I did the vdroop mod using a pencil. Idle & load voltages are within +/- .01v of each other. But if I set say 1.4v in bios, I get 1.34v in windows. A .06v difference from bios to windows is not favorable especially if your cpu needs more than 1.45v to achieve desired overclock. The board has been pretty solid for me. Of course my abit F-i90HD is still going strong too so I may just be lucky
