AMD CrossFire™ (Multi-GPU) Technology

AMD CrossFire™ is a multi-GPU performance gaming platform. By linking together two or more discrete GPUs, CrossFire™ can significant improve system graphics performance. It allows the ability to scale a system’s graphics power as needed, making it the most scalable gaming platform. This mainboard will automatically detect CrossFire™ technology and make changes in the BIOS as needed. Follow the instructions below to ensure a successful two-way CrossFire™ installation.

1.Install two AMD Radeon™ HD graphics cards into the PCI_E2 & PCI_E5 expansion slots.

2.With the two cards installed, two CrossFire™ Video Link cable are required to connect the graphics cards. Attach one side of the cable on each of the cards by way of the metal contacts (please refer to the picture below). Please note that although two graphics cards have been installed, only the display ports on the graphics card installed in the first PCIe x16 slot will work. All displays should be connected to this graphics card.
