Just looked up what one of the votlage options actually does after I was playing with it last night
CPUVDDA supplies voltage to the VRMs. (paging DrMOS, DrMOS please come to the nurse's station...)
In the typical leap before you look fashion I was playing with this last night and it seemed to really help stability out, to the point of benching with much much less volts. I have seen people saying on the web that it "increases the voltage you set in BIOS to Vcore", I did not DMM it to find out if this was true.. but going by software readings, quite the opposite was happening (1.5vcore set 1.35 showed in windows)
What I was doing was have CPUVDDA = Vcore+Vcpu-nb
I ended up really being able to drop Vcpu-nb to levels I see the pros running (IE 1.35 or less for 2700+ NB speed) despite running 1600+ 8-8-8 4GB ram.
