The system board supports the following memory interface.
Single Channel (SC)
Data will be accessed in chunks of 64 bits (8B) from the memory
channels.
Virtual Single Channel (VSC)
If both channels are populated with different memory configurations,
the MCH defaults to Virtual Single Channel.
Dual Channel (DC)
Dual channel provides better system performance because it doubles
the data transfer rate.
Dynamic Mode Addressing
This mode minimizes the overhead of opening/closing pages in
memory banks allowing for row switching to be done less often.
