Fluctuating vCore in CPU-Z?

I'm overclocking my new MSI P6N SLI-FI, am currently at 400fsb. I'm noticing that in CPU-Z the vCore readout is fluctuating violently between 1.280v and 1.440v. Does this mean CPU-Z is lying? Or that something bad is happening?
 
To be honest I can't recall if I disabled that again after the last CMOS reset. I did turn off EIST though.
 
I was wondering about this too. I started overclocking my Opteron last night, and I noticed it jumping between two different voltages (both of which were higher than what I had set in the BIOS).
 
I had that problem with every mobo I've ever had, exect my current DFI board. CPUz stays perfect at 1.45volts. It's almost kinda freaky. My last board, even with a OCZgamexstream 700 psu, would fluctuate bad on CPUz. That board was a MSI board also, only an Nforce4 one.. As long as it's stable and not showing up higher then what your comfortable with, and as others have said, don't worry about it.
 
From what I understand, it's a setting on your motherboard. "vCore overvolt" on mine. Basically, as the CPU does more it increases the voltage a little, then backs it away. Completely normal.
