I'm only able to adjust all cores at once.
My main goal is to raise the clock of all cores except one as that one is much less stable for OC than all the others.
I also tried it with ASUS TurboV Evo; but everything's grayed out there, too.
Maybe it's got something to do with my BIOS settings? I'm using a Sabertooth 990FX Rev.1.
Thanks in advance!
