Re: bios update
Apparently people experience it to differing degrees when overclocking but no one I've talked to has seen figures like yours.
Are you overclocked?
Also to clear the cmos you need to use the jumper, if you look in the manual, section 2 page 3 there is a picture of the board, at the bottom right hand corner between the cmos battery and the 4MB bios chip is the CLRTC jumper, instructions on which pins to short will be in the manual.
I wouldn't bother resetting the cmos at this stage, just back off any overclock and see if the voltage returns a more normal reading under load.
I believe it is just an error in cpuz like I get with my pc and Intel Burn Test, IBT reads my cpu as 5.0GHz when it is running at 500MHz FSB x 8 multi because it doesn't have the funtionality to read the lowered multiplier in conjunction with the FSB so it assumes the multi is the default 10 ergo 5.0GHz (500MHz FSB x 10 Multi = 5.0GHz.)
