Happened to me too after 3 days of Blend / Small / Large...following the "episode" I was as stable as a three legged table but strangely enough I left it powered off overnight and since that have run 510x8.5 without any issue (Personally I think the BIOS got fed up of my and tried revolting!).

The strange thing about my system is that I might Prime for 12+ hours, even 24, then it fails or I stop the test, and it fails almost immediatelly when I start again. I don't get it. Like last time - 24 hours passed with heavy gaming and movies meanwhile, and then "Prime95 stopped working..." after lousy one hour. I know there is SOME instability, because 450x9 didn't fail once in either way, but bloody hell, I am getting tired.
I WAS stable at 533, then 540, then nothing, and now even 510 kicks my unholy butt? Maybe it's time to buy i7.

I was going to respond to this earlier today with exactly what Psycho had posted, but I knew Psycho would want to do the honors as he is one of the resident GTL ref gurus.

Hey D-an-W was just wondering how you came along with the Mac OS? I was thinking about trying it again. Did you do yours on a separate hd or did you use a partition? I have been able to get it to install but would not boot. I think it was a bios setting. Did you have to make any changes in the bios to get it to work?

Dan if you make a MAC Guide, please PM me the link and I will add it to my signature for others. You should do the same.
I would sticky it, but I don't think we get enough MAC Users to warrant that.
Ever thought about making a P45 overclock guide? That would be superb if you felt up to it, much better way to spend your time instead of testing 72 hour prime95 run
Side note I found a copy of Snow OSX universal install distro (10.6) supposably the first Mac OS distro but I could not boot up as it was "Still waiting on root device" error.

What's up with everyone? Dan busy in the kitchen and other sorting through their butterfly collections? :P
I think I FINALLY nailed my dreaded 534x7.5 setup down - maybe, MAYBE it was too low VCORE for Blend test. Not 100% sure, but I passed 30 hours! I am gonna give it a shot at 540x7.5 again after dozen weeks. MCH core still at 1.3 though, but I am at the point where I no longer care.
What I gotta live with is that I probably have slightly inferior CPU that requires 1.36250 past 4GHz :(
