Jason G:
OK,
looks like some optimised code can push things harder than previously thought for durations too short to detect with monitoring tools. That would explain a lot coupled with overoptimistic factory or user OC's, insufficient cooling or PSU. For now I'd advise backing off any OC if you see invalids not directly attributable to being stiffed by legacy wingmen apps. In the long run I may need to detect signs of instability, and devise a more purpose built stability check.
Stable for 6 mins OCCT on max complexity is good. An hour run would be more thorough, but probably get pretty warm.

Hope I did those links right. After a half hour on the first run it only got up to 85c so temp doesn't seem to be a problem.

Jason G:
Eeh gads. If that's started recently then somethings come unstuck. Please reboot & report temperatures. I can see your driver is 280.19. If something let go, I'd like to find out what.
