Features
The system board supports the following memory interface.
Single Channel (SC)
Data will be accessed in chunks of 64 bits from the memory channels. DIMMs are on the same
channel. DIMMs in a channel can be identical or completely different. However, we highly rec-
ommend using identical DIMMs. Not all slots need to be populated.
DDR4_5
DDR4_7
DDR4_6
Before installing the memory module, please make sure that the following safety cautions are
well-attended.
1. Make sure the PC and all other peripheral devices connected to it has been powered
down.
2. Disconnect all power cords and cables.
3. Locate the DIMM socket on the system board
4. Make sure the notch on memory card is aligned to the key on the socket.

Important:
CH-A: DIMM 1, 2 CH-B: DIMM 3, 4
CH-C: DIMM 5, 6 CH-D: DIMM 7, 8
While only one DIMM is installed in a channel, it should be installed in even num-
ber DIMM (DIMM 2/4/6/8).
