I am wondering how do i unlock the fourth core, nearly all the reviews I have read on amazon state it is so easy to unlock the core, I did the "press 4 to unlock 4th core" but when i did that it just booted up a blank screen so i turned my pc off and on and then it states "overclocking failed" Im not sure if its because i didnt wait or something. I am using the stock cooler, At the time i was using a very very cheap generic 650w psu and now i have the XFX 650W XXX EDITION and i have not updated the bios yet either, the mobo is an ASUS M5A78LM/USB3

Any ideas on how to unlock the 4th core?

Cheers guys, much appreciated
