Asus P8P67 LE - Manual (Page 36)

ASUS P8P67 LE 1-24
• In single VGA card mode, use 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 1-30 for details.
• Connect a chassis fan to the motherboard connector labeled CHA_FAN1 or CHA_FAN2
when using multiple graphics cards for better thermal environment.
• The PCIe x1 slots share the bandwidth with the PCIe x16_2 slot. Due to the
CrossFireX™ limitation, DO NOT use the PCIe x1 slots when you install two
CrossFireX™ graphics cards on both the PCIe x16 slots to set up a CrossFireX™
configuration. To disable the PCIe X1 slot, refer to the Onboard Devices Configuration
section in the BIOS for details.
