It was running at around 1.425V, which is what my board is volting it to at stock for some reason. I know that's a little high for stock cooling, but I'm getting pretty good temps, so whatever. I did have to raise it to 1.45V to get it Prime95 stable, but at load it still won't go over 41C, which is still lower than my 3GHz Prescott at stock. I'm pretty happy, all in all.
