1-5 Installing an Expansion Card
Read the following guidelines before you begin to install an expansion card:
•
Make sure the motherboard supports the expansion card. Carefully read the manual that came
with your expansion card.
•
Always turn off the computer and unplug the power cord from the power outlet before installing an
expansion card to prevent hardware damage.
1-6 Back Panel Connectors
USB 2.0/1.1 Port
The USB port supports the USB 2.0/1.1 specification. Use this port for USB devices.
SMA Antenna Connectors (2T2R)

Use this connector to connect an antenna.
Tighten the antennas to the antenna connectors and then aim the antennas correctly for better
signal reception.
Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
1. Dual Channel mode cannot be enabled if only one memory module is installed.
2. When enabling Dual Channel mode with two or four memory modules, it is recommended that memory
of the same capacity, brand, speed, and chips be used. For optimum performance, when enabling
Dual Channel mode with two memory modules, we recommend that you install them in the DDR4_A2
and DDR4_B2 sockets.

When removing the cable connected to a back panel connector, first remove the cable from
your device and then remove it from the motherboard.
•
When removing the cable, pull it straight out from the connector. Do not rock it side to side to
prevent an electrical short inside the cable connector.
Dual Channel Memory Configuration
This motherboard provides four memory sockets and supports Dual Channel Technology. After the memory
is installed, the BIOS will automatically detect the specifications and capacity of the memory. Enabling Dual
Channel memory mode will double the original memory bandwidth.
