Is anyone run an 8x agp video card on an older 4x agp motherboard slot?
I can''t seem to get a straigt answer from ATI or ASUS.

I have run an ATI 9600 and 9700 Pro (both 8x) video cards on a P4T-E
(Asus 4x AGP) motherboard. Never had any problems.

Michael, any idea why I can't get my x850 to run? When I boot up with
it in, after loading windows, the screen goes blank. Can't do anything
but power off. When I replace it with the Radeon 8500, it will boot
right up without any problems.

I would say 99% percent of the X8 AGP cards also work at AGP X4
Does the X850 come with the secondary power connection?
If so, is it plugged in?
(Could be a 4 or 6 pin connection)

Yes I'm successfully running an x850 in an Intel 850emv mobo (agp 4x
max). Are you getting any video at all at bios boot? My old 8500
would not show any video at all up to the point of the windows loading
screen.

I have to agree it sounds like a driver problem. For sure you've
tried it with the native xp driver?
