it dont matter just use cpuz. i found the bios voltage and cpuz never the same but as long as you compare results from the same thing reading it you cant go wrong. but voltage dont really matter anyway, as long as you cpu dont get too hot you can keep upping the voltage. and if you looking for v droop then i suggest looking at CPUZ for that.

A Multimeter.
hell voltages matter big time, there the difference between a fried cpu or chipset and one thatl last another year!!! id trsut cpuz, or use a multimeter as jimbo suggests
if your that worried about voltages there a plenty of pencil mods that you can use (at your own risk of course) to sort out the readings, google is your friend here

i'm guessing you've never heard of SNDS? about three years ago, Pentium4 northwoods were the favoured clockers from intel, and would clock really well when given a nice big sack of voltage. untill they all died after 6 months from the voltage, which caused physical deterioration of the CPU.
the exact same thing is happening to overvolted E8400's
Well my current overclock is as follows:
Clockspeed: 3500 (389 x 9)
Vcore: Bios: 1.20625
AI suite / CPUz: 1.184
Temps: Coretmep: 40 degrees
AI suite: 27 degrees
Prime 95 stable for 20 mins, thats all ive tested it so far with large ftt's
is that ok or should i maybe change the voltage a bit? would the fact that its undervolted (according to cpu z) harm it in any way over prolonged use?

You need to test with Small Ftt's. That stress your cpu. I was testing 389 x 9 using large and prime lasted over an hour. when i used small, it bsod'ed within 10 mins and temps were higher.
i'm now testing using 378 * 9. Temps around 65.
Ive been checking my cpu voltages using various programs: cpu-z everest and AI suite, they all say 1.184v, now in the bios i read 1.2625, this was what i set to get a stable overclock, now im worried about which is right as i dont want to over volt my cpu especially as the voltage they can take safely is still unknown, any ideas on whats right?
When people say that a chip can only take so many volts are they basing that on a os application or the actual bios reading?

Your board is probably vdrooping (actual voltage being given to the cpu is less than what the bios is set to). It is very common with the boards out there. OCCT test will check voltages are stable during load should be your only concern.
Otherwise be happy it is stable and undervolting.
