I bought a refurbished V8X-MX SE board, and it sets VCORE to 1.72v while it
should be 1.65v. I flashed the BIOS to the newest release (1004) and cleared
CMOS memory but it did not help. Changing jumper settings to use different
fsb speeds (100, 133, and 166) did not make any difference either.
Is there a way to make it use the correct VCORE voltage? Thanks in advance.
Your voltage appears to be normal. Here is another example.

If there is no BIOS setting, then you cannot change it that way.
There are probably web sites that show how to modify some signals
around the processor socket, but if your board is working properly,
I would leave it the way it is.
Be aware that the Vcore circuit is rated according to a load line.
That is, the voltage will vary with the amount of computing load.
Rather than a simple, single point voltage, you will find the
voltage varies due to "droop" or ohmic loss. So, sometimes the
voltage is lifted a bit, to make sure there is enough when the
processor is under full load. You might investigate this, using
Asus Probe or Motherboard Monitor (MBM5), and see how the voltage
changes when running Prime95 or just sitting idle in the Windows
desktop.
The processor has an absolute maximum of 0.5V more that the nominal
value, so your processor is currently in no danger. The extra 0.07V
will make it dissipate 9% more power than at the nominal setting.
