SK hynix HMCGM4MGBRB – 96GB DDR5-5600 ECC Registered Server Memory

Description

The SK hynix HMCGM4MGBRB provides 96GB of high-density DDR5 server memory for modern enterprise platforms requiring substantial memory capacity without sacrificing memory bandwidth. Operating at 5600MT/s, the module offers a theoretical peak transfer bandwidth of approximately 44.8GB/s per DIMM.

The module uses a 2Rx4 dual-rank architecture with x4 organization and is built as an ECC Registered DIMM (RDIMM). Registered memory is designed for server-class memory controllers and helps maintain signal integrity in systems populated with multiple DIMMs.

ECC functionality provides memory-error detection and correction capabilities, making the module appropriate for environments where data integrity and system availability are important. The 96GB capacity is particularly useful for virtualization hosts, large databases, cloud infrastructure, analytics, and other applications with high memory requirements.

The exact HMCGM4MGBRB part number is documented as an SK hynix 96GB DDR5-5600 RDIMM, with 2Rx4 organization, PC5-44800R speed classification, CL46 timing, and 1.1V voltage.

3. Complete Technical Specification

The 96GB, DDR5-5600, 2Rx4, 1.1V and 288-pin characteristics are independently documented, while Memory.NET specifies PC5-44800R, CL46, tRCD 45 and tRP 45.

4. Applications

The HMCGM4MGBRB is suitable for:

• Enterprise server memory expansion
• Data-center infrastructure
• Virtualization hosts
• Cloud-computing platforms
• Large-scale database servers
• In-memory databases
• Web and application servers
• High-performance computing
• AI and machine-learning infrastructure where platform-qualified
• Data analytics
• Storage and file servers
• Engineering and scientific workloads
• High-memory professional workstations
• Enterprise server consolidation

The high 96GB-per-DIMM capacity makes it particularly useful where maximum memory density per channel is important.

5. Compatibility

The module is designed for server and professional platforms that explicitly support DDR5 ECC Registered DIMMs (RDIMM).

The exact HMCGM4MGBRB is listed as compatible memory for platforms including the Gigabyte MS73-HB2, where it is identified as a 96GB SK hynix DDR5-5600 RDIMM.

It is also documented as a server-memory solution for platforms from major enterprise OEM families, subject to the specific CPU, motherboard, BIOS, DIMM population rules, and supported memory density.

Compatibility Requirements

The host platform should support:

• DDR5 ECC RDIMM
• 5600MT/s DDR5 memory
• 96GB DIMM capacity
• 2Rx4 memory organization, where required
• 288-pin registered DIMMs
• The specific DIMM density and rank configuration

Important: DDR5 RDIMM is not interchangeable with DDR5 UDIMM or SO-DIMM. The server motherboard and processor memory controller must explicitly support ECC Registered DDR5 memory.

When installing multiple modules, follow the server manufacturer’s DIMM population guidelines. Depending on the platform and number of populated channels, the system may automatically operate the memory below its maximum rated 5600MT/s speed.
