System Memory; Installing The Dimm Module - DFI CS650-C246 User Manual

X System Memory
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.
