Solved Relocking 3rd core on amd phenom ii x2 550 Tags: CPUs Core AMD Phenom Last response: August 19, 2010 5:26 AM in CPUs Share fishwife August 12, 2010 12:33:19 AM I have an AMD PHenom II x2 550 CPU. I know it might be possible to unlock a 3rd core, but it may be unstable. If it is unstable, will I be able to go backwards and relock it back down to dual core?

Just turn on ACC or UCC in the BIOS and see if it unlocks, if its unstable, just turn it off and you're back at 2 cores. | Report abuse fishwife August 12, 2010 12:42:44 AM Cool, thanks!
