The most I can get right now is 3020MHz @ 1.75V stable. Idle temp is 38 and load temp is 45 with a Swiftech MCX 462 . My memory clock is 159 right now. It's Corsair 3200. Do you guys think I've hit the limit of my cpu or my memory? Maybe my motherboard is a fault because the vcore dips down .1v. I think that might be enough to make it unstable. I can get cpu to over 3.1GHz but it fails prime. So what's the usual limit of the 2.53Ghz? What do you guys think?
