Upgraded to amd 5900xt & 7090xt and am experiencing random crashes. No overclock, no xmp/docp, no pbo (not defaults cause Asus has pbo on by default). 1000w seasonic PSU.

Whole screen goes green and reboots. Happens in heavy gaming, watching YouTube and even at idle.

Journalctl lists an mc5 hardware error suggests the cpu, but none of the troubleshooting has fixed it.

BIOS updated, c-states disabled, triple checked all settings, fully up to date Arch, but still randomly crashes.

Where do I go from here?

    This is what comes to mind for things to check:

    • Check your cables. Make sure none of them are loose, damaged, or obstructing fans
    • Make sure your RAM is seated properly, your GPU isn’t sagging, the heatsink is properly attached to your CPU, etc.
    • Watch the thermals and physically check to make sure that your fans are actually spinning when they should be
    • Disconnect the GPU and see if it still fails
    • Run a memtest
    • Try a different kernel (newer is usually but not always better…)

    Good luck. Hope you can get the gremlins worked out soon!
