baekalfen Posted April 18, 2012 Share Posted April 18, 2012 Hi! I have recently got my AMD machine to run Snow Leopard. I have everything working with my ATI 5850 for the main display, but on Windows i ran a nVidia 8600GT for my secondary display. I think I have tried every single method to make the card work, but it keeps saying this at boot: Bad display config block signature (0x8b262275) ERROR: nVidia ROM patching failed! The computer still works, but without the second monitor or the nVidia graphics card active. My System: CPU: Amd Phenom II x4 965 (OC'ed but 100% stable) MOBO: Gigabyte MA790GPT-UD3H GFX: XFX ATI 5850 1GB (OC'ed but 100% stable) GFX: Inno3D nVidia 8600GT 1GB RAM: 3x 2Gb OCZ 1333Mhz cl7 Link to comment Share on other sites More sharing options...
