I'm going to have to agree that this board is having issues with the 9x multi and high fsb's. I've been working on mine off and on this last couple days and its fine running at 350 when I have 1 core loaded with folding with the NB at 1.39v. But loading it with 2 instances, or running orthos, crashes it with a hard reboot anywhere from a few minutes to a few hours later depending on if I'm using it or not. Last night I swapped my 60mm that was only partially blowing over the NB and ram and hung a 80mm over the NB only and now its staying cool. So I bumped the NB voltage up to 1.56 or whatever the exact number is and loaded it up with 2 folding instances. It was late so I called it a night and went to bed. Low and behold my pc was still alive and well this morning! Its also nice that my AS5 has cured some, I've gained about 3C since I first installed it. Or it could be that its freezing cold here in the midwest right now.
So the agenda for tonight is trying to get the cpu up to at least 3.4, which is another 28mhz on the fsb. If I can manage the 1ghz OC I'll be happy. I mean seriously, 3.4ghz with SLI would just be teh sweetness, there's no other board in this price range that can do it right now. And I didn't want to burn 250ish bucks on a freaking 680 board. If anything I can wait and pick up a new revision or a 7series chipset later this year or something if I really want to take it to its limit. For a 130 bucks, I'm not expecting perfection. Besides, I really bought this chip to run in a media center sometime in late 07 or early 08 anyway. But that requires a decent mATX board first. The big desktop will most likely get a 45nm quad at that point, who knows if this board would handle one anyway. But that's another story altogether
