voltage on K7S5A Pro

Thanks for the response "GM."

The PC seems stable (ie no unexplained crashes, lock ups, graphical
corruption etc.) so I ASSUME everything is ok, despite the low warnings.
I've actually disabled the warnings so they don't bother me, but in the end
turning the warnings off does little to resolve the problem, assuming of
course that there is a real problem (i'm most concerned about damaging
hardware, though I suspect that's highly unlikely given it's an undervoltage
problem as opposed to an overvoltage one).

I know with some motherboards you can control, at least to some extent,
voltage issues on the board, though based on everything I know about the
K7S5A that particulat board is very limited in allowing users to modify such
settings.

Correct me if I'm wrong, but it was my understanding modern AGP buses
gemnerally run at 1.5 volts, and 3.3 volt slots/busses are generally for
older generation AGP hardware. If this is true, my 1.48 volt AGP VDDQ
reading is what one would expect to see, as opposed to the value of 3.3
volts which the ASUS 9600xt 'claims' to need.

Might this be related to a power supply issue? In other words, would a more
powerful supply unitpossibly resolve this issue? My best guess is no, but I
am no expert in electronics.

Anyways, thanks again and any more input would be much appreciated.

Cheers.

I believe that most of the agp cards are specificaly slotted for the
correct voltage. In other words, they won't fit if you try them in
the wrong motherboard.<!-- ~MESSAGE_AFTER~ -->

The hardware is not likely to be damaged with a slightly low voltage. Sounds
like your system is running OK so you probably are fine. I suspect PJx is
correct that the AGP cards are designed so that you can't plug one into the
wrong socket. I don't know this for a fact, but it certainly seems likely.
