I have this problem with Sapphire Radeon RX590.
Sometimes when I turn on/restart my PC I see - "Default Radeon WattMan settings have been restored due to unexpected system failure".
This happens with the latest drivers Adrenalin 2019 Edition 19.5.1 (Windows 10).
Also, I didn't overclock any component in my PC.
I tried clean drivers clean installation (delete driver via DDU and install again), but the problem still here.
I performed load test with MSI Kombustor but it didn't show any error or artifacts and also when I play games everything looks smooth.
How can I fix this problem?
