Since building this rig I've had major problems. First set of 3 cards were flashed with the wrong BIOS with one of the cards cooking itself at 105 degrees. Second set of 3 cards refused to cold boot but were fine if you warmed them up first. 3rd set of cards are in now and seem fine but no games will run for long. It will either freeze up with sound loop or just BSOD. 3DMark Vantage runs fine (P26577 with 3.2ghz oc) but nothing else. I've tried all sorts of different settings in the bios to try and find a stable overclock but nothing is working. I have run DPC latency checker and noticed that when I run games (eg Crysis) I get a lot of latency peaks but when running 3dmark vantage the only time I get a peak is at the start and end of a test. During a test there's no latency peaks at all. Could this be part of the problem?? High latency causing vista to report the driver has stopped?? Any help in getting this stable would be great as I've all but given up with it. I dont have much spare time and the last 3 months I've done nothing but swear at this pc! lol
I am no expert but having read thru this thread it is clear you can not expect to run this board on auto, especially with 8G of ram. Check out the thread, see what voltages are used. Your NB voltage must surely be upped to at least 1.5 with that much memory. It took me a week to get my board stable, it is surpising how much you need to up the voltages on this board. Once you do up the voltages it is possible to get this board running well. To get it running real well you need good cooling i.e. watercooling with the voltages needed.
