• In single VGA card mode, use the PCIe 3.0 x16_1 slot (gray) for a PCI Express x16
graphics card to get better performance.
• We recommend that you provide sufficient power when running CrossFireX™ mode.
• Connect a chassis fan to the motherboard connector labeled CHA_FAN1/2 when
using multiple graphics cards for better thermal environment.
When using PCI cards on shared slots, ensure that the drivers support “Share IRQ” or that
the cards do not need IRQ assignments. Otherwise, conflicts will arise between the two PCI
groups, making the system unstable and the card inoperable.
