ASRock P45X3 Deluxe Quick Installation Guide - Page 17

Enjoy the benefit of CrossFireXTM Different CrossFireXTM cards may require different methods to enable CrossFireXTM feature. In below procedures, we use Radeon 4850 as the example graphics card. For other CrossFireXTM cards that ATITM has released or will release in the future, please refer to ATITM graphics card manuals for detailed installation guide. Step 1. There is one ASRock SLI/XFire Switch Card factory-mounted on this motherboard. This card served as a switch between the default mode (x16) and CrossFireXTM mode (x8 / x8). ASRock SLI/XFire Switch Card is factory-mounted with its default mode (x16) side toward the retention slot base. Step 2. To change it to CrossFireXTM Mode, you need to reverse the direction of ASRock SLI/XFire Switch Card. Please simultaneously pull open both the retention arms that hold the card in position. The card itself will spring away from the retention slot. Take it out gently by holding its edges, and keep away from touching the connectors (Golden Fingers). Step 3. Reverse the card direction so as to have the "X8 / X8 MODE" wording side toward the retention slot base. Insert the card into the bottom of the base. English 17 ASRock P45X3 Deluxe Motherboard
