Is this a normol voltage?

[ColdMiser]

I have a T-Bird 900 on an A7V and a V-Core reading 1.842 in Asus Probe. Is this a normal/acceptable voltage? I am not OCing. I am in JumperFree mode so the BIOS calls the shots.

Are there any other pieces of info that you need to determine the answer to my question?

the default voltage is 1.75volt for thunderbird i think

it doesn't hurt to supply a little more but u have to watch for the temps

The voltage always seems to be a bit higher than it's set to in bios - for me (before the volt mod) 1.85 always read as 1.94 in all monitoring utilities, including the bios. Sounds as though the board's got it set to the default 1.75, it just so happens that the 1.75V setting actually gives about 0.9V higher. If you're worried about temperature, you should be able to drop the voltage down to 1.7 or 1.65 (which ought to give about 1.74) and still run stably. Try it - it could save you a degree C or two :D

If you bought the chip second hand you may find that it has had the L7 bridges altered to overclock it and that as such they may be pencilled or penned.

Whatever the case, 1.85v never hurt anyone.

my a7v does exactly what your's and rob's seem to do. my vcore is about .9v higher than it's set to. quite nice cos it gives that bit extra to work with if you want it. so if you want to get the regular default, then set it to 1.65v and you should get around 1.74v out.

IMHO 1.85v + 0.9 v equals 2.75 v. I guess that 0.09 v would be the difference between 1.85 and 1.94. Forgive me for this.

I stand corrected :-)
I've got a couple of maths exams coming up, and here I am dropping decimal points... lol

why is the voltage not reported correctly?

I think I've heard a couple of people say that it's because the default voltage on the A7V for the 3.3V (VIO) is actually 3.54V, and as the cpu voltage is derived from this then the cpu voltage turns out correspondingly higher. You could test this by lowering the VIO to 3.3V and seeing whether it affects the cpu core voltage. It seems to work roughly though - do some maths, 1.75/3.3 is approximately 1.84/3.54, which is what we are seeing '1.75V' reported as. I know the actual process is probably a fair bit more complicated, but it's good enough an explanation for me.
:-D

After doing a little bit of reading I was not sure if that was a normal voltage for a non-OCed T-Bird. It seemed a little high, but everyone seems to agree that the V-Core my Asus Probe reports is totally within spec. Thanks for the replies.

doh!! lol.. you're absolutely right... this is what studying for semester exams will do to you... ;-)
