64GB DDR5 ECC RDIMM for Supermicro servers

This 64GB DDR5 4800 registered DIMM is built for Supermicro GPU SuperServer platforms including the SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT. It targets administrators who need ECC protection and registered signalling in a single high-density module.

Major OEM Samsung Micron Hynix chips tested under

Modules use major OEM DRAM from Samsung, Micron or Hynix and are rigorously stress tested before shipment. The registered buffer and on-die ECC reduce electrical load on the memory controller while correcting single-bit errors, improving stability in multi-DIMM configurations.

64GB capacity at 4800MT/s CL40 1.1V

The 64GB density suits memory-hungry virtualisation, GPU compute and large-database workloads on supported Supermicro systems. Headroom ends when the platform’s maximum DIMM count or total memory limit is reached, or when workloads demand speeds beyond 4800MT/s.

Questions sur cet article

Will the 2Rx4 DDR5 ECC RDIMM need a heat spreader added later?

The module ships without a heat spreader; most server chassis provide enough airflow for 1.1 V DDR5 4800 operation, but verify your SuperMicro GPU SuperServer airflow before deciding.

What limits sustained throughput on the CL40 4800 MT/s registered DIMM?

The registered buffer and CL40 latency set the ceiling; the 2Rx4 organisation and 1.1 V supply keep bandwidth at PC5-38400 without further bottlenecks.

How much heat and power does the 64 GB 1.1 V DDR5 RDIMM produce under all-day load?

At 1.10 V the module draws minimal power for 64 GB, and the lack of a spreader means heat stays low provided the SuperMicro server fans maintain normal flow.
