I assembled a PC using an AM5 platform and have been tracking issues for some time. Once a month of troubleshooting followed normal operation, I installed the Dead Space remake and it crashed repeatedly—game freezes, video driver failures, DirectX problems... The list was endless. I experimented with different fixes but nothing resolved the problem. Then I turned off EXPO and everything ran smoothly afterward. The main question remains: what caused it? And moving forward, how should I proceed? My goal is to maximize my RAM usage. Who is responsible—Ram (Corsair), motherboard (ASUS), or CPU (AMD)?

System: Asus ProArt X670E. AMD 7950X, Corsair 32*2 RRX 3090, Windows 10.

The precise model number of the RAM isn't specified. It might be an XMP kit rather than an EXPO kit, so manual entry of timing, frequency, and voltage usually resolves compatibility issues.

The box mentioned AMD Expo, but I'm uncertain if that matches my model. I think it might be an AMD kit, though I'm not sure if it's compatible with my setup. The particular kit isn't officially supported, even though 16*2 is noted.

I’d still type in the timing, frequency, and voltage manually. It’s proven useful on Intel systems where XMP profiles sometimes resist enabling. Afterward, running a memory stress test would be a good next step.

Thank you for your input! I configured the RAM at its recommended speed (5,600 MT/s) and left other settings automatic, letting BIOS handle latency during initial boot. So far, Dead Space Remake has been stable after about 90 minutes, with only a few crashes. Regarding your question, it seems the BIOS-latency values met or exceeded the specifications, which might explain the issues you encountered.

It turned out to be Memory Context Restore (MCR) – a BIOS feature enabling faster cold boot. Here’s what each setup looks like:

1. EXPO + MCR: Reliable on first boot, unstable after that (when MCR activates).
2. No EXPO + MCR: Stable on initial and later boots, but memory write speed and timing are at their lowest (e.g., 4,800 44-44-44-86 instead of higher values).
3. Manual MT/s and timing with MCR: Works well on first boot, often causes issues the next time (BSOD). Leaving timings on AUTO defaults to 44-44-44-86.
4. EXPO + no MCR: Stable on both boots, but each boot takes about 1 minute 20 seconds. I chose 4 because it’s the most consistent, even if it’s frustrating.
I reported the MCR problem to ASUS; I’m hoping this helps someone.

I faced the same issue and decided to return ram and motherboard... Anyway, I've seen dozens of post regarding this issue with AM5 and DDR5, I get that the platform is pretty young but I'm surprised that there has not been someone to talk about it in the youtube community. This is a pretty big stability issue and with the high prices in AM5 motherboards and DDR5 this hard to swallow as it concern every motherboard and ram manufacturer.
