Motherboard Incompatibility?

[asianmaster]

Some friends and I just made up a computer for my younger brother; it has been working fine with the one exception of video card compatibility. The computer is running on a Seperon 2800+ with an ECS K7VTA3 motherboard (nothing fancy I admit by any means). Anyway, we originally purchased a Radeon 9600LE to go in it but it didn?t work. Now I?ve been trying to get it to run with a new 9550 and it doesn?t want to take that either, just the old Radeon 9000 that I got from a friend. When I turn on the computer with either the 9600 or 9550 they monitor continues to register ?no feed.? The computer seems to be booting up and proceeding as usual. I just don?t get a visual feed. It works just fine with the 9000; I just want to put a better card in it. Does anyone have an idea of what the problem might be? Someone suggested that the mobo might not be giving the card enough power but I tried unplugging everything and running it and it still doesn?t work. I doubt that it is an incompatibility issue as large as ?no radeons.? Anyway, any help would be appreciated. Thanks guys

I'm not sure what the problem is but make sure you have the latest BIOS and latest VIA AGP driver. Check the motherboard BIOS for the following options (I don't know if they're there in this board):

1) AGP Fastwrites, disable it;

2) set AGP to 4x;

3) If there's an AGP voltage setting, set it to 1.6V.

When getting the latest BIOS make sure you get the right one for your board. There are two K7VTA3, check the version number on yours.

The board is not compatible with the 9600 series and it's cousins.

I have heard of ECS mobo's regecting Sapphire 9800 pro's but running ATI 9800 pro's just fine. Basicly, they pick what they want to run.
