NEMIX RAM
A 32 GB DDR4 2666 ECC LRDIMM module built for HPE ProLiant DL360 G9 servers
This 32GB DDR4 LRDIMM is built for HPE ProLiant DL360 G9 servers that require ECC load-reduced memory. It suits administrators expanding capacity in virtualisation hosts or database nodes where registered modules are mandatory. The single-module kit allows precise population of empty slots without buying unneeded pairs. Buyers needing non-ECC desktop memory or standard RDIMM modules for other platforms cannot use this part.
Installation follows the server's documented DIMM sequence; the module keys into the 288-pin slot and locks with the ejector levers in seconds. No heat spreader means the board sits flush in dense configurations. Errors usually appear when mixing LRDIMM with RDIMM in the same channel or when the BIOS is not updated to recognise 2Rx4 density. Always verify the population rules in the HPE service guide before powering on.
One module delivers 32GB at DDR4 2666 PC4-21300 with CL19 latency at 1.2V. Sixteen such modules reach the 1TB system maximum supported by the platform. The load-reduced design reduces electrical load on the memory bus, allowing full population without down-clocking. Workloads exceeding 1TB per node or requiring faster than 2666 MT/s will outgrow this configuration.

Enter the HPE ProLiant DL360 G9 BIOS or iLO interface and confirm the memory speed shows 2666 MT/s, CAS latency 19, voltage 1.20 V and ECC status enabled for the installed module.
The box contains one 32 GB 288-pin DDR4 ECC LRDIMM (2Rx4, 1.20 V, CL19). No extra cables, brackets or heat spreaders are needed; the module installs directly into a free DIMM slot on the server board.
The listed part is a single 32 GB stick (1X32GB). Select this module when adding capacity one slot at a time; choose 64 GB modules only if your configuration specifically requires higher per-slot density.
