Installing Three Crossfirex; Ready Graphics Cards - ASROCK 990FX Extreme9 User Manual

2.6.1.2 Installing Three CrossFireX

Step 1. Install the identical 3-Way CrossFireX
AMD certified because different types of graphics cards will not work to-
gether properly. (Even the GPU chips version shall be the same.) Insert
one graphics card into PCIE1 slot, another graphics card to PCIE4 slot,
and the other graphics card to PCIE5 slot. Make sure that the cards are
properly seated on the slots.
Step 2. Use one CrossFire
and PCIE4 slots, and use the other CrossFire
graphics cards on PCIE4 and PCIE5 slots. (CrossFire
with the graphics card you purchase, not bundled with this motherboard.
Please refer to your graphics card vendor for details.)
Step 3. Connect the DVI monitor cable to the DVI connector on the Radeon graph-
ics card on PCIE1 slot. (You may use the DVI to D-Sub adapter to convert
the DVI connector to D-Sub interface, and then connect the D-Sub monitor
cable to the DVI to D-Sub adapter.)
