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.
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.
