Hi. I've a ASrock motherboard (N68-GS3 UCC) and I've tried to unlock the other 2 cores of the AMD Phenom II x2 555 3.2Ghz. So,I have an option in bios named "ASRock UCC" and below it,"CPU Active Core Control". I've enabled both but after the windows logo appears,it just shows a blue screen very fast and I can't read anything,then it restarts. I've disabled cpu active core but still the same problem. Should I increase the voltage? There's an option Multiplier/Voltage Change and it is set to auto. But I don't want to broke anything :( If I unlock just one,windows starts normally. So, the fourth one is broken or I have to increase the voltage for it to work? I'm new to overcloking/unlocking. Any help please?
 
Solution
that means the other one could not be unlock and every time you will try you get blue screen so stay with one core unlock or go back to normal cpu core .
