1. What combination of products are required to build a working
CrossFire™ system?
Three components are required:
• a CrossFire™ Edition graphics card that works as the Master
graphics card.
• a CrossFire™ Ready graphics card from the same brand-family
that works as the Slave graphics card.
• a CrossFire™ Ready motherboard (which contains two PCIe™
X16 slots).
2. What graphics cards work with CrossFire™?
A CrossFire™ graphics card works with all members of the same
brand-family. Thus a ATI Radeon™ HD 3800 CrossFire™ Edition
can be used as the Master graphics card with any ATI Radeon™ HD
3800 product.
3. What motherboard is required for a CrossFire system?
AMD 790FX, AMD 790X, CrossFire Xpress 3200, Radeon Xpress
200 CrossFire, Intel 955X, Intel 975X, Intel P965 and P35 based dual-
slot motherboards are supported platforms.
4. When will CrossFire Ready motherboards be available?
CrossFire Xpress 3200 and Radeon Xpress 200 CrossFire
motherboards are available from our partners now.
5. Are there specific CMOS motherboard settings for CrossFire™?
On some motherboards, the CMOS may be set by default to support
only a single PCI Express® X16 slot. Ensure that both PCIe™ X16
slots are enabled in the CMOS.
