In order to take advantage of the dual-channel bandwidth capability, both
memory sockets must be populated and must match in size.
NOTE:
The available memory displayed does not reflect the complete maximum
memory installed because some memory is reserved for system files.
NOTE:
To enable Intel® Active Management Technology (iAMT), you must have a
DIMM in the memory connector labeled A. For more information about the memory
connector see your computer's Service Manual at support.dell.com. For more
