OWC 16GB DDR5 4800 ECC RDIMM

This OWC module is a 16GB DDR5 4800 PC5-38400 CL40 ECC Registered DIMM built for HP ProLiant DL320 Gen11, DL380a Gen11 and DX320 Gen11 servers. It runs at 1.1V with a 1Rx8 layout on a 288-pin form factor and includes no heat spreader.

Suited for HP ProLiant Gen11 upgrades

IT teams maintaining the listed HP ProLiant Gen11 models can install this single 16GB stick to replace HP part numbers P43322-B21, P50309-B21, P58354-H21 or P62601-B21. Buyers who need unbuffered memory or load-reduced DIMMs for other platforms cannot use this registered ECC module.

Registered ECC decides compatibility

The registered ECC design is the single specification that determines whether this DIMM fits the target system; it will not work in standard desktops or in boards that require unbuffered or load-reduced memory.

Perguntas sobre este artigo

How much power does the 1.1V DDR5 4800 RDIMM draw under continuous server load?

The module runs at 1.1V with JEDEC-standard DDR5 power management; exact wattage depends on the HP ProLiant DL320 Gen11, DL380a Gen11 or DX320 Gen11 platform and workload.

Which HP ProLiant Gen11 servers must I already own for this 16GB 1Rx8 ECC registered DIMM to work?

It is validated for HP ProLiant DL320 Gen11, DL380a Gen11 and DX320 Gen11; it will not function in standard desktops or other server models.

Can I mix this CL40 registered ECC module with older unbuffered or load-reduced DIMMs in the same Gen11 chassis?

No — the manufacturer states it cannot be mixed with unbuffered or ECC load-reduced memory; all slots must use registered ECC RDIMMs.
