OWC 32GB DDR5 4800 ECC RDIMM

This 32GB DDR5 4800 CL40 2Rx8 288-pin 1.1V ECC Registered DIMM is built for HP ProLiant Gen11 servers including DL385, DL560, DX360, DX365 and ML350. It replaces HP part numbers P43328-B21, P46968-H21, P50311-B21, P58356-H21 and P62603-B21. The module is not compatible with standard desktop computers or unbuffered and load-reduced memory types.

Registered ECC for Gen11 ProLiant servers

The registered ECC design with 2Rx8 organisation is the single specification that determines fit. Only systems that require DDR5 4800 PC5-38400 registered ECC DIMMs will accept this module. Mixing with unbuffered or load-reduced DIMMs is not supported.

Sustained server workloads

Under continuous load the module maintains JEDEC DDR5 4800 speeds at 1.1V with CL40 latency. Error correction and registered buffering keep data integrity stable during extended operations in workstations, NAS systems, servers and network switches.

Perguntas sobre este artigo

What does the 4800 MT/s speed mean once the module is installed in a compatible HP ProLiant server?

The module runs at the JEDEC-standard 4800 MT/s data rate with CL40 latency at 1.1 V, delivering the rated PC5-38400 bandwidth when the server memory controller is configured for DDR5-4800 operation.

How does the DDR5 ECC registered interface affect what the module can do in practice?

The registered ECC design adds a register between the DRAM and the memory controller, enabling stable operation in multi-DIMM server configurations and providing single-bit error correction and multi-bit detection for data integrity.

What physical slot and clearance does the 288-pin RDIMM need to fit in the listed ProLiant models?

It requires a standard 288-pin DDR5 DIMM socket; the module has no heat spreader, so it fits within the normal DIMM height envelope of the DL385 Gen11, DL560 Gen11, DX360 Gen11, DX365 Gen11 and ML350 Gen11 chassis.
