SK hynix HMCG78MEBRA 16GB DDR5-4800 ECC RDIMM Server Memory

Overview

HMCG78MEBRA is a SK hynix 16GB DDR5 ECC Registered DIMM (RDIMM) rated at 4800 MT/s. It is intended for server and workstation platforms that explicitly support DDR5 registered memory.

Product Positioning

This module is best treated as an exact server-memory part rather than a generic DDR5 RAM replacement. It is particularly relevant for entry and maintenance-oriented DDR5 server configurations where a 16GB registered module is specifically qualified. In production servers, matching the required DIMM type, capacity, speed, rank organization and platform population rules is more important than choosing memory by capacity alone.

Basic Technical Information

Typical Application Areas

• Enterprise and data-center servers
• Virtualization and private-cloud hosts
• Database, storage and networking systems
• Professional workstations that support DDR5 RDIMM
• Server repair, expansion and qualified spare-parts sourcing

Selection Notes

DDR5 RDIMM is not interchangeable with DDR5 UDIMM or SO-DIMM. Before ordering HMCG78MEBRA, verify that the server or workstation supports DDR5 registered ECC memory and check the system vendor's supported capacity, speed, rank and DIMM population rules. When replacing an installed module, matching the original manufacturer part number is the safest starting point.

Related Sourcing Options

For projects where the exact part number is unavailable, SMC can check same-generation DDR5 RDIMM options from Samsung, SK hynix and Micron. Any alternative should be evaluated against the target server platform rather than assumed compatible from capacity and speed alone.
