Okay, just did a couple of clean restarts. I think even with double boot, the system should restart without double booting right? I dont' remember what it was like before. It booted fine by doing restart in Windows, no double booting. It's working great now, oc'd to 3.0Ghz no problem. Will try to find the lowest vCore for running 3.3 once I get to Xmas. The board is fast, that's for sure, and stable, just the booting thing.
I think the BIOS12 is still the most stable and fastest. I think once I cut off AC power, it'll double boot, but at least now I don't have the occasional "non starts" where the thing just powers up and nothing else shows up. I sure hope they figure out a way to fix this boot, maybe a BIOS 15 over the Xmas or something. if not, I think at least now I can live with double boot on every cold start.
