2.7 CrossFireTM Operation Guide This motherboard supports CrossFireTM feature. CrossFireTM technology offers the most advantageous means available of combining multiple high performance Graphics Processing Units (GPU) in a single PC. Combining a range of different operating modes with intelligent software design and an innovative interconnect mechanism, CrossFireTM enables the highest possible level of performance and image quality in any 3D application. Currently CrossFireTM feature is supported with Windows® XP with Service Pack 2 and VistaTM OS. Please check AMD website for ATITM CrossFireTM driver updates. 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. This applies to cards from ATITM or any of its partners.

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, ATITM has released Radeon X2600Pro, X2600XT, X1950Pro, X1950XTX and X1800 CrossFireTM cards, which require different methods to enable CrossFireTM feature. In below procedures, we use Radeon X2600XT as the example graphics card. For other CrossFireTM cards that ATITM has released or will release in the future, please refer to ATITM graphics card manuals for detailed installation guide. Step 1. Connect to the system power supply. Please connect a hard disk power connector to SLI/XFIRE Power connector on this motherboard. It is recommended to use 500-Watt power supply or greater to perform the benefit of CrossFireTM feature. 19
