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

this conguration.

1. 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.

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

speed, size and chip-type) DDR4 DIMMs.

3. It is required to install four memory modules to activate Quad Channel Memory Tech-

nology.

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.
