English 1-6 Configuring an ATI CrossFireTM System To enable CrossFireTM technology, you need two graphics cards that support ATI CrossFireTM technology. Before You Begin-A. Power Requirements: Use a power supply that is able to provide sufficient power to fully support an CrossFire configuration and other components in your system. We recommend a power supply that provides at least 20A 12V current. The exact power requirements depend on your overall system configurations. B. Supported Operating Systems: Only Windows XP operating system is currrently supported by the ATI CrossFireTM technology. C. BIOS Settings: Before configuring your system for CrossFire, make sure to set Init Display First under Advanced BIOS Features in BIOS Setup to PEG first. (Start your system with a single PCIe x16 graphics card and then go to BIOS Setup to set Init Display First to PEG. Then install the second graphics card to enable CrossFire.) Enabling CrossFire Mode-Connecting Two Graphics Cards: Step 1: Observe the steps in "1-5 Installing an Expansion Card" and install the graphics cards in the PCIE_16 slot and the PCIE_4_1 slot. Step 2: Depending on your graphics cards, install the connecting bridges on the two cards. (Note: Procedure for enabling CrossFire may slightly differ by graphics cards. Refer to the manual that came with your graphics cards for more information about enabling CrossFire.) Step 3: Connect your LCD monitor cable to the DVI-I port on the graphics card on the PCIE_16 slot (or connect your D-Sub monitor via a DVIto-D-Sub adapter).
