CROSSHAIR X670E HERO AND 7950X Blue Screening

[Tyberious]

Yikes yeah that's really expensive and I can't even find them anywhere in the uk but I guess the best thing to do at the moment is to wait.

It might take a bit as they were just released. They are one of the few 64GB kits out that will work well with AMD.

I bought two 64gb kits, so a total of 4x32GB, Corsair Dominator Platinums made for AMD, EXPO 5200. Running on a Crosshair X670E Extreme and a 7950x.

On the BIOS that shipped with my machine, 0512 I think it was, I was able to boot up at 3600 speed with all 128GB loaded but got two BSODs in the 3 or so hours before I decided to yank one of the kits and just run on 2 sticks. Perfectly stable since then.

I have now updated to BIOS 0705. Should I even bother trying to get my second kit in at this point? Any chance last couple updates fixed this? I really don't care if it only runs at 3600, I just want to have the full 128GB stable. I bought the kits knowing about the reduced speed issue but did not know that 4 sticks would also be unstable.

Hello,

Stock for 2 DIMMs per Channel is 3600MT/s, meaning at complete defaults you should be able to operate the two kits. Do not enable AMD EXPO or any overclocking (including PBO) and test stability with Karhu Ramtest or OCCT memory test.

Combining two kits of this density is unlikely to work beyond this frequency at this stage, nor is combining memory kits recommended.

Does this recommendation apply to two identical kits? i.e the same brand, sub brand, size, speed and latency?

Hello, thanks for the reply. Unfortunately, back on the shipped BIOS I did run it at 3600, EXPO was not active, and no overclocking or undervolting. There was no need to test with OCCT because it BSOD'd twice in the first 3 hours during normal light usage.

The kits are identical across all timings and settings, which I thought was supposed to be okay to mix again these days. Sigh.

[Qwinn]

Oh, and also - no overclocking or PBO, understood, but would running in Eco mode via Ryzen Master be permissible?

Happy to report that on BIOS 0705, all stability issues seem to have been resolved. I can run my two kits for a total of 128GB (4 x 32G) RAM on Auto (3600) speed with no issues, passed 6 hours of Memtest86 and 1 hour of stressapptest with flying colors. I don't really mind being limited to the 3600 speed for now, as actually being able to use the full 128GB RAM stable is far more important to me.

I just received the new G.Skill 2x32 64gb F5-6000J3238G32GX2-TZ5N Kit and when I turn on the pc I get the Q-Code C5 any idea's what that could mean?

I purchased two g.skill memory kits for a total of 64GB of ram, and they run fine with the AMD Expo II profile on bios 0705 and bios 0805: G.Skill Trident Z5 Neo RGB Series 32GB (2 x 16GB) DDR5-6000 PC5-48000 CL30 Dual Channel Desktop Memory Kit F5-6000J3038F16GX2-TZ5NR

I did have some issues with my Nvidia driver crashing with my 4090 on Windows 11, but I don't think that was memory related, as all the memory tests I ran didn't find any errors. I installed a fresh copy of Windows 10, and everything has worked without issue.

my current build should anyone be interested in if specific parts work well:
