OWC 32GB (2x16GB) DDR5 4800 CL40 ECC RDIMM Kit for HP ProLiant Gen11

SKU CH-PMFG-A3CTZ

A 32 GB DDR5 ECC registered DIMM kit running at 4800 MHz CL40 for HP ProLiant Gen11 servers

  • Capacity32GB (2 x 16GB)
  • Type288-Pin DDR5 ECC RDIMM
  • SpeedDDR5 4800 (PC5 38400)
  • CAS LatencyCL40
  • Voltage1.1V
  • ECCYes

Capacity 32GB (2 x 16GB)

  • ECC registered design protects data integrity in critical workloads
  • 32 GB dual-channel kit expands server memory capacity
  • DDR5 4800 speed with CL40 latency accelerates throughput
  • 1 V low-voltage operation reduces power draw per module
  • Validated for HP ProLiant DL320 Gen11, DL380a Gen11 and DX320 Gen11

Target Server Memory Upgrade

This 32GB kit contains two 16GB DDR5 4800 ECC Registered DIMMs built for HP ProLiant DL320 Gen11, DL380a Gen11 and DX320 Gen11 servers. It runs at 1.1V with CL40 latency and a 1Rx8 organisation, delivering error-correcting registered memory for workloads that require data integrity.

Replacing Unbuffered or Mixed Modules

The kit replaces non-ECC unbuffered DIMMs or mismatched registered sets that cannot operate in these Gen11 platforms. The jump is worth it when the system demands JEDEC-standard registered ECC memory and the existing slots are populated with incompatible module types.

Sustained Load Behaviour

Under continuous operation the registered buffer reduces electrical loading on the memory controller, allowing stable throughput at the rated 4800 MT/s without the signal degradation seen in unbuffered configurations. The absence of a heat spreader means airflow across the 288-pin modules must be maintained by the server chassis cooling design.

Questions sur cet article

Will these 288-pin DDR5 RDIMMs fit the DIMM slots on an HP ProLiant DL380a Gen11?

Yes, the kit is a 288-pin DDR5 ECC registered DIMM designed for HP ProLiant DL320 Gen11, DL380a Gen11 and DX320 Gen11 servers.

What is the correct way to install the two 16 GB modules, and which step do people often miss?

Power down the server, open the chassis, align each module's notch with the slot key, press firmly until both retention clips click, then verify in BIOS that both 16 GB modules are detected at 4800 MT/s.

When will the ECC registered memory need replacement or maintenance?

DDR5 ECC registered modules have no scheduled maintenance; replace only if system logs report uncorrectable errors or if a capacity upgrade is required later.
