Any fast dual-channel 96/128GB Kits for 7950X?

Around november last year I built a new 7950X-based system and basically had to “downgrade” from a DDR4 64GB-2933 kit to a DDR5-32GB-6000 Kit due to DDR5 still being kind of expensive.

It’s the G.Skill Trident Z5 Neo 32 GB (2 x 16 GB) DDR5-6000 CL30 Memory (F5-6000J3038F16GX2-TZ5N)

So far it has been good-ish. Very stable, fast and works as advertised, but I am kind of always out of memory and have to shuffle things around. My workloads include:

  • virtualization (WSL2, lots of Docker services)
  • Coding/Compiling
  • 3D (blender, houdini) and gamedev (unity) and Photoshop stuff, Davinci Resolve, …

As I also ran out of memory when I had the 64GB (houdini especially loves to take all it can), I wanted to upgrade to either 96, or even 128GB this time around.

The thing is: from what I read, a dual-channel config seems to be preferred over a quad-channel config. However, I don’t think there are any 2x48GB kits out there yet?

I also don’t know if trying to get a 6000Mhz kit would be any different than a 5600Mhz kit.

The only options I have been eying for a while were:

  • a 64GB kit again:
    G.Skill Trident Z5 Neo 64 GB (2 x 32 GB) DDR5-6000 CL30 Memory (F5-6000J3040G32GX2-TZ5N).

  • A 96GBkit with lower clock speed: G.Skill Flare X5 96 GB (2 x 48 GB) DDR5-5600 CL40 (F5-5600J4040D48GX2-FX5)

Would there be any downsides in terms of speed when choosing the Flare X5 kit over the trident one?

Thanks in advance!

You probably know this already, but you cannot take two 64 GB kits and run them at EXPO speed. It will probably work, but slower.

For example, I have 128 GB running at 3600. Overclocking may be possible, but I have not messed with it.

You have much better chances running the 96 GB kit at rated speed.

If you want high speed, get a 96 GB kit with hynix dies (the 6400 cl32 should be safe, but may only run at 6000 on AM5). There is a corsair kit with 192GB at 5200, which may or may not run at that speed. Kingston also has some 128 GB kits at 5200 and 5600 XMP where the same applies.

If you want to use 4 dimms, a 4 dimm kit is a safer option as rhey should be matched but it’s still not guaranteed to run at XMP.

Alright, thanks! I guess there won’t be any big difference between the 5600mhz CL 40 and 600mhz CL 30 on ARM5 then? I’d really love to keep a dual-channel setup.

192GB for memory would be overkill, I don’t think I’ll need that much.

You’re speaking of XMP kits, are there any similar EXPO kits? I wasn’t able to find any on kingston and corsair only had RGB modules…

I don‘t know of any 4 dimm dual rank expo kits. But if 96 GB suffices 2x48 is the way to go.

Gskill has some 96GB 5600 cl40 expo kits. They should work out of the box. The 6400 CL32 XMP probably need some manual tuning.
