Memory - NEC Express5800 System Configuration Manual

SYSTEM CONFIGURATION GUIDE

6 Memory

Available slots: 8 per processor
Category
Registered DIMM
(RDIMM)
Load Reduced
DIMM (LRDIMM)
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

At least 5 GB of memory is required for VMware ESXi5.5 and VMware ESXi 6.0.

N8102-625F does not support x4 SDDC.
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 1600 MHz with Memory Sparing Configuration.
