PBO on 2600x

[MrCognoscenti]

I have a ROG x570 gaming f, with a ryzen 2600x and a h100i aio, i enabled pbo and the cpu went up to 4.25ghz with votages going up to 1.5v, is that normal, i dont feel comfortable with it. Can i lower the max voltage it can draw?

[Cyracus]

Normal, yes. Safe, probably not. Only way I found to reliably keep voltage under 1.4v was set the voltage to manual in the bios

[MrCognoscenti]

So if when i set the voltage to say, 1.4v manual, will it draw 1.4 all the time or will pbo make it go up and down?

[Cyracus]

it will deliver 1.4v constant (lower under load because of vdroop, medium LLC recommended).
Power draw shouldn't be a big concern as when not under load it draws less wattage and voltage remains the same. It won't be as power efficient at idle as stock behavior can be, but you get rid of those obscene voltages so it probably works out (especially if you don't leave your computer idling very often)

ok, thank you.
