Voltage...
I have my q9400 clocked at 3.2ghz. It's a 400mhz FSB, and the multiplier is 8. Anyhow, it's slightly unstable, and I've been pulling the voltage up. In my bios it's 1.30675, or something like that, but in CPU-Z it reports 1.28. My question is, which one do I trust?

Re: Voltage...
The BIOS setting is usually a little bit off from actual voltage. There should be somewhere in your BIOS that shows what voltage your various components are sitting at. You also have to take Vdroop into account, usually your Vcore at load should be at your CPU's VID.

I'll check in my bios, I'm sure it's somewhere in there. My board is the ASUS P5E3, it's on the X48 chipset, if it helps at all. Thank you for your help btw

Re: Voltage...
vdroop is basically a decrease in voltage, caused by the PSU or mosfets.
It varies based on the board, but sometimes will cause voltages to drop by a large amount at certain times. This site explains it much better than I possibly can. http://www.thetechrepository.com/showthread.php?t=126
