Server Memory Kit

This OWC kit provides 512 GB of DDR4 ECC LRDIMM capacity across four 128 GB modules for the HP SimpliVity 380 Gen10. It targets administrators who need to maximise memory density in that specific server platform. The load-reduced design is required by the system and cannot be mixed with registered or unbuffered DIMMs. Buyers using standard desktop or consumer workstation boards cannot use this memory.

Sustained Operation

Each module runs at 3200 MT/s with CL22 latency at 1.2 V, and the kit is backward compatible with 2133, 2400, 2666 and 2933 MT/s bus speeds. ECC load-reduced architecture reduces electrical load on the memory controller during continuous workloads. The modules carry no heat spreader, so chassis airflow must handle thermal dissipation during extended duty cycles.

Build and Installation

The 288-pin LRDIMM form factor fits only slots wired for DDR4 load-reduced memory in the supported server. Four modules populate four DIMM slots to reach the full 512 GB kit capacity. OWC validates every module in-house and the kit replaces HP part numbers including P06037-B21, P07652-B21 and P25206-B21.

Questions about this item

How much power does the 1.2V DDR4 3200 LRDIMM kit draw when the server runs continuously?

Each module operates at 1.2V. Total power depends on the HP SimpliVity 380 Gen10 memory-controller load; the kit itself adds no separate power connector.

What must the HP SimpliVity 380 Gen10 already have to accept this 4Rx4 ECC LRDIMM kit?

The server must support DDR4 288-pin Load-Reduced ECC memory and have four free DIMM slots; mixing with unbuffered or registered DIMMs is not supported.

Will these 3200MHz CL22 modules down-clock to work beside existing 2666MHz DDR4 in the same chassis?

Yes — the kit is backward-compatible with 2133, 2400, 2666 and 2933MHz speeds, so it will run at the lowest common speed populated.
