OWC 64GB DDR4 3200 ECC RDIMM

This OWC memory module delivers 64GB of DDR4 3200 capacity in a single 288-pin registered DIMM. It operates at CL22 latency and 1.2V with ECC error correction and a 2Rx4 rank configuration. The module is built specifically for the HP SimpliVity 380 Gen10 server platform.

Suited for HP SimpliVity 380 Gen10 expansion

This upgrade fits administrators adding memory to a compatible SimpliVity 380 Gen10 chassis. It will not work in standard desktop computers or consumer motherboards. Builders who need unbuffered memory, load-reduced DIMMs, or a different DDR generation should look elsewhere.

Straightforward server DIMM installation

The registered RDIMM seats in the standard 288-pin DDR4 slots of the target server. No heat spreader is present, so clearance is minimal. The main risk is mixing this registered ECC module with unbuffered or load-reduced memory, which the manufacturer advises against.

Questions about this item

What HP SimpliVity server model must I already own for this 64GB DDR4 3200 RDIMM to work?

This module is validated for the HP SimpliVity 380 Gen10; it replaces HP part numbers P43170-B21 P06035-B21 P06035-H21 P07650-B21 P07650-H21 P07650-K21 P25205-B21.

Can I keep my existing DDR4 3200 ECC registered modules and add this 2Rx4 stick alongside them?

OWC recommends that all DIMMs be the same capacity speed and manufacturer; mixing different ranks or vendors can prevent the server from posting.

How do I confirm the module is running at 3200 MT/s with ECC active after installation?

Check the server BIOS or iLO interface — it will report 3200 MT/s PC4-25600 CL22 1.2V and show ECC Registered status for the new DIMM.
