This motherboard provides four 288-pin DDR4 (Double Data Rate 4) DIMM slots, and

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.

*Since installing three memory modules is NOT supported on this motherboard, we suggest not using
this configuration.
The DIMM only fits 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.
