ATI CROSSFIREX TECHNOLOGY DRIVERS
Normally the CrossFire drivers are included in the generic AMD Graphics Card drivers which you can download on the AMD website. You do require drivers for CrossFire for setting up a multi-GPU configuration for AMD Graphics Cards. AMD Radeon Graphics cards that do not require CrossFire communicate through PCI Express Lanes or Bus. But most of the older generation AMD Radeon graphics cards require CrossFire Bridge for working in Crossfire. Not all AMD graphics cards, especially the latest ones, require CrossFire Bridge for CrossFire Configuration. Not all motherboards having multiple PCI Express x16 graphics card slots support Crossfire as some of them support SLI only. The other major requirement of Crossfire setup is Crossfire Ready Motherboard or Motherboard that supports CrossFire.
You can look at the compatibility list below of CrossFire graphics cards showing which AMD graphics cards are compatible with another in CrossFire configuration. Unlike Nvidia SLI, two graphics cards having different GPUs may work together in AMD CrossFire mode depending on their compatibility. The first requirement for setting up a CrossFire configuration is two or more CrossFire Ready AMD Graphics Cards (up 4 GPUs). Here are the various requirements for setting up a CrossFire setup on your computer using multiple GPUs.
