Stuck on 1X AGP mode

[mr0range]

I've got a MSI K7N415 motherboard (Socket A, nforce1 chipset) with an 1.7Ghz Athlon XP and a Radeon 9800 Pro hooked up. However, from what SiSoft and the ATI Catalyst Control Center say, and judging from 3D performance (or lack thereof), it seems the card is stuck at the 1X AGP data rate. I went into the BIOS and changed the AGP Bus setting from Auto to Manual->Strongest (there is no option to explicitly set it to 4X) but the board supports 1X-4X speeds. I reinstalled the chipset drivers from MSI, then installed the unified nForce driver from nVidia, all to no avail. Does anyone know what is going on, and how the hell I can get this card running at 4X? Thanks

did you try updating the bios? and maybe in windows if you go to advanced display properties, also the SMARTGART tab it should let you adjust the agp speed

Ran smartgart, but there is no tab/option for setting AGP speed

What size is the AGP aperture set to, i think when u set it at 32 or lower AGP stops working in any mode but 1x
