I want to OC my Q6600 a little, it has a Zalman 9700 on it with AS5. I followed a guide I found to OCing on the Gigabyte 965P-DS3 and turned off most the extras as suggested. I set the FSB to 320, and my Memory Divider to 2.5, this way I get the small comfortable OC I want and my Memory runs at 800MHz still. I didn't adjust any voltages at all and the system posted fine and booted into XP. As soon as I'm done with this post I'm going to run Prime95 for awhile. I realize the normal strategy is to set a higher voltage then keep lowering it, but since a 320FSB is my goal and a relatively small OC, I thought I'd work backwards. In the BIOS, the voltage is on default which I think was 1.2375v, but CPU-Z shows as 1.184v. Here is a screenshot for now, but I'd like to hear from Q6600 owners or smart people in general who can estimate what voltage I'll end up needing to be stable.
