I believe it was a driver issue. The first reinstall didn't fix it, but I tried again this morning and it took care of it. I am still getting a weird stutter issue on the desktop now. It's not OC related, because it does it with stock clocks. Who knows, maybe these drivers were rushed.
As far as my OC goes. I've got everything stable at +125 Core and +400 Mem. Like has been mentioned by most reviewers, if the system isn't taxed, this thing boosts like crazy. Playing Rocket League, it sits pretty at 2114 and 58C. In Doom, it starts at 2114, and every ten minutes or so starts to back down.
I kept tweaking to figure out where the temps would be stable long term. Even if I back it up to +75 the temps eventually sit at 76-77C for continued game sessions 1hour or so. So I dialed everything up +125, +400 and it sits at that same temp and levels out at 2038 during extended gameplay.
