Restarts once every hour on average on my only dedicated rig 
It's been pulling 650-660 watts from wall on a 750 gold PSU, so maybe that could be the culprit. I reduced power target after reading the posts above. Now pulling 610 watts, we'll see how that works out. I thought I was way within stable territory at 650..
My gaming/mining rig is very stable though, but that's only two GPU's and no risers ..
