A 32 GB DDR4 2666 MHz ECC LRDIMM module for HPE ProLiant ML350 G10 servers
This 32GB DDR4 2666MHz ECC LRDIMM module is designed for the HPE ProLiant ML350 G10 server. It provides registered, load-reduced memory with error correction for stable operation in enterprise environments. The single-rank 2Rx4 configuration fits standard 288-pin DDR4 slots. IT professionals upgrading compatible HPE systems will find this module matches the required specifications.
Load-reduced DIMMs reduce electrical loading on the memory bus, allowing the server to maintain signal integrity when all slots are populated. ECC circuitry detects and corrects single-bit errors during continuous operation, preventing data corruption under heavy workloads. The 1.2V operating voltage keeps power draw consistent during extended compute tasks. CL19 latency delivers predictable timing for virtualisation and database workloads.
Confirm the ML350 G10 has an available 288-pin DDR4 slot and review the server's memory population guide for supported LRDIMM configurations. Mixing LRDIMMs with standard RDIMMs is not supported by the platform. Ensure the system BIOS is current to recognise the 32GB capacity per module. The module uses major OEM chips from Samsung, Micron or Hynix depending on supply.

Load-reduced design places less electrical load on the memory bus, which typically lowers power draw per module at the same 1.2V level.
The module is validated for HPE ProLiant ML350 G10 systems with 288-pin DDR4 slots.
Mixing LRDIMM and RDIMM types in the same ProLiant is not supported by HPE; all slots must use the same registered or load-reduced technology.
