NEMIX RAM
32 GB DDR4 2666 ECC load-reduced DIMM, CL19 1.2 V, validated for HPE ProLiant DL380 G9 servers
This 32GB DDR4 2666 ECC LRDIMM module is built for the HPE ProLiant DL380 G9 server. It targets IT teams who need to expand memory capacity in that specific platform while maintaining error correction and load-reduced signalling. The single 32GB stick uses a 2Rx4 organisation and runs at 1.2V.
Replacing lower-capacity LRDIMMs with this 32GB module increases total memory without adding slots, which is valuable when all 24 DIMM sockets are occupied. The jump is worth it when workloads such as virtualisation or large databases demand more addressable memory per channel and the server firmware supports 32GB LRDIMM density.
Confirm the DL380 G9 has free 288-pin DDR4 slots and that the system BIOS is current enough to recognise 32GB 2Rx4 LRDIMMs. Check the server maintenance guide for maximum supported capacity per socket and any population rules that apply to load-reduced modules.

Yes, the 288-pin DDR4 LRDIMM form factor matches the DL380 G9 DIMM sockets exactly.
Install modules in the sequence shown in the server maintenance guide, filling the lowest-numbered slots for each processor first.
The DRAM chips themselves need no firmware; only the server system BIOS may require updates for memory compatibility.
