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 five-sixth of physical capacity.

The maximum memory speed is 1866 MHz.

Maximum Memory Speed
See the table below for the actual maximum memory transfer speed in Independent Channel / Memory Sparing Configuration.
DDR4 memory speed depends on the type of DIMMs, the native memory bus speed of the memory controller and memory
configuration. All memory buses operate at the clock frequency of the DIMM with the lowest frequency.
The maximum memory transfer rate is 1866 MHz with Memory Sparing Configuration.
