• We recommend that you provide sufficient power when running CrossFireX™ or SLI™
mode.
• Connect a chassis fan to the motherboard connector labeled CHA_FAN1-4 when
using multiple graphics cards for better thermal environment.
• For a higher performance of the 3-Way configuration using the 40-LANE CPU, adjust
the bandwidth of the PCIe x16_5 slot to x8 mode in BIOS. Refer to Chapter 3 for more
information.
