Check RAM compatibility for 7800X3D.
I faced problems after the BIOS update with 6000mt/s on four RAM sticks, then switched to two and still couldn’t reach it. I reset the CMOS many times now. I’m not hitting 5800mt/s or even the recommended 5200mt/s, which seems similar to the stock 4800mt/s. My board is an Asrock X670E Steel Legend, using Corsair Dominator Platinum CL36 6000mt/s RAM. People say it’s typical for Corsair unless you’re mistaken. I also have a G.skill Trident Z Neo Royals CL28 at 6000mt/s to verify myself. Every time I try EXPO or manual settings with full 1.3V SOC, the system slows down to around 1-2fps, causing desync and audio issues. Clearing CMOS is necessary to get back to normal performance.
It appears there are two issues to address separately. Ram either functions properly or not. In uncertain cases, instability may occur (crashes). Freezes seem unrelated to the problem. To confirm, if you skip EXPO/XMP, does your desktop still experience slowdowns? I’m using two 32GB Corsair Vengeance 6000C30 modules and they’re working well so far.
It’s clear there are several concerns here. For RAM speeds, it doesn’t seem to improve beyond 4800MT/s and I’m stuck at that level. The 7800X3D multiplier doesn’t seem to make a big difference. Occasionally I experience slowdowns or freezes without warning, but clearing CMOS seems to help temporarily. No EXPO or XMP settings reduce the lag, and the cursor stays unresponsive when launching apps. Around the time the wallpaper engine starts to lag, I notice performance drops. Earlier on, after a CPU launch day build, random restarts like display loss and system resets occurred within seconds. I replaced my PSU thinking it was faulty (from a 2016 build), which resolved that issue, but now I still face occasional resets except for those moments. It’s reassuring to hear Corsair is stable in this regard, though the domplatinums look a bit outdated. Hope this wasn’t too much to read. I’m just tired of one system acting differently than expected. I’ve checked everything possible—except swapping motherboards. Draining the system twice for re-seating parts and checking CPU heat was futile; pasting the thermal paste didn’t help. I ran MemTest one by one, and all my other drives passed without issues. I understand it might be a defective or faulty test, just trying to verify. I also ran OCCT for stability, which succeeded. After installing Windows 24H2 with the latest chipset, the problems persisted, though not significantly.
