1-7 Configuring an ATI CrossFireXTM System To enable CrossFireXTM 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 CrossFireX 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: Windows Vista and Windows XP. C. BIOS Settings: Before configuring your system for CrossFire X, 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 CrossFireX Mode-Connecting Two Graphics Cards: Step 1: Observe the steps in "1-5 Installing an Expansion Card" and install the graphics cards in the PCIEX16_1 slot and the PCIEX8_1 slot. Step 2: Depending on your graphics cards, install the connecting bridges on the two cards. (Note: Procedure for enabling CrossFireX may slightly differ by graphics cards. Refer to the manual that came with your graphics cards for more information about enabling CrossFireX.) Step 3: Connect your LCD monitor cable to the DVI-I port on the graphics card on the PCIEX16_1 slot (or connect your D-Sub monitor via a DVI-to-D-Sub adapter). Graphics Card Driver Setting: After installing the graphics card driver in your operating system, access the ATI CATALYST Control Center . From the ATI CATALYST Control Center , enter the CrossFire menu and select the Enable CrossFire checkbox to complete the configuration. GA-MA790GP-UD4H Motherboard - 20 -
