I don't know why after use 10.3/10.2 tends to have temperature control thread hangs or Watchdog: GPU hangs in OpenCL after 30-60 mins and sometimes system restart, I never able to run for 2 hours.
Now I back to 10.0 everything stable and able to run without issue. My system is rx570 x6 per rig, no memory error and HW error, PSU load within limit.
I still don't know why... Is there some new engine or optimization on 10.2-10.3?
ps. I think future is here as Adrenaline Driver but 10.0 not fully support it and I have a lot of issue with 10.3
