2.3 Installation of Memory Modules (DIMM)
This motherboard provides four 288-pin DDR4 (Double Data Rate 4) DIMM slots, and
supports Quad Channel Memory Technology.
1. For quad channel configuration, 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. 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.
