Nah, I wonīt tell anything you didnīt .. just increase vCore. 1.25V is nice for 4,2GHz OC, but probably wonīt work on BR.. theres slight difference between ASUS and BloodRage, when it comes to reporting voltages. Especially if you left lots of controls on ASUS on "auto".. Plus update your BIOS to G25 or P09 (probably G25, its I guess best OC BIOS for D0). Btw. can you monitor your voltage somewhere? Like HWmonitor for example.. to know, how much volts are in CPU at max load.. cause I kinda doubt, it will be just 1.25V.
