• In single VGA card mode, use the PCIe 2.0 x16_1 slot (navy blue) 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_2 slots for
PCI Express x16 graphics cards to get better performance.
• We recommend that you provide sufficient power when running CrossFireX™ or SLI™
mode. Refer to page 2-27 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 2-26 for details.
