NOTE:
Minimum one memory kit per processor must be installed.
It is recommended to install memory kits in multiples of two (four identical DIMMs) for quad-channel
symmetric memory configurations to increase memory transfer speed.
When two processors are installed, balance the DIMMs across the two processors.
Mix configurations of RDIMM and LRDIMM are not supported.

N8102-623
NOTE:
Minimum one memory kit per processor must be installed.
The configured memories must be identical.
When two processors are installed, balance the DIMMs across the two processors.
The logical memory capacity at the time of memory sparing becomes two-thirds of physical capacity
with configurations less than 8GB DIMM and five-sixth physical capacity with configurations more
than 16GB DIMM.
The maximum memory speed is 1600 MHz.
