Hi everyone. I'm one of the victims of 7800XT deciding to crash my system.
I have a Ryzen 5700X in an ROG B550-F Gaming Wi-Fi II with G.SKILL TridentZ NEO 2x16GB 3600MHZ CL16.
Everything was fine while I was still using my old RX 580 Nitro+ but since changing it to a 7800XT Nitro+ I've started having WHEA-Logger (Event ID 18) errors.
Example:
A fatal hardware error has occurred.
Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 9
The details view of this entry contains further information.
The processor APIC ID keeps changing, so it's not related to any one core exactly. The funny thing is, it only happens once per day, with the first game that I open. After the first crash, it runs stable until the next day (might be a coincidence, but that's the behaviour I'm observing the last 5/6 days).
I've tried a myriad of things:
1) First I thought it was because of two monitors (DP+HDMI), but it happens with just one monitor (DP). Two monitors (DP+DP) is still crashing.
2) Disabled MPO.
3) High Performance power plan still crashes.
4) DDU + Just drivers (No Adrenalin). Still crashes on the first game loaded before 5 minutes have passed. Fine afterwards.
5) Undervolting, Overvolting, Overclocking, Underclocking, all combinations under the sun. Still the same type of crashes.
It's always the same WHEA-Logger error in a random core, instant reboot and then it's fine. This CPU was totally okay and stable with the other GPU. Nothing was changed.
