Apprently someone figured out a way to unlock the 2 extra cores that are disbaled in the Athlon 64 X2 7750BE which turns it into a Quad-Core by using the Advanced Clock Calibration (ACC) feature in the BIOS. If this turns out to be the case then that means that you will be able to turn a 58 dollar Dual-Core processor into a Quad-Core processor that will be faster then the Phenom X4 9950BE. As for how stable it is with all 4 cores? That is yet to be seen. http://www.techpowerup.com/92330/At... First it was the Phenom II X3's and now this. It does kind of make you wonder if this is just a coincidence or some sort of AMD easter egg marketing scheme. ;)

I was reading some comments about this in another forum. The general understanding is that AMD takes defective Phenoms X4's & either disables one or two cores as necessary, thus creating the X3 or X2. But since they have now created a market for the X3 & X2, what happens if they get an extremely good run on X4's? They will have to take perfectly good X4's & turn them into X3's or X2's to satisfy the demand. It will be interesting to see how many people are successful at unlocking them.
