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_3
DDR4_4
DDR4_1
DDR4_6
DDR4_2
