5900XT running at 4x not 8x

[MarcEG]

Hi, got a Gigabyte 5900XT (supports AGP speed 8x) and an Abit mobo (KD7-G) supports upto 8x. When I click the gigabyte VGA Utility in the tooltray and select VGA Information it states that the AGP Speed is 4x.
I have entered the BIOS of the mobo and I cannot change the AGP speed (although I can if I put in my old Ti200 Geforce). I have the latest BIOS for both GPU & Mobo so I am now at a loss as to why its not running at 8x, any help greatly appreciated

It could be a faulty utility report.

There is hardly any difference between the two modes anyhow.

Have you tried benchmark tests? -

Have you updated the chipset drivers for the mobo too?

Don't worry about it.

Some BIOS do have setting for that.

In my experience there is a huge difference between 4 and 8x. Make sure in your BIOS that your motherboard is allowing 8X and not 4X.
