Running Radeon 9200 at 8x

[FLG]

I have a Gygabyte Rade0n 9200 graphics card, and it supports AGP 8x so does my motherboard but it still will only run at 4x i enabled 8x support. Am i missing something? ive also flashed the bios of my mobo and graphics card. Im using a MSI K7N2 Motherboard.

Well since i cant edit it any more i want to clarify what i wrote (sorry fot the double post)

The Card is currently running at AGP 4x and i want to get it to run at 8x,the card and my motherboard both support 8x, i enabled 8x in my motherboards bios, and i started windows and enabled AGP 8x under the adanced properties of my display. But it still runs at 4x what am i missing here?

Im using a MSI K7N2 mobo and a Gigabyte Radeon 9200 graphics card,AMD Athlon 2400+, and windows xp.
