VCORE Problem on A7v333

[Guest]

I got a replacement a7v333 board from ASUS and the vcore voltage seems
to be pegged at 2.11 volts and the boot sequence stops until I either
try to fix it in the bios or press F1 to ignore it. I cannot get the
bios to set the voltage correctly when I go into the jumper mode and
the jumpers to set the voltage at 1.75V does not seem to change
anything. The value in the bios remains at 2.11 and Probe also shows
2.11. Changed power supplies with no change in this issue. If the
voltage is really 2.11, then my understanding is that I am within days
of frying the cpu...so I have shut everything down until I get a fix
or until ASUS authorizes another RMA for a replacement.

I am out of ideas on how to fix it. If the on-board sensor is bad,
then the real voltage is likely at 1.75v but I am not inclined to try
and physically go in an check on this...since if I cannot get the bios
to recognize the actual voltage...supposing that it may not be wrong
.....then the boot process is broken because of the warning I have to
react to.

Anybody else seen this issue and find a solution...or do I need to get
the motherboard replaced again???

I seem to remember that there is a jumper near the top of the board, not
associated with jumper free jumpers, that is not documented that allows the
Vcore to be changed or limited to 1.7V

Try looking at the latest instruction manual from the Asus website as I
think the jumpers are in there. If not let me know and I will try and find
my manual to identify the correct jumper settings.

The overvolt jumper is undocumented (but labelled on my rev 2.0) and is
located next to the vid1-vid4 jumpers above the cpu. Move it over and the
voltage will be in the normal range. The overvolt jumper is used in
conjunction with the over volt protection jumper that the manual mentions.

The overvolt jumper does not set the voltage to 2.11 - it adds 0.4v to what
ever the vcore setting is - eg if at 1.65v it makes it 2.05v.

You will only fry your cpu if it is getting too hot - I use the overvolt
option to overclock my barton 2500+ to 2500mhz.

You should check all the jumpers on the
board to be sure they are where you want
them (default ?)
Even new boards have jumpers set wrong.
Also set your bios to default also then
you can tweak it later.
