AMD used to software-disable the 4th core on the Phenoms, but then they switched to disabling them by hardware, so that rendered any software means useless. AMD only disabled the cores to save on manufacturing - most of the time, these cores were not working properly. But as the process got better, people got 4 or more cores for the price of 2-3 :-D
