My new ATI Radeon 9700 PRO will not work at 8x AGP. Everytime I run 3DMark2001SE, the system will freeze about 5-6 minutes through the benchmark everytime. I backed the AGP speed down to 4x and the problem goes away.
Any suggestions as to how I can get my card running at 8x AGP.... I know the performance I am losing isnt huge but approximately how much of a difference is there between 8x and 4x AGP using this card?

Have you tried flashing mobo your bios? Newest drivers? Dx9.0a? There is a newer version of 3d mark 2001se that enables testing of agp 8x, have you using it? Does it freezes only in 3dmark or in every 3d game?
Do you have fast writes enabled? That's another source of potential conflict, and it seems to produce neglible differences on benchmarking (absolutely no diff in my case). I've benchmarked my 9500 Pro at both 4X and 8X on an Asus A7V8X, and have not found a significant difference (i.e. less than 1%), so it shouldn't matter for you anyway.
