    Hi Link,
    in order to unlock the disabled cores you need a motherboard with the 750 southbridge.the 750 SB gives you ACC ( Advanced clock calibration) to activate the disabled cores. don't get your hopes up too high though, most of the time the cores have been disabled for a reason, either they will not unlock at all, or they are damaged and will lead to system instability, or lower the overclock potential. I own three of these AMD cpu's and that has been the case with all of them. you could get lucky and get a 'good one' in that they took a healthy quad and simply relabeled because of demand for that price point, but it would be wise to assumes that when you purchase a X2 550, that is what you will get, anything else is a bonus.
