B. Connecting the Graphics Cards
Step 1:
Observe the steps in "1-5 Installing an Expansion Card" and install CrossFire/SLI graphics cards on the PCI Express x16
slots. (To set up a 2-Way con��guration, we recommend installing the graphics cards on the PCIEX16_1 and PCIEX16_2 slots.)
Step 2:
Insert the CrossFire
/SLI bridge connectors in the CrossFire/SLI gold edge connectors on top of the cards.
(Note)
Step 3:
Plug the display cable into the graphics card on the PCIEX16_1 slot.
C. Con��guring the Graphics Card Driver
C-1. To Enable CrossFire Function
After installing the graphics card driver in the operating system, go to
the Catalyst Control Center. Browse to Performance\AMD CrossFi-
