I use a Volt meter. That is, I read how you used Everest but given that that is prone to software errors did you confirm it with a real Volt meter?
I have an Asus P5KPL-AM EPU combined with HEC 500w raptor. It's brand new, and I noticed using EVEREST, the following readings:
+3.3 V : 3.41V
+5 V : 5.73 V
+12 V : 8.94 V (sometimes 9V)
My readings on my other computer with Asus P5Kpl-am/ps and also HEC 500w shows around 12.1 V on the +12V reading.
Don't you think there's undervoltage on the 12 V rail? Is there something wrong with my power supply or motherboard? The computer is stable, though.
Or is this the effect of Asus EPU engine? Have any of you experienced the same?
