  • 1 V standard voltage reduces power draw per module

Capacity and fit

This 96GB DDR5 module uses the 288-pin RDIMM form factor and operates at 5600MHz with a CAS latency of 40. It is built for servers and workstations that require registered ECC memory to maintain data integrity under sustained workloads. The 2Rx4 organisation and 1.10V voltage match the DDR5 standard for high-density registered DIMMs.

Direct replacement targets

The module is a compatible replacement for Hynix part numbers HMCGM4MGBRB, HMCGM4MGBRB244N, HMCGM4MGBRB245N and HMCGM4MGBRB248N. The upgrade is worth it when a system board lists one of those exact part numbers or when the platform demands a single 96GB registered ECC DIMM at the PC5-44800 speed grade. It is not for systems that accept only unbuffered UDIMMs or that are limited to lower-density modules.

DDR5 registered DIMM constraints

DDR5 RDIMMs require a motherboard with a registered memory controller and cannot be used in consumer platforms that support only unbuffered memory. The 5600MHz data rate will down-clock automatically if the CPU or chipset specifies a lower maximum speed. Mixing ranks or capacities across channels may prevent the system from reaching the rated frequency.

Questions about this item

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

Yes, the 288-pin DDR5 RDIMM form factor matches standard DDR5 registered DIMM slots in compatible servers and workstations.

What is the correct seating procedure for this 96GB ECC RDIMM?

Align the module notch with the slot key, press firmly until both retention clips click, and follow your system manual for channel population order.

Will the 2Rx4 rank organisation require a firmware update later?

The 2Rx4 configuration is a hardware characteristic; any required firmware updates depend on your server vendor's memory qualification list.
