(This link does not say it is for your particular board...)
If the AGP video card is 4X then it is 1.5 volt card and this is supported.
If the AGP video card is 8X then it is 0.8 volt card and this is also supported on a 1.5 volt AGP slot.
NOTE: Any AGP card that has 4x or 8x AGP support is Supported on the 1.5 volt AGP slot.
NOTE: Any AGP card that has only 1x or 2x AGP support is not Supported on the 1.5 volt AGP slot.

Check the WEB site link above for original info to be sure...

The following link seems to contradict that a little...

I would pick a card and check it specifically before installing it...
