Ok it keeps getting better and better with this 723A as far as voltage is concerned. I started at 1.6 just because my L722A took 1.675 for 4ghz stability. I'm now down to 1.525 (1.46v Windows Loaded) for my most recent tests. I've only been running prime for an hour, but i also ran 2 loops of 3dmark 06 while small fft was running. My max temps loaded are 53c with coretemp, 50c everest, and thats with a bunch of air still in the loop. After another hour i'll try 1.5v in bios. I'm excited about so little voltage for 4ghz. Aren't you? lol Here's a SS
