G.Skill Announces DDR5-6400 CL30 96GB (2x 48GB) Low-Latency Memory Kits

[btarunr]

G.SKILL International Enterprise Co., Ltd., the world's leading brand of performance overclock memory and PC components, is announcing the release of low latency DDR5-6400 CL30-39-39-102 memory specification in high-capacity kit configurations, up to 96 GB (2x 48 GB) kit capacity. This high performance memory kit specification will be available under the Trident Z5 RGB and Trident Z5 Royal series, with Intel XMP 3.0 memory overclock profile support.

The G.SKILL DDR5-6400 CL30 memory kit at 96 GB (2x 48 GB) combines high-capacity and low-latency to enable higher performance for memory intensive platforms and uses. The screenshot below shows this 96 GB (2x 48 GB) memory kit operating at DDR5-6400 CL30-39-39-102 with the ASUS ROG Maximus Z890 Hero motherboard and Intel Core Ultra 7 265K desktop processor.



Demonstrating DDR5-6400 CL30 96 GB (2x48GB) on AMD AM5 Platform
Under extensive research and development, G.SKILL is also demonstrating the possibility of this low-latency, high-capacity memory kit running on the new AMD Ryzen 9000 series CPU and AMD X870 chipset motherboard. The following screenshot showcases a 96 GB (2x 48 GB) memory kit operating at DDR5-6400 CL30-39-39-102 with the ASUS ROG Crosshair X870E Hero motherboard and AMD Ryzen 7 9800X3D desktop processor.

Overclock Profile Support & Availability
This new DDR5-6400 CL30 specification supports the Intel XMP 3.0 memory overclock profile under the Trident Z5 RGB and Trident Z5 Royal memory series for easy memory overclocking via the motherboard BIOS on supported platforms. In addition to the large 96 GB (2x 48 GB) kit capacity, 64 GB (2x 32 GB) and 48 GB (2x 24 GB) capacity kits are also slated for release. These memory kits will be rolling out to G.SKILL worldwide distribution partners starting in Q1 2025.

Probably 1,4v (with some hope for 1,35). My CL32 kit is much older and operates at 1,4v.
16 GB x2 kits?

I thought they had announced a CL28 version... I bought a G.SKILL DDR5 8000 CL40, but change to the ultra low latency.

Question is... DDR5 6000 CL 26 or DDR5 6400 CL30?

6400 CL30 over 6000 CL 26 because more bandwidth. You want as high as the motherboard supports actually. For example, my Z790 TUF only supports up to 7200mt/s speeds, there's no point to buying ram faster than this.

Otherwise, you're trading like 1/2 billionth of a second latency difference, if that.

That was for single rank (16GB/24GB).
This one is dual rank (32GB/48GB).

I swore I read a Techpower up article saying lower latency was better for AMD CPUs. I purchased the X870E Carbon Wifi it says 8400 mt/s was the highest. I also watched a HWUB video showing this board was capable of 8000. I think I'm going send this kit back, I just don't have a warm fuzzy over it.

Lower latency is better for all processors. But it's not just about Cas Latency.

If you have 6000 CL 30 and ran them 6400 CL 30, that would lower the latency. Your don't need to tighten Cas latency to lower it.

Also, the cpu overclock will lower memory latency.
And increasing IF frequency will lower memory latency.

I have a 14700K, so can't test theories on AMD systems, but when I want true performance and low latency, I concentrate on Cache OC. For AMD, that would be similar to IF overclocking.

But just setting XMP and go, you're not lowering latency a great deal from 8000 CL 38 to 6000 CL 30. But you will be reducing bandwidth by 1000mhz (2000mt/s).

In short, these are small differences that people take time and tweak to lower latency as much as possible. If you're willing to put in the time and effort anyways.
