X2 550 Unlocking & Overclocking Consolidated

[ASharp]

Unlock as normal in BIOS by enabling ACC. This will unlock the other two cores to make it a quad. In the case that the last core is unstable, you can use the Processor Downcore feature of your motherboard (assuming it has this option) in your BIOS. It is here where you can set it to run at just three, two, or even one core.

Thanks for the info.
