System Fatal error CPU:7 (19:21:2) MC5_STATUS...

Hi. I've been using linux for about a year, Arch for 3 months, I've never had hardware errors before. It all started a few days ago, I bought a “new” GPU - RX6700XT. I had some problems installing it, for which I had to reset the BIOS, take out all the pc components and put it back in. After that the card worked. But arch took a long time to boot the first time with the inscription “Loading virutal initial disk”. I didn't pay any attention to it, the same evening, arch didn't want to boot at all, giving fatal error “CPU:(1 to 12) MC_5_STATUS”. At the same time, Windows boots normally and works completely correctly. And also linux system can still start normally via linux fallback initramfs without giving errors or with “recovering jouranl”(Not often, about once every 10 reboots.), I even started once and thought the problem was gone and spent several hours in the system, playing and using the browser, no errors or crashes.
I tried different methods to fix this error that I found on the internet, I disabled Global C-States, PBO, started linux with amdgpu.featuremask kernel parameters, increased CPU voltage via zenstates, reinstalled the “linux” package in the booted system as well as the “mesa” video card drivers. Due to the cheapness of my motherboard, I don't have curve optimizer, which is mentioned in the guides on how to solve this problem, so curve optimizer doesn't work in ryzen master from Windows.
But I still think that the problem is either GPU related or software related.
