Best 775 board Ive ever had was the ep45c-ud3r 650fsb on stock northbrige cooler, takes ddr2 or ddr3 and loved my 2x1gb kit of hypers. This ud3lr is looking to be a good one though as well. Nice and cheap!
All stock MB voltages, put chip to 1.25vcore (no reason just though 1.1v was incredibly low lol)
