I've read in various places not to trust software readings of voltage on power supply rails. . .But this has me kinda worried even though I don't trust it. I was just using this program to measure temp, since it displayed right on the desktop. For anyone wondering, it's pc wizard '07. Here's the power readings:

Voltage CPU : 1.34 V
Aux. : 3.25 V
+3.3V Voltage : 2.02 V
+5V Voltage : 4.93 V
+12V Voltage : 13.46 V
FSB_VTT : 2.02 V
VBAT : 3.14 V


Should I be worried?

These are just the readings that the sensors put out. If the sensors aren't accurate, or the program interpreting the output isn't accurate - your results won't be accurate. Long ago I found out the hard way not to rely on sensors (except as a general indicator) - but rather to take the measurements myself using a tool designed for it. You can get a multi-meter pretty cheap these days and find out for yourself what the actual results are.

Yeah I've got a pretty cheap multimeter, but frankly I don't want to go through the trouble. If it's nothing to worry about, then I won't worry.

software depends upon chipset support and newer computers rarely read right, if the mobo manufacturer has a utility I would trust it more otherwise I would check bios
