Random resets after cpu+GPU upgrade (Arch) (lemmy.world)

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?

Yes, your combined wattage use at peak is up to 1250, so you need to downclock, or buy a powerhouse PSU.

Your error literally says devices dropped offline. How would you imagine that happens aside from power drops?

    That's definitely not the wording in the error, so I didn't realize that's what it meant. Is there anywhere you'd recommend I read up on mc5 errors?
