AGP bus speed problem (Win 98SE)

Running 3DMark2003 on my system (details below) I got a score of just 1056 points. I was also disappointed that Game Test 4 (Nature) was "not supported" by my system.
I put this down to having "only" a 550MHz PIII.

However, I just ran the SiSoft Sandra diagnostic utility which reports that the AGP bus is only running at 1X (66MHz) speed.
Can't see any BIOS settings for this.

I have checked the DRAM memory speed (66MHz) and have the latest video card drivers.

Any help would be appreciated, thanks.


System Details:
PIII 550MHz 640MB RAM Win98SE ATI Radeon 9500 64MB

the only reason for nature not being supported is lack of pixel shaders and the 9500 has them so thats pretty weird

Its only available in the pro version.

What motherboard do you have?

Knew I'd forgotten something......

Motherboard is Tyan S1854 Trinity 400

OK, that motherboard supports 4x on the AGP slot.

If your certain there is not a setting within the BIOS to change the AGP speed there must be a jumper on the motherboard. Do not ask me because i do not know...

Consult the motherboard maunal if you have one or click here and take a peek...

Also update the graphics card driver... click here

I meant to say "do not ask me where the jumper is, because i do not know...

Thanks for the links, Powerless.

I'd already looked at the Tyan site, but I did get newer drivers - ATI Catalyst 03.1 (I had 03.0)

In Radeon 9500 properties, it is confirmed that the AGP bus speed IS set to AGP 1X.

There is a bios setting to enable AGP "4X mode"
It was/is already set enabled.

Bit of a mystery this , eh ?

Just needed the VIA 4-in-1 drivers installed !

BTW, the Nature Test (3DMark2003) now runs along with the 'Elephant' Shader test AND I increased my score by 50% overall !!!
