Single-module capacity

This OWC module provides 64GB of DDR5 ECC Registered memory in a single 288-pin RDIMM. It is built for HP Alletra 4110 and 4120 storage servers that require registered, error-correcting DIMMs. Standard desktop or unbuffered workstation boards will not accept this module. Buyers needing non-ECC or load-reduced memory cannot use this part.

Registered ECC with 2Rx4 organisation

The decisive specification is the registered ECC design with a 2Rx4 rank layout running at DDR5 5600 (PC5-44800) with CL46 latency at 1.1V. This combination ensures signal integrity and error correction for the Alletra 4110 and 4120 memory controllers. Mixing with unbuffered or load-reduced DIMMs is not supported.

Slot population for Alletra 4110 and 4120

Each module occupies one 288-pin DDR5 RDIMM slot in the server chassis. Adding this 64GB DIMM increases total capacity without requiring a matched pair, freeing remaining slots for further expansion. The module operates at the standard 1.1V DDR5 voltage, so no special power provisioning is needed beyond the server's existing memory subsystem.
