What this module provides

This is a 16GB DDR5 4800 ECC registered DIMM built as a compatible replacement for specific Hynix server modules. It targets administrators upgrading or repairing workstation and server platforms that require registered memory with error correction.

Compatibility checks before ordering

Verify that your motherboard accepts DDR5 registered DIMMs and supports ECC operation at 1.1V. Confirm the platform can use a 1Rx8 organisation and that the 288-pin form factor matches the memory slots in your chassis.

Build quality and daily implications

The module uses major-brand chips and undergoes quality-assurance testing for dependable server-grade reliability. The registered design adds a buffer that reduces electrical load on the memory controller, while the ECC function corrects single-bit errors to protect data integrity in continuous workloads.

Perguntas sobre este artigo

What comes in the box and do I need to buy anything else to install this module?

The package includes a single 16 GB DDR5 4800 ECC RDIMM. No extra components or cables are required; the module plugs directly into a compatible 288-pin DDR5 server DIMM slot.

How do I choose between the listed Hynix part numbers HMCG78MEBRA103N, 107N, 110N and 113N?

All five Hynix part numbers are covered by this A-Tech replacement module. Select the one that matches the label on your existing stick or your system’s qualified-vendor list; the electrical specs are identical.

What does the 4800 MT/s rating mean once the DIMM is installed in a server?

The module runs at 4800 MT/s with CL40 latency at the standard 1.10 V DDR5 voltage, providing the rated PC5-38400 bandwidth when the platform’s memory controller is set to that speed.
