Dude that is wrong. CPU Termination only goes to 1.7v on my UD3P board. There is absolutely no way you are running 4volts lol. You would be sitting next to a pile of ash if you were. Please re-check. I run CPU termination at 1.6. I would also do as bugjae suggested and change to 400 2.00D for now. Also PLL to 1.4 1.5 or 1.6 instead of auto. In my case auto was 1.8.
