Lol, probably some noob who think VID can be changed.

yep i agree!
i made it back to 0 for you
Argh I did aswell, but it's still on -1

Lol, thanks.
I liked the old forum better, without this voting thingy.

But, I thought a CPU's VID was permanent. Could this actually have changed, or maybe there was some kind of glitch and 1.15V was false to begin with? Can anyone tell me? FYI, it's right now running at 3.4 Ghz (400FSB x 8.5) stable at 1.216V (per CPU-Z, I forgot what I actually set it on BIOS and too lazy to look it up). |
The last time I ran coretemp with C1E and speedstep enabled the VID would fluctuate between 1.35V and 1.15V when it lowered the multi. This also only happened when cpu voltage was set to [Normal] in BIOS.
So...basically what iluvgillgill said.

Isn't that just coretemp giving faulty readings?

No. I don't think so. The CPU has at least two VID states.
Check the third post in this thread http://www.hardforum.com/showthread.php?t=1263928.

The other VID is no less "real" though. Your point about the stock speed/voltage is good though.
I would think VIDmax if necessary would work. Wonder if there is any correlation between VIDmin and overclocking, or perhaps undervolting?
