Step 1. Install identical 4-Way CrossFireX

properly. (Even the GPU chips version shall be the same.) Insert one
graphics card into PCIE1 slot, another graphics card into PCIE3 slot, the
third graphics card into PCIE5 slot and the last graphics card into PCIE7
slot. Make sure that the cards are properly seated on the slots.
Step 2. Use one CrossFire
TM
Bridge to connect the Radeon graphics cards on
PCIE1 and PCIE3 slots, another CrossFire
TM
Bridge to connect the Rad-
eon graphics cards on PCIE3 and PCIE5 slots, and use the third Cross-
Fire
TM
Bridge to connect the Radeon graphics cards on PCIE5 and PCIE7
slots. (The CrossFire
TM
Bridge is provided with the graphics card you pur-
chase, not bundled with this motherboard. Please refer to your graphics
card vendor for details.)
