Yah, keep at it, you're bound to have failed sessions. I just poured about 20 Liters of Fail Juice on my 670 setup. PURE FAILURE!

I aint gonna let it get me down for longer than 30 minutes.

Problem found tho, I changed up my insulation job and left a gap in the logic. I didn't create an air-tight seal around the cpu socket so after being 1/4 of the way into the bench, none of my old settings worked and I spent the remainder trying to find settings that would work. Just to find out, the insulation job blew chunks.

Live/Learn :)
