hello everyone, i was wondering if someone can help me with what is probably a simple problem.

i picked up a 790XT-UD4P today with a 720BE, i put the F4G bios on, unlocked my 4th core, and things are going well.

my problem is that if i change the CPU voltage or CPU NB VID in the bios, i can't make it to windows.

if i leave the voltages to default and just boot windows, i can increase voltage with easytune.

any ideas why i can't add any vcore in my bios?
