VCore1 and VCore2 are values for cpus needing 2 core voltages input.
Some do, some don't.  Depends on the cpu type.  The Pentium MMX for
example had two voltages for the core.  The Pentium Classic did not.

Asus tends to NOT use sensor chips quite the same way others do, and do
in fact have custom chips made for them that they use in many cases
which are almost compatible with a standard chip but uses some lines

It is normal to have to use a different mapping on many Asus boards.
Often a google search will get you the right values for your model since
someone else is likely to have worked it out before.

For example there is this (A8N-E model, but likely the same chip):

Basicly says: Read the instructions in sensors.conf and swap the values
as needed and add optional devide by 2 needed on some boards.

Unfortunately Asus seems to have absolutely no interest in Linux
(although they do provide links to some drivers for Linux on their web
site) and hence don't seem to think releasing such trivial things as how
to read the sensor chip is necesary.

On the other hand their boards tend to work very well, including with
