Does the BIOS support any overclocking/tweaking?
I’m not familliar with Rocket Lake (your CPU generation), but you may be able to bump the voltage or loosen the timings a bit to get it stable. Even without BIOS support, it’s possible you could do this from your operating system, like you can with Ryzen.






I don’t want to leap into your throat, but have you tried a clean install of a different distro on a USB? And I mean clean; no reusing your home partition, no weird configs until you test out-of-the-box settings.
One thing I’ve come to realize is that I have tons of cruft, workarounds, and configurations in my system that, to be blunt, screw up Nvidia + Wayland. And my install isn’t even that old.
Hunting them all down would take so long that I mind as well clean install CachyOS.
I haven’t bitten the bullet yet (as I just run Linux off my AMD IGP, which frees up CUDA VRAM anyway), but it’s feeling more urgent by the day.
