I wrote in previous posts about my problems with this board. I used settings provided by ace, no luck. However, after disconnecting most of my hardware and connecting one by one, I found (I hope) a problem. It is wd hdd. I'm not sure which one (I have 5), but most likely raptors. If I connect raptors (raid0), my 320gb sata is recognized as 500gb in bios (other 2 wd hdds are 500gb re2). As my system is on those raptors, I can't prove yet that that is the reason for instabilities and freezes. At the moment I had to disconnect one of 500gb hdds, this way I can go into windows and work. It really bothers me as on my dfi I had no problems (except low fsb - no more that 400mhz)
