PBO on or off?
In theory I'm thinking even with PBO off, the CPU's should hit their rated speeds right?
This is with PBO on. I've hit 4.6 with it off but never hit it with PBO on (6 of the 8 cores have hit it now before the update two were close and the other 6 a little further off.
It's made difference for sure.
I also had some volt issues which it has fixed.
