I probably wont be testing the new bios on LN2 until this week. My ud9 crapped out as well.. Bummer.. I really liked that board. Big bang x-power seems to work better now. I just said the hell with the IOH HEAT.. I need maximum stability and since the rampage is my favorite benching board I just decided to put an LN2 pot on the NB. All is well while benching when the IOH is at -5c
