*Since installing three memory modules is NOT supported on this motherboard, we suggest not using

this conguration.

1. For dual channel conguration, you always need to install identical (the same brand,

speed, size and chip-type) DDR4 DIMM pairs.

2. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4 slot;

otherwise, this motherboard and DIMM may be damaged.

3. Please install the memory module on CH0_A1 for the rst priority.

4. To activate Dual Channel Memory Technology, please follow the “Dual Channel Memory

Conguration” table below.

e DIMM only ts in one correct orientation. It will cause permanent damage to the

motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation.
