I just ordered a new CPU....

Can someone tell me if it's gonna have to be unlocked to change the
Multplier on the KX7-333??????

Thats a tbred, so it should come factory unlocked. All the ones I've gotten so far have all come unlocked. Whether or not it is unlocked on that board, I cannot answer for you though, but it should. Enjoy the new toy
