OWC 32GB DDR5 4800 ECC RDIMM

This 32GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1V operation. It is built as a 2Rx8 registered ECC RDIMM for HP ProLiant DL320 Gen11, DL380a Gen11 and DX320 Gen11 servers. The part number is 4R8D52R832GB and it replaces HP part numbers P43328-B21, P46968-H21, P50311-B21, P58356-H21 and P62603-B21.

Server memory slot compatibility

The 288-pin DIMM fits registered ECC slots in the listed Gen11 ProLiant systems. It cannot be mixed with unbuffered or load-reduced ECC modules and will not work in standard desktop computers. Each module provides a single 32GB upgrade path for supported configurations.

Sustained ECC registered operation

Registered buffering and on-die ECC maintain data integrity during continuous server workloads. The 1.1V DDR5 design keeps power draw steady under load while the module meets JEDEC and RoHS compliance for reliable long-term deployment.

Questions sur cet article

What sustained-use limit appears first with this 2Rx8 registered ECC module?

The 2Rx8 organisation and 1.1 V DDR5 design keep per-module power low, so thermal throttling is unlikely; the practical limit is the server's maximum supported memory capacity.

How does the 1.1 V DDR5 4800 CL40 registered DIMM behave for heat and noise during all-day operation?

Running at the standard 1.1 V with no heat spreader, the module relies on the server's forced airflow; it adds minimal heat and no audible noise of its own.

Which HP ProLiant Gen11 servers must I already own for this 288-pin RDIMM to work?

This module is validated for HP ProLiant DL320 Gen11, DL380a Gen11 and DX320 Gen11 systems; it will not function in standard desktops or other platforms.
