2.3 Installation of Memory Modules (DIMM)
This motherboard provides eight 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.
