I have run into a little problem. I am trying to just OC my E6600 to 3.2 GHZ, i have a zalman 9500 heatsink on it, so temps shouldnt be an issue in my case as well (antec 900). The problem i have is when i try to OC it to 800x4, it boots up fine and everything reads perfect, but when i go to NVIDIA control panel it shows the bus at x1 instead of x16. When i remove the OC it goes back to x16. Does this sound like a PSU issue?
