I can confirm that after upgrading to the 450.66 driver I have not experienced an Xid 61 error (uptime about 4-5 days now). I am still locking the GPU frequencies to (700,1680) to keep it out of the lowest power state (P8, I believe); if I need to reboot again soon I will leave the frequencies alone and see what happens.
Previously I would encounter 1-2 Xid 61 errors per day, requiring 1-2 reboots to free up the graphics system. Whatever the change in the driver, that seems to at least be preventing the error from occurring in my system.
System:
- ASRock X470 Gaming-ITX/ac with 32GB of memory (no overclock or XMP)
- Ryzen 3700X (hyperthreading enabled, no overclock)
- EVGA RTX 2060KO
- Ubuntu 18.04 and Ubuntu 20.04
Thanks @amrits, @Uli1234 for your detective work.
@amrits, if possible for you to share, I’d be very interested to hear (and others probably would be too) how this was fixed in the driver.
