graphics card. The result is a complete frame rendered at up to twice the performance of a single graphics card.

8How are the graphics cards connected on a CrossFire™ system?

The two cards are connected by an external cable. The cable is attached from the Slave graphics card’s DVI-I connection to the CrossFire™ Edition’s DMS-59™/VHDCI connection, which is used to convey information from the Slave graphics card to the Master graphics card and transmit the combined signal to a display device.

9Which games/applications work with CrossFire™?

CrossFire™ works with all full-screen 3D games and applications. If Catalyst™ A.I. is enabled in the Catalyst™ Control Center software, the optimal rendering mode available for the application is automatically selected.

10Is a driver profile required to make CrossFire™ work?

No. CrossFire™ is enabled by default for all full-screen 3D games and applications.

11What happens if you pair a 16-pipeline CrossFire™ Edition graphics card with a CrossFire™ Ready 12-pipeline graphics card?

In this scenario both graphics cards will operate as 12-pipeline graphics cards while in CrossFire™ mode.

12What happens if the CrossFire™ Edition graphics card and the CrossFire™ Ready graphics card have different clock speeds?

Both cards will continue to operate at their individual clock speeds; neither card is “stepped down.” The compositing engine on the CrossFire™ Edition card merges the resulting images independent of the clock speed on either graphics card.

13What are the rendering modes, and what are their specific advantages?

The following dynamic rendering modes are available:

•SuperTiling - CrossFire™ renders alternate 32x32 pixel squares in a fine-grained checkerboard pattern. This configuration increases the performance, as each card processes half of the complex 3D objects in the pixel squares.
