Ok, thanks. But in the bios I was wondering what changes the North Bridge Voltage. Is it the MCH core or the MCH reference or is that not it?

The MCH Core is the voltage for the North Bridge. Normally, you need to increase it as you increase your FSB (or from what I read here, even when you add more sticks of RAM to your system). I've also read many posts that state it's pretty safe to raise the North Bridge up to 1.6v, but I'm at 1.2v on my system.

There are alot of varibles to contend with on these boards. It usually takes a while to find the best combination. Take some time and go through this thread.....there's a ton of information as you go through the 43 pages.
