32 GB DDR4 2666 ECC LRDIMM module boosts HPE ProLiant DL385 G10 server capacity
This 32GB DDR4 2666 ECC LRDIMM module is built for HPE ProLiant DL385 G10 servers. It delivers 32GB of registered, load-reduced memory with error correction for stable operation in multi-socket enterprise workloads. The single-rank 2Rx4 organisation and 1.2V voltage match the platform's native memory specification. IT teams upgrading DL385 G10 nodes use this part to expand capacity without changing memory speed or topology.
The package contains one 32GB 288-pin LRDIMM tested at CL19 latency under load. No heat spreader is fitted, so airflow in dense server chassis remains unobstructed. Major OEM DRAM from Samsung, Micron or Hynix is used on each PCB. The module arrives in anti-static packing ready for immediate installation in an available DIMM slot.
Before ordering, confirm the DL385 G10 has a free DDR4 LRDIMM slot and that the planned configuration follows HPE's memory population guidelines for load-reduced modules. Mixed rank or voltage DIMMs in the same channel can prevent boot or reduce performance. Check the server's current memory layout against the maintenance manual to ensure the new 32GB module will be recognised at full 2666 MT/s speed.

No firmware updates or re-seating are required; the module is validated for the HPE ProLiant DL385 G10 and runs at its rated 1.2 V without further maintenance.
The CAS latency of CL19 sets the timing boundary; sustained throughput stays within the PC4-21300 rating without hitting a lower bottleneck.
The 1.2 V LRDIMM design keeps power draw low, so the server’s existing cooling handles the thermal load without audible fan-speed increases.
