64 GB DDR5 ECC RDIMM kit for Supermicro servers

This 64 GB kit contains two 32 GB DDR5 4800 registered DIMMs built with ECC and a 1Rx4 organisation. It is designed for Supermicro Hyper SuperServer models SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R. The modules operate at 1.1 V and carry a CL40 latency rating.

Sustained-load behaviour with ECC registered design

Registered buffering reduces electrical load on the memory controller, allowing stable operation across all populated slots during continuous server workloads. On-die ECC corrects single-bit errors in real time, preventing data corruption during long compute runs. The 1.1 V operating voltage limits heat rise inside dense chassis configurations.

Straightforward 288-pin installation

Each module keys into a standard 288-pin DDR5 RDIMM socket without tools or heat-spreader clearance issues. The main installation risk is populating slots in the wrong sequence for the specific Supermicro motherboard, which can prevent the system from posting or disable ECC functionality. Consult the server manual for the correct population order before seating the DIMMs.

Preguntas sobre este artículo

How much power does this 1.1 V DDR5 4800 kit draw when the server runs all day?

Each module operates at 1.1 V; total system power depends on the platform and workload, so consult the server documentation for exact figures.

What server platform is required for these 288-pin ECC RDIMMs to function?

The kit is validated for SuperMicro Hyper SuperServer SYS-121H-TNR, SYS-221H-TNR and SYS-221H-TN24R systems.

Can this 1Rx4 registered DDR5 kit share memory channels with existing DDR5 RDIMMs of different rank or speed?

Mixing ranks or speeds on the same channel is not recommended; populate identical modules per channel for stable operation.
