DIMM Locations

DIMM addresses, and consequently their NAC names, are based on their location on the
processor module motherboard, as well as the slot in which the processor is installed. For
example, the full address for the DIMM that is installed in the front-left corner of the processor
module that is installed in slot 0 is:
/System/Memory/DIMMs/DIMM_0.
or
/SYS/PM0/CM1/CMP/BOB0/CH0/D0.
