2.3 Installation of Memory Modules (SO-DIMM) This motherboard provides four 260-pin DDR4 (Double Data Rate 4) SO-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 SO-DIMM pairs. 2. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4 slot; otherwise, this motherboard and SO-DIMM may be damaged. 3. The SO-DIMM only fits in one correct orientation. It will cause permanent damage to the motherboard and the SO-DIMM if you force the SO-DIMM into the slot at incorrect orientation.

If only two memory modules are installed in the DDR4 SO-DIMM slots, then Dual
Channel Memory Technology is activated. If three memory modules are installed, then
Triple Channel Memory Technology is activated.
1. For quad channel configuration, you always need to install identical (the same
brand, speed, size and chip-type) DDR4 SO-DIMM pairs.
2. It is not allowed to install a DDR, DDR2 or DDR3 memory module into a DDR4
slot; otherwise, this motherboard and SO-DIMM may be damaged.
3. °e SO-DIMM only fits in one correct orientation. It will cause permanent damage
to the motherboard and the SO-DIMM if you force the SO-DIMM into the slot at
incorrect orientation.
