (2x4GB) memory kit (part number F4-4000C19D-8GTZ) that we reviewed today pushed out ASUS Z170 Deluxe motherboard and Intel Core i7-6700K processor farther than we ever have with regards to memory clock speeds. This is the first time we’ve been able to run a dual-channel DDR4 memory kit at 4000MHz and it was very simple to do. We opted to manually setup the memory kit in the UEFI of the ASUS Z170 Deluxe motherboard in order to get tighter timings, but the Intel XMP 2.0 settings for this kit also worked flawlessly and allows you to run this kit at 4GHz speeds with just a couple mouse clicks.

Performance was excellent and the aggregate memory performance in SiSoftware Sandara 2015 showed that we were just shy of 40GB/s of memory bandwidth! That is gobs of bandwidth for a dual-channel memory kit!

When it comes to pricing the G.Skill Trident Z 4000MHz 8GB (2x4GB) dual-channel memory kit runs $209.99 shipped at Newegg. That price tag makes it more than double the 3466MHz kit that we compared it to in the performance charts on the low end. Is it worth paying $120 more for a 4000MHz memory kit over a 3466MHz memory kit? More than likely not, but telling your friends that you have a 4000MHz or 4GHz memory kit sure is easier to say than 3466MHz.

The G.Skill Trident Z DDR4 memory kits have you covered when it comes to extreme performance memory kits. With 11 different speeds to pick from you’ll easily be able to find one that is able to push your Intel Z170 platform to the bleeding edge. The 4000 MHz memory kit that we played around with wasn’t able to run any faster than that on our platform, so we could be limited by the memory controller on the Intel Skylake processor, our Intel Z170 motherboard or possibly even the memory kit. We aren’t going to fuss about not being able to overclock it beyond 4000MHz as don’t feel like the memory is limiting system performance at all!

Legit Bottom Line: The G.Skill Trident Z 4000MHz 8GB (2x4GB) memory kit looks great and was able to run at 4000MHz with tighter timings than it was rated for!

    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.

    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.

    • YOUDIEMOFO

      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.
