Okay, last night I played around and got 3.6ghz stable, then I said, what the hay we'll go for 3.75. So, I got it booted to windows, but never could get more than a few minutes orthos stable. So, I just gave up, reset everything to the old standby 3.375 ghz and rebooted. I left this running and played a game before hitting the hay. Well, this morning I come in and do some stuff and reboot. Gets to the Windows with the moving bar, and restarts. After playing around, I cannot get it to boot to windows now at 3.375. I can have my memory adjusted way down and it still won't even at higher voltages than what I had been running. Anyone got any clue as to why it would all the sudden refuse to boot to settings that are as stable as what I was seeing (24 hours orthos)?
