If this is a Gigabyte board, you can try here: http://tw.giga-byte.com/Motherboard/Support/Driver/Driver_List.htm to find the software to install to turn your AGP from 1X to 2X. These should be somewhere on the CD used to install your motherboard. They will be referred to as:
 
These drivers may be referred to using any of the following names:
 
* AGP Driver
* AGP Miniport
* AGP VXD Driver
* Chipset Driver
* GART Driver
* VGART
 
Often you will see the name of a motherboard chipset in connection with these terms. For example:
 
* ALi GART Driver
* AMD AGP Miniport
* Intel VGART
* VIA AGP Driver
 
 

well i dont have the CD, on the site you gave me, the agp driver is already to the latest one i have, but there is also a EIDE driver there in the setup, so i installed that, i dont know what it does, but is there any other ways i can get the AGP running at 2X?
 
thanks

Sorry to get back to you so late. Went to Gigabyte myself to see what was up. Obviously, this board came out post-XP and Gigabyte claims that the AGP drivers are given in XP. What you are looking for is the AMD AGP miniport drivers. Under 95,98, ME and 2000 these were installed separately. Try this utility that can be downloaded from here: http://www.amd.com/us-en/assets/content_type/utilities/AMDdrvpk_130.exe
It is the AMD power drive pack that should look at your system and help you put the miniport driver in to change it to 2X.
Also Powerstrip should be able to for do it, but you would have to do this after each bootup.

it works now, thanks a lot for your help
