2.7 CrossFireXTM and Quad CrossFireXTM Operation Guide

This motherboard supports CrossFireXTM and Quad CrossFireXTM. CrossFireXTM 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, CrossFireXTM enables the highest possible level of performance and image quality in any 3D application. Currently CrossFireXTM is supported by Windows® XP with Service Pack 2 / VistaTM / 7 OS. Quad CrossFireXTM is supported by Windows® VistaTM / 7 OS only. Please check AMD’s website for AMD 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 CrossFireXTM Edition card with a 16-pipe card, both cards will operate as 12-pipe cards while in CrossFireXTM mode.

2.7.1Installing Two CrossFireXTM-Ready Graphics Cards

Step 1. Insert one Radeon graphics card into PCIE1 slot and the other Radeon graphics card to PCIE2 slot. Make sure that the cards are properly seated on the slots.
