I’ve been diligently attempting to help with the main thread on this bug (for a year!) and suddenly this forum isn’t allowing me to post again in it, saying new users are limited to 3 replies (I have 9). Unbelievable.
Anyway, I just want to mention that I’ve upgraded my asus x570 motherboard to the latest bios firmware, turned off the hack we all discovered of locking the graphics card frequency up high, and thus far my system has been rock solid for a week without this hack. That’s been very nice, for example, to see my temperatures in a normal idle range for the first time in a year.
hopefully this trend continues, and I’d love to hear if other people have tried the same.
