The four memory sockets are divided into two channels and each channel has two memory sockets as following:
Channel A: DDR4_A1, DDR4_A2
Channel B: DDR4_B1, DDR4_B2
*Recommended Dual Channel Memory Conguration:
DDR4_A1 DDR4_A2 DDR4_B1 DDR4_B2
2 Modules - - DS/SS - - DS/SS
4 Modules DS/SS DS/SS DS/SS DS/SS
(SS=Single-Sided, DS=Double-Sided, "- -"=No Memory)
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.
When installing a single memory module, we recommend that you install it in the DDR4_A2
or DDR4_B2 socket.

•These an headers are not conguration jumper blocks. Do not place a jumper cap on the headers.
3/4) CPU_FAN/SYS_FAN1/2/3 (Fan Headers)
All fan headers on this motherboard are 4-pin. Most fan headers possess a foolproof insertion design.
When connecting a fan cable, be sure to connect it in the correct orientation (the black connector wire is
the ground wire). The speed control function requires the use of a fan with fan speed control design. For
optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.
