F8 official BIOS (not modded)
ATM I'm using DVID +.070v @ 4.6GHz, 2600K
HWmonitor says 1.07
CPU-Z (1.58.5) says 1.056-1.068
CPU-Z (1.58) says the same
TouchBIOS has decided it had better things to do than to start so I'm afraid I can't be of any help there. God damn crappy software.
I don't have ET6 installed atm but I haven't noticed any descrepencies between what ET6 reports and what CPU-Z reports in the past.
