CPU-Z Claims my 805 is running at 2.6v...

Okay, I'm running a Pentium D 805, completely stock, on a crappy ASROCK 775-TwinsHDTV (until I can afford a nice mobo and 2Gb of DDR2, anyway).

I bought it new and plan to overclock in the future once the rest of the system is up to it. Having heard good things about the B0 revision, I thought I'd get CPU-Z to tell me what I have. Turns out I do have a B0 chip - good for the future!

However, I did notice that the VCore reading was about 2.6v - this seems impossibly high to me, especially since everything is on factory settings. Given that the default VCore is about 1.3v, is it possible that CPU-Z is over-reading somehow? Wouldn't 2.6v fry an 805 if that were the actual voltage?

If it was 2.6v you wouldn't have a CPU.
The THG article on overclocking their 805 also said the voltage wasn't reported correctly, so it's not unusual that it's wrong.

If it was at 2.6volts, ur cpu would instantly die the minute u turned it on, lol the chip would let the smoke out :p

yeah, double voltage most likely would result in a smoking bubling chip, and sicne its 2x the normal voltage, id say its reporting 2x voltage cuz it has 2x cores.

I'd have to concur. That would be the only plausible answer.

2.6v would smoke your CPU. :sun:

Try looking at the options in the BIOS to see if you have a set it at 1.3v options. Try setting it at 1.35 or 1.4, and see if it is again doubled i CPU-Z. Then you have your answer. And yeah, 2.6V, you'd hear it frying/bubbling once you turned it on.

I have the same issue. CPU Z reports my cpu voltage as anywhere between 2.7 volts and 3.9 volts. I also used to think that it was simply reading it x2, however being in the upper 3.x has shown that that hypothesis is likely incorrect. CPU Z simply doesn't read the voltage correctly.
