OWC 32GB DDR5 4800 ECC RDIMM

This 32GB DDR5 4800 CL40 module is a registered ECC RDIMM built for servers and workstations. It runs at 1.1V with a 1Rx4 layout on a 288-pin interface and is designed as a direct replacement for specific Hynix part numbers. The module carries JEDEC and RoHS compliance for warranty-safe upgrades.

Replaces Hynix DDR5 4800 RDIMMs

It replaces Hynix modules HMCG84MEBQA107N, HMCG84MEBQA113N, HMCG84MEBQA115N, HMCG84MEBQA174N and HMCG84MEBRA107N. The jump is worth it when extending the life of existing DDR5 infrastructure or building new systems that require registered ECC memory at this speed and capacity. Mixing with unbuffered or load-reduced ECC is not supported.

Suits servers needing registered ECC

This module suits administrators upgrading compatible DDR5 servers or workstations that require registered ECC RDIMMs at 4800 MT/s. It is not for standard desktop computers, consumer laptops, or any system that only accepts unbuffered or load-reduced ECC memory. Buyers needing different capacities, speeds or form factors should look at other modules.

Perguntas sobre este artigo

Will the 288-pin DDR5 RDIMM fit my server's standard DDR5 DIMM slots?

Yes, the module uses the standard 288-pin DDR5 RDIMM form factor designed for server and workstation DDR5 slots.

What is the correct way to seat this registered ECC module, and what step do installers often miss?

Align the off-centre notch with the slot key, press firmly until both retention clips click shut, and verify the motherboard detects the full 32 GB capacity at DDR5 4800.

Does the lack of a heat spreader mean I need active airflow over the DIMMs for long-term reliability?

The module runs at 1.1 V JEDEC standard voltage; adequate chassis airflow is recommended, but no extra cooling is required beyond normal server ventilation.
