I have always used Mother Board Monitor, but they havent updated it in forever. As it sits, my voltages do not seem to be right, but I just don't know. I just finally became able to OC my computer, and I have already hit 2300MHz, but my voltages seem crappy. Right now it is monitoring and saying that my CPU voltage is 1.42Vs. Stock setting is 1.45, and I have it set at 1.55Vs. So it would be really really nice to know if it is in fact 1.42 or what. I just had it run 3D Mark 2001 SE stable at 2300MHz, if its at stock voltage, I'm impressed. Temperatures are up from 2000MHz but not a lot. So what do you use? I want to push this thing more but I want to find out if my Core Voltage is really not changing or what first.
