We have similar boards. Here's a thread I posted when I OC'ed mine. http://forums.guru3d.com/showthread.php?t=336087&highlight=950 Here are a few other links to core i7 950 OC threads. http://forums.guru3d.com/showthread.php?t=336875&highlight=950 Here are some pics I took of my BIOS before updating my BIOS version about a week ago. After the BIOS update I was failing IBT so I increased: QPI/VTT voltage to 1.235v IOH core to 1.18v dynamic vcore to +0.15625v DRAM to 1.62v It turned out to be the DRAM voltage that finally gave me stability but I haven't bothered reducing the other voltages as they are very low anyway. Use this guide for OC thesis: http://www.techreaction.net/2010/09/07/3-step-overclocking-guide-bloomfield-and-gulftown/3/ ps- Dynamic vcore is a Gigabyte feature that allows you to keep power saving features on (to reduce idle CPU voltage and speed) even while OCing. Good luck
