I replied in the other topic but not sure whats the current state.
Don't use the auto OC. Start with curve optimizer at BIOS level, if BIOS is too cumbersome, then use Ryzen Master.
Start with -10 stress test it a lot then go for -20 or -30
This is normally the entry level for light OC. Learn your ways then you can fiddle with per core optimizer, scalar, voltages and so on.
Good luck
