1. For dual channel configuration, you always need to install identical (the same
brand, speed, size and chip-type) DDR4 DIMM pairs.
2. It is unable to activate Dual Channel Memory Technology with only one or three
memory 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.
4. We suggest that you install the memory modules on DDR4_A2 and DDR4_B2 for
Dual Channel Memory Technology.
