What graphics cards work with CrossFireTM? A complete CrossFireTM system requires a CrossFireTM Ready motherboard, a CrossFireTM Edition graphics card and a compatible standard Radeon (CrossFireTM Ready) graphics card from the same series, or two CrossFireTM Ready cards if they are software enabled. This applies to cards from ATI or any of its partners. Cards For AGI Express Slot Radeon X1800 Series Radeon X1600 Series Radeon X1300 Series Radeon X850 Series Cards For PCI Express Slot Radeon X1800 CrossFireTM Edition Radeon X1600 Series Radeon X1300 Series Radeon X850 CrossFireTM Edition 1. If a customer incorrectly configures their system they will not see the performance benefits of CrossFireTM. All three CrossFireTM components, a CrossFireTM Ready graphics card, a CrossFireTM Ready motherboard and a CrossFireTM Edition co-processor graphics card, must be installed correctly to benefit from the CrossFireTM multi-GPU platform. 2. If you pair a 12-pipe CrossFireTM Edition card with a 16-pipe card, both cards will operate as 12-pipe cards while in CrossFireTM mode. Enjoy the benefit of CrossFireTM Currently, ATI has released Radeon X850XT, X1800XT, X1300, and X1600 CrossFireTM cards, which require different methods to enable CrossFireTM feature. In the below procedures, we use Radeon X850XT as the example graphics card. For other CrossFireTM cards that ATI has released or will release in the future, please refer to ATI graphics card manuals for detailed installation guide. Step 1. Adjust the jumpers on this motherboard to enable AGI Express slot (PCI Express x 4). Please refer to the pictures below for proper jumper setting. PCIEx1_EN1-4: Short Pin1, Pin2 PCIEx1_EN5: Short Pin1, Pin2 Step 2. Connect to the system power supply. Please connect a hard disk power connector to SLI/XFIRE Power connector. It is recommended to use 500-Watt power supply or greater to perform the benefit of CrossFireTM feature for Radeon X850XT. 20
