Chapter 2
• In single VGA card mode, use first the PCIe 2.0 x16_1 slot (blue) for a PCI Express x16
graphics card to get better performance.
• We recommend that you provide sufficient power when running CrossFireX™ mode.
See page 2-32 for details.
• The PCIe x1_2 slot shares the bandwidth with the PCIe x16_2 slot. Due to the
CrossFireX™ limitation, DO NOT use the PCIe x1_2 slot when you install two
CrossFireX™ graphics cards on both the PCIe x16 slots to set up a CrossFireX™
configuration.
• Connect a chassis fan to the motherboard connector labeled CHA_FAN when using
multiple graphics cards for better thermal environment. See page 2-30 for details.
