2.6 CrossFireXTM and 3-Way CrossFireXTM Operation Guide This motherboard supports CrossFireXTM and 3-Way CrossFireXTM feature. CrossFireXTM and 3-Way CrossFireXTM technology offer 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, CrossFireXTM and 3-Way CrossFireXTM enable the highest possible level of performance and image quality in any 3D application. Currently CrossFireXTM feature is supported with Windows® XP with Service Pack 2 and VistaTM OS, and 3-Way CrossFireXTM feature is supported with Windows® VistaTM OS. Please check AMD website for ATITM CrossFireXTM and 3-Way CrossFireXTM driver updates. 1. If a customer incorrectly configures their system they will not see the performance benefits of CrossFireXTM. All three CrossFireXTM components, a CrossFireXTM Ready graphics card, a CrossFireXTM Ready motherboard and a CrossFireXTM Edition co-processor graphics card, must be installed correctly to benefit from the CrossFireXTM 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 CrossFireXTM mode. 2.6.1 Graphics Card Setup 2.6.1.1 Installing Two CrossFireXTM-Ready Graphics Cards Different CrossFireXTM cards may require different methods to enable CrossFireXTM feature. In below procedures, we use Radeon HD 3870 as the example graphics card. For other CrossFireXTM cards that ATITM has released or will release in the future, please refer to ATITM graphics card manuals for detailed installation guide. Step 1. There is one ASRock SLI/XFire Switch Card factory-mounted on this motherboard. This card served as a switch between the default mode (x16) and CrossFireXTM mode (x8 / x8). ASRock SLI/XFire Switch Card is factorymounted with its default mode (x16) side toward the retention slot base. English 22 ASRock M3A780GXH/128M Motherboard
