Accuracy of CPU-Z voltage vs core temp's

So I was running both CPU-Z and Core Temp at the same time while doing a Prime test and they both had different voltages.
My 2500k is OCed to 4.5.

CPU-Z reads: 1.26
Core Temp reads: 1.36

Does anybody know which one is more accurate?

Well, what is your BIOS set to?
Whichever reflects that is the correct one.

Core Temp is showing you the VID, not the actual voltage. CPU-Z is showing you the real voltage.

Anyway you should not ran CPU-Z and Core Temp at the same time.

Why not?

These programs are not meant to be run in tandem. Essentially, you should only ever have one monitoring program open at a given time to ensure reliability of the readings.

I'm assuming this is because they are polling the same sensors to get their measurements, and having multiple programs do this greatly increases the chances of inaccurate readings for either program.

Try to ran each program at time, simulating the same environment, and see if they got the different readings.
