Server-Specific DDR5 Kit

This 32 GB kit contains two 16 GB DDR5 4800 CL40 registered ECC RDIMMs built for HP ProLiant Gen11 servers. It targets administrators who need to expand memory capacity in DL385, DL560, DX360, DX365 or ML350 platforms without mixing memory types.

Replaces Lower-Capacity DIMMs

The upgrade is worthwhile when existing 8 GB or 16 GB modules leave headroom unused and workloads demand more simultaneous threads. It will not fit standard desktops or workstations that require unbuffered or load-reduced memory.

Sustained Load Behaviour

Registered buffering and on-die ECC keep data integrity intact during continuous multi-socket operation at 1.1 V. The modules run at JEDEC-standard 4800 MT/s without overclocking, delivering stable throughput for virtualisation and database tasks.

Questions about this item

Does this 288-pin DDR5 RDIMM fit the memory slots in an HP ProLiant DL385 Gen11?

Yes, the 288-pin DDR5 4800 CL40 1.1 V registered ECC modules are listed as compatible with the DL385 Gen11 and the other Gen11 ProLiant models.

What is the correct way to install the two 16 GB modules, and what mistake should I avoid?

Install both modules in matched channel slots according to the server's population guide; do not mix these registered DIMMs with unbuffered or load-reduced memory.

Will the ECC registered DIMMs need any firmware updates or battery replacements during their service life?

No firmware or battery maintenance is required; the modules are JEDEC-standard DDR5 ECC registered DIMMs designed for the server's lifetime.
