It's true Napalm is right here, but he's also got a BEAST of a PSU as well, and that is my next upgrade as well is another better PSU..

Also, to the guy trying for 4.0 on your EP45 and are struggling, or any of you for that matter, try raising your FSB/VTT i saw one guy at 1.20 and another at 1.22 or something. Try like 1.35 fsb/vtt if you increase that with the vcore, it helps a lot on quads and you wont need as much voltage on vcore

Also, I know Jor, the VID totally matters, I know the mobo does as well, but the VID is a big part of this as well. I got offered a Q9650 with a batch number of L842.. thats a little better, but still in the 40's so I'm iffy. I want something under L835
