Channel B will be divided into two parts. One part of channel B is used together with channel A and mapped
to dual channel operation. The second part of channel B is mapped to single channel operation.
Note:
Regardless of the memory configuration Dual Channel, Single Channel or Flex, the DIMMA1 must always
be populated. This is a requirement of the Intel® Management Engine.
The below tables shows examples of possible Memory slot configurations for the support of the various
Memory modes.
