Probably because he can't update to an older version after flashing a newer one.

Same question from me...

Anyone know what is CPU Voltage reference, CPU PLL voltage and NB voltage reference?

Anyone know how to make PC Probe II show memory voltage, nb / sb temperature? (saw many people with screens with the program showing those). Mine only shows CPU temp, Motherboard temp, cpu vcore, fan speeds and 3.3v and such.
