PCIe 3.0/2.0 x16_1
x16 (single VGA
recommended)
In single VGA card mode, use the PCIe 3.0/2.0 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™.
Connect a chassis fan to the motherboard connector labeled CHA_FAN1/2/3 when
using multiple graphics cards for better thermal environment.
The PCIe x1_1 and PCIe x1_2 slots share bandwidth with the PCIe x16_2 slot.
The PCIe x16_2 slot runs at x2 mode as default. Please check BIOS for more
configuration..
