• In single VGA card mode, use first the PCIe 2.0 x16_1 slot or PCIe 2.0 x16/

x8_3 slot for a PCI Express x16 graphics card to get better performance.

• In CrossFireX™ or SLI™ mode, use the PCIe 2.0 x16_1 and PCIe 2.0 x16/

x8_3 slots for PCI Express x16 graphics cards to get better performance.

• Use the PCIe x16_1, PCIe x8/x1_2, and PCIe x16/x8_3 slots for 3-Way SLI

or CrossFireX™ mode.

• If you install a PCIe x16 graphics card on to the PCIe x16_1 slot, a PCIe

device with a bandwidth faster than x8 link to the PCIe x16/x8_3 slot, and a

PCIe device with a bandwidth slower than x4 link to the PCIe x8/x1_2 slot,

the three PCIe x16 slots will work at x16, x16, x1 link as the default.

• If you install a PCIe x16 graphics card on to the PCIe x16_1 slot, a PCIe

device with a bandwidth slower than x8 link to the PCIe x16/x8_3 slot, and

a PCIe device with a bandwidth faster than x4 link to the PCIe x8/x1_2 slot,

the three PCIe x16 slots will work at x16, x8, x8 link as the default.

• We recommend that you provide sufficient power when running

CrossFireX™ or SLI™ mode.

• Connect a chassis fan to the motherboard connector labeled

CHA_FAN1/2/3 when using multiple graphics cards for better thermal

environment.
