In single VGA card mode, use the PCIe 3.0 x16_1 slot (beige) for a PCI Express x16
graphics card to get better performance.
In CrossFireX™ or SLI™ mode, use the PCIe 3.0 x16_1 and PCIe 3.0 x16_3 slots for
PCI Express x16 graphics cards to get better performance.
In 3-way SLI mode, use the PCIe 3.0 x16_1/PCIe 3.0 x16_3/PCIe 3.0 x16_4 slots for
PCI Express x16 graphic cards to get better performance.
We recommend that you provide sufficient power when running CrossFireX™ or SLI™
mode.
Connect a chassis fan to the motherboard connector labeled CHA_FAN1/2 when
using multiple graphics cards for better thermal environment.
