The system will operate in single channel mode if the SODIMM sockets are populated in one channel
only.
The system will operate in flex mode if the memory capacity of the SODIMM in Channel A is not equal to
the memory capacity of the SODIMM in Channel B. In flex mode, the channel populated with the least
amount of memory describes the total amount of memory assigned to dual channel and the remainder
is assigned to single channel. If one channel will have more memory than the other, the larger amount
should be assigned to channel A.
The system will operate in a higher-performing dual channel mode if the memory capacity of the
SODIMM in Channel A is equal to the memory capacity of the SODIMM in Channel B.
In any mode, the maximum operational speed is determined by the slowest SODIMM in the system.
