Asus A7v8x-x with major vcore problems

Was Running:
Asus A7v8x-x, AMD Athlon Thunderbird 1.4ghz, 512MB PC3200 DDR RAM,
BIOS Revision 1006

Now Running:
Asus A7v8x-x, AMD Atlon XP 2100+, 512MB PC3200 DDR RAM, BIOS revision
1006.

My problem is that before the upgrade my pc would auto detect my
processor and allow me to change the Vcore settings through the 1.5v
to 1.85v (Overvolt jumper on M/B set to disabled).

Now that i have changed the CPU to an XP2100+ and the Vcore range has
changed to 1.5v to 1.7v and changing the overvolt jumper on the
motherboard does nothing.

This chip has proven to be very overclockable on a friends computer,
and I was looking to do the same on this one, but i need the Vcore to
be working properly to do this.


Any suggestions as to what could be causing these problems?
over_volt disabled = max vcore 1,7
over_volt enbled = max vcore 1,7

With the chips default Voltage of 1.55v Perhaps this 'feature' is to
protect the chip or voltage regulator from supplying too much current.
How fast do you need to get the chip? Ive taken xp2000 to 2100 Mhz at 1.6v
with no probs.
Ive also read that the Voltage is under reported on these boards, if you
measure the real voltage supplied, it can be significantly higher.

What the heck, cant you live with 1.7 :D

The drop in range is probably because the t'bred has a lower voltage
requirement than the t'bird

on my a7v333 - the overvolt jumper does not offer more options in the bios -
it just adds 0.4v to the figures shown - but the hardware monitor reads the
modified voltage correctly

If it is not working you can always up the voltage on the cpu bridges or via
a pin mod such as
