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 TSV RDIMM are not supported.

When N8102-667F is installed, the operable ambient temperature is up to 35 degrees Celsius.

When N8102-667F is installed, N8118-300 2.5-inch PCIeSSD Installation Kit is not supported.
