I have this board but have found speedstep and c1e will not drop the CPU voltage when you overclock , I got an E4400 with a high multi so i could overclock and run speedstep for the best of both worlds but as soon as i go over 280fsb with my e4400 speedstep/c1e will only drop the multi and not voltage which is pointless as all energy savings come from the voltage drop. yes vcore in bios is on auto. anyone know if there is a fix or a bios that will do it??
