• We recommend that you provide sufficient power when running CrossFireX™ or SLI® mode.

•Connect a chassis fan to the motherboard connector labeled CHA_FAN1-3 when using multiple graphics cards for better thermal environment.

•4th generation Intel® Core™ processors support PCIe 3.0 speed rate.

• When the system is running with four VGA cards, ensure to connect the EZ PLUG_1/2 for extra PCIe power supply.

•PCIe 3.0/2.0_x16/x8_1 slot switches to x8 mode when other PCIe 3.0/2.0 slots are occupied.

•PCIe 3.0/2.0_x8_B2 slot will be disabled when PCIe 3.0/2.0_x16_A2, PCIe 3.0/2.0_ x8_3, PCIe 3.0/2.0_x8_4 slots are occupied.
