How accurate do you think your vcore reading is?

A lot of enthusiasts that I know use some sort of monitoring program to check on temperatures and voltages. These temperatures and voltages come directly from the hardware monitor chip built into the motherboard. The only bad part is that the more often than not, the temperature readings are inaccurate, and the voltage readins are even less accurate. If you don't believe me, hook up a voltmeter to the main ATX power connector and check the voltages for yourself.

What I am curious about is the vcore reading. Most motherboards report vcore .3-.5 volts lower than what the user sets it at. While there are those who say this is done on purpse to prolong the life of the CPU, I think that theory is pretty much just guessing. What I am wondering is if the vcore reading is subject to the same inaccuracies that we see with the 3.3v, 5v, and 12v readings, meaning that the fluctuations the are reported aren't necessarily accurate.

I think this might explain some occurrences of SNDS (sudden northwood death syndrome) where people set their vcore by the hardware monitor readings, and not by what they set it at in the BIOS.

I don't know if there is a way to actually check vcore with a voltmete or not. If there is, it would be pretty cool if someone could check this out. Any thought on the matter appreciated.

emphasis mine. actually, the mobo reads it properly, I think. theres a lot of internal resistance in the motherboard itself.
