ive got 4x1gb OCZ2P10002GK running very stablily on this board. ram is at 503mhz @ 2T 4-4-4-4-14 @ 2.3v

It actually took me a while to get this stable at these speeds. I did a LOT of testing to nail it down as I really wanted to have the 4gb and needed it 24/7 prime stable for video editing. I have a hunch that two of OCZ modules are the slower GMHs keeping the whole pack down, while two of the faster ones may be GKX which hit over 580mhz @ above specs.

First, put a fan on the ram. No questions asked. I've seen too many people fry their chips running north of 2.3v. Next, get a bootable cd of memtest and run each 1gb stick individually on the left most dimm slot next to the cpu. Run test #5 each time increasing your ram mhz clock until memtest spits errors. Write down the speed at which EACH chip runs stable. Next, sort the 4 1gb modules from slowest to fastest and place them respectively left to right on the board.

I found that placing the slowest chips closest to the cpu and the fastest furthest away I was able to run a lot faster and a lot more stable. After you sort them by speed, run memtest #5 again with all four gigs in the board and find your top speed.

Good luck.
