Seemingly my Phenom CPU, ID 00100F42, has been re-sized  by Patch ID 00C6 from a 2-core X2 550 to a 4-core X4 B50.

No-one has been around cutting the core into smaller segmengts as far as I know. But the BIOS tells me something has happened.

How this has taken place I have no idea. Can anyone advise??

PhenomII x2, x3 cpu's are all quad core cpu's that had one or two core's disabled so what that patch did is unlock those other two cores. But, AMD locked those cores for a reason.


FX 8320// Asus Sabertooth R2.0 // HIS R9 280x //8Gb of 1866Mhz ram, H50 cooling, HX850W psu all stuffed into a NZXT Phantom case.

If the new found cores function without issues then use them. Some PUs had cores disabled because they were not equal in quality to the active cores. In some instances the locked cores were disabled for marketing reasons. The highend mobos often allow you to unlock or disable cores. If you develop system stabilty issues you could disable two cores and see if the issues disappear.


Building a reliable PC involves more than just assembling the parts. You need to be able to configure all of the BIOS settings appropriately. This can be quite involved and frustrating as it can require a lot of trial and error with stress testing. It is however often the only means to get a 100% reliable PC.
