ATI 9800 Pro will only Run 4x on my Asus PC-DL Dual Xeon System - HELP!

[KiTT]

My problem is that my graphics card will only run in 4x not 8x.

My system is based on the ASUS PC-DL Deluxe Dual Xeon Motherboard with
2 x 3.06Ghz CPUs & 8x AGP slop. I have 2 x 512Mb PC2700 (PC333)
Memory. 2 x 160Gb SATA Harddrives (Raid 0). My graphics card is an
ATI 9800 Pro (128Mb).

My OS is Windows XP Pro (For my sins)

I have the latest 1003 BIOS from Asus.
I downloaded the latest drivers for the graphics card (as of today).

I enter the display setup, go to the tab that refers to AGP speed
(can't remember that tab name.). The slider shows it is set to 4x. I
slide it to 8x and apply. Windows XP asks me to reboot, I say yes.
Upon reloading the screen is slow to update and after a few seconds
flickers and stablises. I enter the display setup again and the
slider has returned to 4x!

I am a systems engineer with many years experience (not to say I don't
mess up once in a while) but I am *fairly* confident it is nothing
related to jumper settings or "is it plugged in right?"

I would love to fix this issue as it is really bugging me that I have
spent £250 on a card that isn't running at its full potential.

Is my graphics card compatible with my motherboard?

Your help would be greatly welcomed.

Don't worry about it, thats enough, performance is not being restricted more
than the odd percent or two.
