2.6.1 Graphics Card Setup
2.6.1.1 Installing Two CrossFireX TM -Ready Graphics Cards
Different CrossFireX TM cards may require different methods to enable CrossFi-
reX TM feature. In below procedures, we use Radeon HD 3870 as the example
graphics card. For other CrossFireX TM cards that AMD TM has released or will
release in the future, please refer to AMD TM graphics card manuals for detailed
installation guides.
Step 1. Insert one Radeon graphics card into the PCIE2 slot and the other Rad-
eon graphics card to the PCIE3 slot. Make sure that the cards are properly
seated on the slots.
1. If a customer incorrectly configures their system they will not see the
performance benefits of CrossFireX TM . All three CrossFireX TM components, a
CrossFireX TM Ready graphics card, a CrossFireX TM Ready motherboard and a
CrossFireX TM Edition co-processor graphics card, must be installed correctly
to benefit from the CrossFireX TM multi-GPU platform.
2. If you pair a 12-pipe CrossFireX TM Edition card with a 16-pipe card, both
cards will operate as 12-pipe cards while in CrossFireX TM mode.
