Server memory upgrade kit

This OWC kit supplies 1TB of DDR4 ECC LRDIMM memory across eight 128GB modules. Each module runs at 3200MHz with CL22 latency at 1.2V. The load-reduced design targets the HP SimpliVity 380 Gen10 platform for virtualisation and database workloads.

Replaces multiple HP part numbers

The kit replaces HP part numbers P06037-B21 P06037-H21 P06037-K21 P43171-B21 P07652-B21 P07652-H21 P25206-B21. Backward compatibility covers 2133MHz, 2400MHz, 2666MHz and 2933MHz systems. The jump is worth it when consolidating smaller DIMMs to reach higher capacity per channel.

Sustained load behaviour

Load-reduced buffering reduces electrical load on the memory bus during continuous operation. ECC corrects single-bit errors in real time to maintain data integrity under heavy throughput. Modules operate at standard 1.2V without a heat spreader, relying on server chassis airflow for thermal management.

Questions about this item

Will these 288-pin LRDIMMs fit the HP SimpliVity 380 Gen10 memory slots?

Yes. The kit is built for the HP SimpliVity 380 Gen10 and uses the standard 288-pin DDR4 LRDIMM form factor that the server expects.

What is the correct installation sequence for the eight 128GB modules?

Populate all eight slots identically; the common mistake is mixing these 4Rx4 load-reduced DIMMs with registered or unbuffered memory, which the platform does not support.

When should I expect to replace a module in this 1TB kit?

Modules are covered by a limited lifetime warranty with advanced replacement; swap a stick only if diagnostics report a correctable or uncorrectable ECC error on that specific DIMM.
