5Which slot does the CrossFire™ Master card go into on the motherboard?

The CrossFire™ Master card must go into the primary PCI Express® slot (slot zero) on the motherboard.

Note: To determine which PCIe™ slot is the primary slot, consult your motherboard manual.

Alternately, to determine whether or not a CrossFire™ Edition card is in the correct slot, connect your display directly to the DVI-I connection on the Master graphics card instead of using the CrossFire™ DMS-59™/VHDCI connector, with both graphics cards seated in their respective slots on the motherboard. If an image appears on the screen upon boot-up, the card has been placed in the primary slot on the motherboard.

6Are there any software settings required for CrossFire™ to work?

Yes, there is a setting in the Catalyst™ Control Center that needs to be enabled for CrossFire™ to operate. When all of the hardware and software has been properly set up and installed, the CrossFire™ aspect appears in Catalyst™ Control Center:

To access and enable CrossFire™ in Catalyst™ Control Center, do the following:

•Click CrossFire™ in Advanced View. Then, select Enable CrossFire™.

When CrossFire™ is successfully enabled, all display devices except the one used by CrossFire™ will be disabled. Multiple monitors/ displays that are disabled when CrossFire™ is enabled reappear after CrossFire™ is disabled.

To change to Advanced View:

•Click the Dashboard View button and select Advanced View.

•Select Displays Manager in the tree view.
