When I built my sig rig, I jumped straight into OCing it as soon as I installed/updated the OS. I could get my CPU to act stable while stressing with OCCT or Intel BurnTest for hours on end at various OC's (up to around 3.8Ghz), but it would always bluescreen or crash overnight while Folding. After 4 or 5 days of this, I got fed up and set everything back to stock. I didn't leave anything on auto, and everything was set precisely to stock. I still had random crashes/bluescreens once or twice a day. Through trial and error, I finally narrowed it down to the CPU. Not only did my BE not like to be overclocked, it couldn't even run stock with the voltage it said it needed. It even crashed when C&Q kicked in! It showed a 1.375 VID, but anything less than 1.425v crashed intermittently. Once I figured out the problem, I RMA'd it. The one I got back is currently running 4.0Ghz @ 1.475v, and it has been turning in F@H work units non-stop for well over a week now without a single EUE. While I wasn't happy with the downtime and extra cost for shipping, I'm glad I RMA'd it and got back what I should have received the first time.

TL;DR version: set everything back to stock, add a tick or 2 to the CPU voltage, and see if that stabilizes it. If it does, look into RMAing it as a defective part.
