OWC 256GB (2x128GB) DDR4 3200 CL22 4Rx4 LRDIMM memory upgrade

Server-grade memory kit

This OWC kit provides 256 GB of DDR4 3200 ECC load-reduced memory in two 128 GB modules. It is built for HP ProLiant DL385 Gen10 Plus, DL385 Gen10 Plus v2, DX360 Gen10 Plus and DX385 Gen10 Plus servers. The modules operate at 1.2 V with CL22 latency and a 4Rx4 organisation. They are intended for workloads that require large capacity and error correction.

288-pin LRDIMM form factor

Each module uses the 288-pin LRDIMM form factor without a heat spreader, fitting the standard server DIMM slots on the listed platforms. Load-reduced buffering reduces electrical load on the memory controller, allowing higher densities per channel. The kit cannot be mixed with unbuffered or standard registered ECC DIMMs, so all populated slots must use the same memory type.

Verify platform and population rules

Confirm that your server model matches the supported ProLiant list and check the maximum DIMM count per processor. Ensure the BIOS is current enough to recognise 128 GB LRDIMMs at 3200 MT/s, and plan to populate identical modules in matched channels. Buyers who need unbuffered or standard registered ECC memory should choose a different product.
