Hi..I bought this motherboard GA-MA785GMT-UD2H it has a ATI 4200 built in..and the board says i can crossfire this..its onboard..and i put in another ATI 4850 1 GB and i wanted to crossfire these two but afte installing catalyst i cant find the "crossfire" option in the graphics menu. some help would be appreciated.. thanks :sarcastic:
 
the board supports "hybrid crossfire" which is very different from normal crossfire, it is only really useful when using a low end card as the IGP is very week and will provide no gain and may even provide a performance hit since the CPU has to feed 2 GPUs. The HD 4200 is about as strong as an HD 2600 discrete card, it will provide you no benefit.

thats ok..i just wanted to see how it would work..the xfx ati 4850 i have is
crossfire x and would be helpful if i could just try it out..i just cant find the crossfire option in graphics menu
 
The hybrid crossfire won't work with the HD4850. Hybrid crossfire to the best of my knowledge only works with the HD3450 and HD3470 model graphics cards. I also wished that hybrid crossfire would work with other 4000 series cards, but after a lot of research I found this to not be the case.

Even if you could get it to "work", it would not be beneficial to you as the onboard graphics are quite a lot slower than the HD4850.

For crossfire X you would need to have a second HD4850, and a second PCI-x slot (16X). I am unsure if your board has this, but I doubt it. Your HD 4850 is crossfire x CAPABLE, but unless you have a second card that functionality will not be available.
