Hi guys! New to the forum.

I have a Brisbane 4800+ and an Asus M2N-E mobo and I have a hard time overclocking. I think the problem is that the bios only let me get the RAM voltage to 1.95 So if i try 3.0,2.9 or 2.8GHZ the systems freezes or fails in orthos What is a good combination with that RAM voltage with out compromising HT speeds.
Any advise is apreciated!
