SuperMicro DDR5 4800 ECC RDIMM kit

This 128 GB kit contains four 32 GB DDR5 4800 registered DIMMs with ECC and CL40 latency. It is built for SuperMicro GPU SuperServer models such as the SYS-821GE-TNHR, SYS-821GV-TNR and SYS-421GE-TNRT. The modules operate at 1.1 V and use a 1Rx4 organisation on major OEM chips.

Sustained load behaviour

Registered buffering and on-die ECC keep data integrity intact during continuous server workloads. The 4800 MT/s rate and CL40 timing deliver steady throughput for virtualisation, GPU compute and database tasks without the errors that unbuffered memory can introduce.

Installation notes

Each 288-pin RDIMM slots into the server motherboard like standard DDR5 memory. The kit is validated for the listed SuperMicro systems, so mixing with different speeds, ranks or unbuffered modules is not supported. Always follow the system manual for correct population order.

Questions about this item

How much heat and power will the 1.1V DDR5 4800 modules generate when running continuously?

Each module operates at 1.10V standard DDR5 voltage. No heat spreaders are fitted, so airflow across the 288-pin RDIMM sticks is required for cooling.

What motherboard slots and CPU memory controller must my SuperMicro server provide for this kit to function?

The server needs four DDR5 RDIMM slots supporting 4800 MT/s registered ECC memory and a CPU memory controller that accepts 1Rx4 organisation.

Can I mix these 32GB 1Rx4 CL40 RDIMMs with different-capacity DDR5 registered ECC modules already installed?

Mixing ranks or capacities is not recommended; the kit is validated as a matched 4 x 32GB set for the listed SuperMicro SYS-821 and SYS-421 models.
