ATI Radeon 9550 works on some mobos but not on others

[byro73]

I have recently acquired an old ATI Radeon 9550 Graphics card but i can't get it to work on my MSI 865 PE neo 2 mobo . It works fine on my older Intel 815 mobo

I used to own the exact same card. It is AGP x8 compatible only! It does not support AGP x2 or x4 motherboards!
Hope that helps!

Thanks Rik from RCE. I checked the MSI 865 mobo's manual and it states that it supports
AGP x8. Any other suggestions
