In single VGA card mode, use first the PCIe 2.0 x16_1 slot (blue) or PCIe
2.0 x16_2 slot (blue) for a PCI Express x16 graphics card to get better
performance.
In CrossFireX™ or SLI™ mode, use the PCIe 2.0 x16_1 (blue) and PCIe
2.0 x16_2 (blue) slots for PCI Express x16 graphics cards to get better
performance.
Use the three PCIe 2.0 x16 slots for Triple CrossFireX™ or 3-way SLI™
mode.
We recommend that you provide sufficient power when running
CrossFireX™ or SLI™ mode. See page 2-36 for details.
Connect a chassis fan to the motherboard connector labeled CHA_FAN1/2
when using multiple graphics cards for better thermal environment. See
page 2-34 for details.
