Core i7 920 rev D0 stepping 5 :)

The same is true for my EVGA X58 and my former GA-X58-UD5. If I disable three cores in bios, I get 22 with Turbo on.

I just thought they'd figured out a way to trick it into 22x multithreaded which is why I asked but I see that's not the case.

but why you need multi threaded 22x?22x is only good for single thread ,the others 3 cores will work at 20x and you need lots of vcore just to get the 22x core stable with high bclock
