Is it normal for Ryzen CPU's to not drop voltages at idle when manually setting multiplier and vcore?
It doesn't downclock with manual OC. My 5600x stayed @ 4.7 1.2v but have PBO2 tweaker set up for my 5800x3d to downclock when not gaming.
to drop voltage at idle you need pss enabled and c states enabled. Also, under override voltage you need to choose amd overclocking, not override mode. this way the voltage will drop on idle.
