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.

Installing Memory Modules (DIMM)
°is motherboard provides four 288-pin DDR4 (Double Data Rate 4) DIMM slots,
and supports Dual Channel Memory Technology.
AMD non-XMP Memory Frequency Support
Ryzen Series CPUs (Matisse):
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 first
for better DRAM compatibility on 2 DIMMs configuration.
