Where does it correctly display my vCore voltages?

Hi, I'm sorta new to this overclocking thing and I'm not sure where to look for the exact vcore voltage. I am on an ASUS P5N-E 650i SLI mobo, and in the BIOS voltage configurations I have configured it to 1.29v to run my e6400 at 3.0ghz. However, none of the programs like CPU-Z, PC Wizard 2008, OCCT shows it as 1.29v. In another tab of my BIOS where it shows the temperatures and voltages in real time, shows my vCore as 1.26v. Which is weird when all the other programs I mentioned above shows it as ~1.34v. Where can I find the actual voltage going into my CPU?

A multimeter. ;)
Otherwise, neither 1.26 nor 1.34 is going to burn up a core. So its fine. Temps matter more than voltage.
 
A multimeter to get the most precise reading. Otherwise, you'll notice what's known as vdroop. You can download a program to use such as CPU-Z which should give you a fairly accurate reading of your vCore.
 
You'll never get an accurate vCore reading without a multimeter. If the system is stable and not operating above 60c I say leave it alone. But if you're still concerned about it, you could try finding the lowest stable voltage by dropping it down a tick and running Orthos/Prime95/OCCT every night before you go to bed. It will take a few nights, but you're guaranteed to find what you're looking for.
 
Just make sure that you don't set anything over a 'safe' vcore voltage in your BIOS. For the E6400, I would say not to go over 1.5 volts.
