PCProbe loads fine for me.

If you will leave voltages in BIOS at auto then CF IV will adjust them for you and overvolt everything!!!!

I've set them manually and all is in line now. CPU-Z and PC-Probe voltage readings are quite accurate.
Obviously it's quite important to remember that Voltages set in BIOS as offset will increase vCore for example above CPUvid value. So setting in BIOS offset +0.1V results in 1.4V in case of my Phenom 1090T with Turbo enabled this brings total to 1.575V on poorly threaded loads. Asus TurboV will still show only 1.4V but CPU-Z and PC-Probe will reflect close to real value.

I'm on a 0707 BIOS BTW.
