Help! I got some a lot of 3 radeon 9600 SE cards off ebay. I WANTED one in a tyan trinity 400 system..... that's an apollo pro chipset. I drop the card in and..................... nothing. No beeps, no POST, no nothing.

At first I though the cards were bad. Then I tried them in on an ASUS A7V600 board... and no problem.

But here is the funny part.... I used to use a Radeon9600 (not the SE version) with that same board and it worked fine. What gives? Did the SE cards come later and will only work in 8X AGP boards?
