NOTE:

Minimum one memory kit per processor must be installed.

It is recommended to install memory kits in multiples of four (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.

At least 5 GB of memory is required for VMware ESXi.
