Sometimes my entire screen will turn green requiring a reboot. This has happened while gaming but also while watching videos in browser. I’m trying out undervolting/underclocking using LACTL. Have you experienced this? What was the cause and how did you fix it?
I’ve experienced random stuff like that in past - not exactly the same though and not that chip.
I’d suspect power issue, either cpu and/or gpu causing a spike that results in some voltage rail to go unstable. More likely GPU, unless your applications are really thrashing all cpu cores.
How old PSU? how much headroom? how good brand of PSU? Might also be a motherboard power management issue.
Also - it might not hurt just to unplug and reseat every power cable.
Please excuse me dropping off the face of the Earth for a few days. Power supply is Corsair 750 W. Linux 6.14.6-109.bazzite.fc42.x86_64 AMD Ryzen 7 9700X (16) @ 5.58 GHz
