64GB DDR5 4800 ECC RDIMM for SuperMicro

This 64GB DDR5 4800 module is built for SuperMicro servers and workstations that require registered ECC memory. It runs at 1.10V with CL40 latency and a 2Rx4 organisation. The 288-pin RDIMM form factor fits the SYS-211E-FRN2T, SYS-211E-FRDN2T, X13SEM-F and X13SEM-TF platforms.

Sustained load stability

Registered buffering and on-die ECC keep data integrity intact during continuous workloads. The module is stress-tested under load before shipping, so it maintains the rated 4800 MT/s transfer rate without throttling. Samsung, Micron or Hynix DRAM chips provide consistent signal quality across all ranks.

Upgrade from smaller or slower DIMMs

Replacing lower-capacity DDR5 RDIMMs with this single 64GB stick adds density without consuming extra slots. The jump is worth it when the platform supports 2Rx4 registered modules and the workload benefits from ECC protection at 4800 MT/s.

Questions about this item

How much power does the 1.1 V DDR5 module draw when the server runs continuously?

The module operates at 1.1 V, the standard voltage for DDR5 registered DIMMs, so power draw stays within the platform’s DDR5 power budget.

What motherboard slot and chipset support are required to install this 288-pin RDIMM?

A SuperMicro motherboard with DDR5 RDIMM slots and a chipset that supports 4800 MT/s registered ECC memory is required.

Can this 2Rx4 registered DIMM be mixed with other DDR5 RDIMMs in the same SuperMicro platform?

Yes, it can be mixed with other DDR5 RDIMMs provided the platform supports mixed-rank populations at 4800 MT/s with ECC registered operation.
