CPU-Z Core Voltage Accuracy

How accurate is the Core Voltage rating displayed in CPU-Z? I set the voltage at 1.375 in the bios, and the CPU-Z reading fluctuates, showing from 1.488 V to 1.520 V. Those voltages seem a bit high, and I dont want to damage my processor. Thanks.
 
For me cpu-z is 100% inaccurate, i have my cpu set to 1.350v and it shows 1.240v. Coretemp shows the correct value under VID but i dont know if that measures it or just tells you what you have set in your bios because it also doesnt show the effect of speedstep.
 
I've also noticed that the screen that is displayed just after the post screen, it shows a similarly inaccurate (according to the bios) voltage. Is this normal?
 
The voltage settings you apply in your Bios is the maximum voltage the CPU has to work with. So the voltage in CPU-Z is more or less pretty accurate, but your better off using Speedfan to check voltage or something other than CoreTemp
 
It's accurate up to a point. I think I recall reading that if you're overvolting a C2D chip it's not going to report the proper voltage (and this has been my experience when overclocking my E6400).
 
Well, I found the answer on the forum for CPU-Z:

2: CPU-Z reports a wrong CPU vcore.
A: Try to change the VCore option in cpuz.ini. This option switches between the different voltages reported by the sensor chip. If "VCore=0" (default value) reports a wrong vcore, try 1, 2 and so on.

Strangely, the latest version of CPU-Z (1.43) didnt have this VCore option in the .ini file. I happened to also have version 1.40 around though, which did. Sure enough, this trick worked.

Since the search is down, I had to find this post the hard way... going through the pages and doing a search :(
