IDK if you already did this, but I would definitely test the RAM first using memtest+. The goal is to try to narrow down what's causing instability.
Sorry, I thought I answered the question. That might have been vague. I have run memtest and my memory is great. I can run P95 for 12 hours if I get there. After a little more time, my OC is seeming less stable. It seems to be the video card and graphics related, which is why I believe I can pass p95 for hours on end. Here is a post I put up recently in the Nvidia section because I though the instability was my video card dying. That might or might not be the case.......

25% of the crashes are on window's loading screen when it says "loading desktop". It either crashes, pixelates (then crashes or sometimes recovers), or on rare occasions it boots perfectly normal. If it boots, it will crash anywhere from 10 seconds later or 24 hours later. I can do anything from kombuster to gaming and cannot cause a crash. It's totally random.
It turns out that I clocked my everything down to stock and the problem goes away. I start moving up past 3.5GHz and the video becomes unstable. I pump up the IOH to 1.26-1.28, but it doesn't stablize it. I am under the impression any more IOH is a bit much with out after market cooling on them. I thought that was the proper step. Upping the vcore doesn't help, either. To me, it seems that when my video card changes it's clock speed (up or down) that cause the crashing. I assume this is a power saving feature. Is my video card really the wall I'm hitting or is that just the way it looks to me? If I disable the Nvidia drivers or just uninstall them (converting the card to a basic VGA card), I can OC up to 4.5GHz (with a little more vcore) which is completely stable. No crashes, no BSOD, no nothing. I ran it like that for 24 hours with out a single incident. I have done a format and re-installation of everything with the same results.
Right now, I'm sitting at 3.5GHz Edited by RobbyRoyal - 5/29/11 at 6:50pm
