OWC 256GB (2x128GB) DDR4 3200 CL22 ECC LRDIMM HP SimpliVity 380 Gen10

HP SimpliVity 380 Gen10 memory kit

This 256 GB kit supplies two 128 GB DDR4 3200 CL22 ECC load-reduced DIMMs built for the HP SimpliVity 380 Gen10 server. The modules operate at 1.2 V and use a 288-pin 4Rx4 layout that matches the platform’s registered memory architecture. The kit targets administrators who need to expand capacity on this specific hyper-converged node without mixing memory types.

ECC load-reduced behaviour

Load-reduced ECC buffers the data bus so the memory controller sees a single electrical load per rank, allowing higher densities than standard registered DIMMs. The modules cannot be mixed with unbuffered or registered ECC memory, so the full population must use identical LRDIMM parts. Backward compatibility with 2133, 2400, 2666 and 2933 MHz speeds lets the kit drop into slower bus configurations if the firmware requires it.

288-pin LRDIMM form factor

Each stick follows the JEDEC 288-pin DDR4 LRDIMM outline and has no heat spreader, relying on server chassis airflow for cooling. The 4Rx4 organisation means four logical ranks per module, which the SimpliVity 380 Gen10 memory controller must support in its qualified population rules. Installers should verify the server’s maximum DIMM-per-channel limit and rank-count ceiling before adding this kit to an existing configuration.
