System Memory
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.
Dual Channel (DC)
Data will be accessed in chunks of 128 bits from the memory channels. Dual channel provides
better system performance because it doubles the data transfer rate.
Single Channel
DIMMs are on the same channel. DIMMs in a channel can be identi-
cal or completely different. However, we highly recommend using
identical DIMMs. Not all slots need to be populated.
Dual Channel
DIMMs of the same memory configuration are on different channels.
DDR4_1
DDR4_2
Installing the SO-DIMM Module
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 SO-DIMM vertical socket on the system board
4. Make sure the notch on memory card is aligned to the key on the socket.
