Thanks again renethx. It's a bit more expensive but if it is significantly better than that Arctic Freezer Pro, I might just go for it.
DaGamePimp, I tried it a year or more ago. In fact I got my Biostar TA790G XE board just because I heard it was possible to unlock the 4th core. But unfortunately when I set the ACC to Auto, the system would just go blank and I had to reset the BIOS. Could it be because I needed to up the vcore?
I saw it was fast enough for everything i threw at it, so didn't bother much but unlocking a core would be really interesting, if possible with my CPU. Anything else I can check to make sure my 4th core is really unusable?
