Sorry Tcar I was a bit lazy and didn't go back and read through the whole thread, sorry for that. Anyhow, I saw in one of your posts you ran Prime for 4 hours without an issue, was it Prime Blend? Have you made any changes to the settings since then, other then backing down the ram to stock clocks after the problems occurred? usually when problems like that occur I set everything back to stock to see if the issue is still there. Unfortunately, when overclocking even if you pass hours of stability testing you may still run into problems with a certain program or game.
