G.SKILL Releases Extreme Low Latency DDR5-6400 CL32 Memory Kit

G.SKILL International Enterprise Co., Ltd., the world's leading manufacturer of extreme performance memory and gaming peripherals, is delighted to announce the launch of an extremely low-latency, high-speed DDR5-6400 CL32 32 GB (2x16 GB) memory kit under the Trident Z5 family memory series, designed for the latest 12th Gen Intel Core desktop processors and Intel Z690 chipset motherboards.

Dedicated to developing ever-faster memory modules, G.SKILL is launching an ultra-low latency DDR5-6400 CL32-39-39-102 memory kit at 1.40 V with 32 GB (2x16 GB) kit capacity. Equipped with exceptionally tight timings, this extreme memory specification represents the next step of the Trident Z5 family flagship performance. The screenshot below shows this memory kit validated on the Intel Core i7-12700K processor and ASUS ROG Maximus Z690 Hero motherboard. The DDR5-6400 CL32 32 GB (2x16 GB) memory kits under the Trident Z5 and Trident Z5 RGB series is available now via G.SKILL worldwide distribution partners.

Ooooh, look at that! So all those callous CL40 modules currently on the market are just scams to sell overpriced crappy memory??
Thank you G-Skill for confirming what everyone elase already knew.
Finally some decent modules. Hopefully they will bring prices down. 600$ for a 32GB kit is beyond ridiculous.

Any chance for some DDR5-7200@CL36 or, why not, my favorite, DDR5-8000@CL40 ??

what IC is used?
is it Samsung again ?

EXTREME!

(basically just matching pedestrian DDR4-3200 C16 for latency. 2017 called, and it wants its latency back!)

6400MHz with either CL32 or CL39 timings. Interesting.

Sooo... Will it be actually faster in gaming than DDR4?

1.40 volts, that's not for the faint of heart (and neither for those who just want their RAM and CPU to survive for long).

And what did You expect? DDR5 is new on the market, so it's obvious, that it sucks, for now at least. DDR4 also wasn't on the "3600 CL16" level in the beginning. Give it a year or two and it'll get much better.

Yet, I lightly chuckled while reading "extreme low latency (...) CL32" - still remember my old DDR based on Wimbond BH6 that went as low as 299MHz 1,5-2-2-0. :)

DDR5 6000 CL 36 is already faster overall in the TPU gaming test suite. www.techpowerup.com/review/ddr5-memory-performance-scaling/3.html

DDR5 loses in some games that are latency dependent, and in those games, these sticks will probably still be slower than DDR4 3600 CL16 sticks. DDR5 6400 CL 32 is around ~10ns latency. DDR4 3600 CL16 ~8.88ns latency, for reference.

Right now the main downside of DDR5 is its cost.

Depends on the DDR4 :D
Not many games are bandwidth-sensitive, most of them are latency-sensitive.

So from a latency perspective it'll match DDR4 3200 CL16

Realistically, the answer is "it's gonna be within margin of error. Here's CS:GO at 1080p where it just doesn't matter no matter what.



And in one of the most bandwidth-sensitive games out there (FarCry5) DDR4 with tighter timings is still very very strong:



By far the biggest factor in gaming performance is Gear1 vs Gear2. There's such a huge latency penalty for running in Gear2 that you would literally need DDR5-7200 CL32 just to match a relatively common DDR4-3600 kit in terms of latency.

And the price? Ahh, I see they are too scared to announce that. It's going to be crazy money. So DDR5 still continues to be a dumpster fire.

Wth, pumping 1.4V into chips designed for 1.1? That's going to be interesting to watch.

Same process as DDR4 so they're designed for 1.5v, just rated lower.

Only 1 person mentioned the most important part of the news. And it is about pumping the voltage to 1.4V. Not good enough. Not cheap enough and most importantly improving performance whilst increasing power is not something to brag about.

So many people in this thread crying about DDR5, do you not understand how new technology works? The fact that G.SKILL is already announcing improvements this soon after DDR5 was released commercially is a very good thing.
mrthanhnguyenMy dell 4800 is running at 6400c28 1t at 1.56v.
Yikes!!! What CPU and board?

Currently $609.99 on Newegg.

Depends on the ICs. DDR4 is 1.2 v for JEDEC but SK Hynix DJR ICs can do 1.6-1.7v all day long. Samsung B-Die 1.8v if you are feeling lucky.

1.4v for Hynix DDR5 is perfectly fine with a fan. I am more worried about the SA, TX and mem control voltages.

I also have a feeling 6800+ will need Gear 4 to work. I can't get past 6600 right now on the ASUS Hero. Haven't tried Gear 4 yet...hmm maybe I should.

As you have reviewed a lot of DDR5 tech so far, do you have any information or indications that the Alder Lake memory controller actually does, or doesn't, make use of 32-bit DDR5 subchannels?

No need to announce the price, everyone already knows what all DDR5 costs:

$out of stock (excl. shipping and taxes)

Well, that was rather quick. Hopefully we can start seeing more 7000-8000+ DEDR5 at CL32.

Yes, it's absolutely a scam to get you to spend more money, has nothing to do with new technology needing time to stretch its legs and get gud. not like DDR4, 3, 2, and 1 went through this same thing.

Also, the 5g corona gives you vaccines and that man asking if you want a reciept is trying to steal your car security number through noseprint recognition.
Wirko1.40 volts, that's not for the faint of heart (and neither for those who just want their RAM and CPU to survive for long).
Are you suggesting that DDR5 designed to run at 1.4V will fail quickly because other DDR5 not designed for said voltage cant do it?
bugWth, pumping 1.4V into chips designed for 1.1? That's going to be interesting to watch.
DDR4 was built for 1.2V and there are multiple 1.6V kits out there that dont self immolate, so I think they'll be fine.
Chrispy_Depends on the DDR4 :D

It'll likely make more sense in 3-4 years, when games start using more RAM regularly. DDR4 didnt really become noticeable over DDR3 until fairly recently.

Yep. DDR4 2133 and 2400 weren't really worth much over the typical DDR3-1866 on sale at the same time and early AMD platform support for DDR4 was, ughhh. I lost track of how many AGESAs AMD put out in the first 6th months of Ryzen.

DDR4's consumer launch for Broadwell-E isn't something I remember having much trouble with, though in fairness Broadwell-E was mostly workstation builds that needed stability for rendering 24/7 so I probably used only 2133 JEDEC timings. Perhaps DDR4 not really being ready for prime-time is why Intel skipped Broadwell for their mainstream 1150 platform? It's odd that only two desktop chips came out and they were practically unattainable even at SI/OEM level.
