I've just gotten a 5800x3d and was wanting to Undervolt my CPU by about -20 to -30 but I cannot seem to find the core voltage option anywhere in my bios, I'm not sure if I should be using the voltage offset or not. I've put the advanced OC options on but it didn't seem to show anything extra and in the advanced menu under precision boost there is the curve optimiser but I'm unsure if that's what Im looking for either. I'm fairly new to this so any help would be appreciated.
