I can't figure this one out. I put this pc together about 3-4 years ago I guess. It was a black 550be that unlocked all 4 cores/3.1. Well, this morning under Mycomputer/properties, It is now listed as an AMD Engineering sample and underclocked to 1.6, all cores still active. I was able to go into the bios and change from auto setting and clocked to 3.4 right now. I can't figure this one out so anyone with expertise, how in the hell???

EDIT: I suggest if you have AMD Overdrive installed to un-install it. Everythings working fine now.
