I should have included that info. The CPU is watercooled and at 3.15Ghz on 1.42v the temps maxed out (after about 2hrs of Prime) at 48C according to Everest. This leads me to believe that temps probably aren't the issue, YET. To be honest I should have done more testing myself before posting that question since I'll be able to narrow down the issue more that way! Not only that but since my BIOS wasn't updated during that testing it could just be a BIOS issues (the newest BIOS seems to be centered around new Quads and Kentfields in particular)....
