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 only supported with Windows® XP with Service Pack 2; it may be supported with other OS in the future, such as Windows® VistaTM. Please check ATITM website for 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 if they are software enabled. This applies to cards from ATITM or any of its partners.

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.
