brand, speed , size and chip-type) DDR4 DIMM pairs.
2. It is unable to activate Dual Channel Memor y Technology with only one or three
memor y module installed.
3. 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.
e DIMM only ts in one correct orientation. It will cause permanent dam age to
