Server memory kit

This OWC kit delivers 512GB of DDR4 3200 ECC registered memory across eight 64GB modules. It is built for HP ProLiant DL385 Gen10 Plus, DL385 Gen10 Plus v2, DX360 Gen10 Plus and DX385 Gen10 Plus servers that require registered DIMMs with 2Rx4 organisation. The modules run at 1.2V and carry a CL22 latency rating.

Replaces HP original parts

The kit substitutes HP part numbers P43170-B21, P06035-B21, P06035-H21, P07650-B21, P07650-H21, P07650-K21 and P25205-B21. The upgrade is worthwhile when the existing configuration cannot meet current workload demands or when expanding capacity avoids a full platform replacement. It cannot be mixed with unbuffered or load-reduced ECC memory.

Build integration

Each 288-pin RDIMM fits the supported ProLiant memory slots without a heat spreader, leaving airflow paths clear. The registered design places less electrical load on the memory controller, allowing all eight modules to operate together at the rated 3200 speed. Buyers needing unbuffered memory or consumer desktop compatibility should look elsewhere.

Perguntas sobre este artigo

Will the 288-pin DDR4 RDIMMs fit the memory slots in an HP ProLiant DL385 Gen10 Plus?

Yes — the kit uses 288-pin DDR4 registered DIMMs, which is the standard form factor for the DL385 Gen10 Plus and the other listed ProLiant models.

What is the correct population order for the eight 64 GB modules, and which step is most often missed?

Install all eight modules in matched sets per the server’s memory-installation guide; the step most often missed is updating the system BIOS before the first boot so the 2Rx4 ranks are recognised at 3200 MT/s.

When should the 512 GB kit be replaced or serviced?

ECC registered RDIMMs have no scheduled maintenance; replace a module only if the server’s memory diagnostics report correctable or uncorrectable errors on a specific DIMM.
