Yesterday's big news was that the disabled fourth core on AMD's X3 processor can be easily enabled in BIOS. The hack has been tried out by many users around the net and they managed to confirm it works, at least in some cases.

As previously noted, all you have to do is set the ACC (Advanced Clock Calibration) in BIOS to Auto and if you are one of the lucky ones, the X3 could become a X4 CPU. According to some info around the net, some of the X3's aren't stable when working with all four cores, but apparently AMD did deliberately cut some good X4's into X3's so it's a lottery.

One of our readers, Steve, has sent us an email claiming that it worked for him, and he was using Biostar's TA790GX A2+ motherboard and AMD's X3 720 BE CPU. We can wish him good luck with his new, budget quad-core CPU, and we will surely keep an eye out for additional details on this situation.
