Chapter 1: Product introduction
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.
Hyper M.2 X16 card is purchased separately.
Enable the Hyper M.2 X16 card under BIOS settings.
