It will encounter errors or crash in a few minutes of Prime at these settings but playing games, video/photo editing and encoding, video transcoding work, 3D modeling work, etc it has been absolutely stable without a crash in at least 6 months of heavy daily use now. It may be heresy around here to say but you just might be "stable enough" with a little more tinkering if that is acceptable to you. Otherwise you might need to look at better cooling or more power still to get it truely stable. Also consider sticking a fan behind the CPU socket on the back of the board if you have room and something blowing down near the front of the socket if you can. In my experience this can drop core temps a good 10-15C in some cases which may help if heat is part of your instability.
Truth, I've read that point a few times around here. Ideally, i do agree with you, but at the same time I'd like to make sure that it can really take a beating at these settings. I tend to multitask and also do some pretty tough video rendering (1080p or higher at usually 60fps or higher). Granted I'm sure it will still never hit what prime95 does, it's just good security i suppose
