128GB DDR5 ECC RDIMM for Supermicro

This 128GB DDR5 4800 registered DIMM is built for Supermicro UP SuperServer SYS-111C-NR and SYS-521C-NR platforms. It targets IT professionals who need ECC integrity and registered signal buffering for mission-critical server workloads. The single-module design populates one 288-pin slot with a 4Rx4 organisation.

Sustained load behaviour with 4Rx4 organisation

The 4Rx4 rank layout spreads memory access across four ranks, helping the memory controller maintain throughput during extended compute tasks. ECC circuitry corrects single-bit errors on the fly, preventing data corruption during long-running jobs. Registered buffering reduces electrical load on the motherboard, supporting stability when all channels are populated.

Installation notes and common issues

The module installs in a standard 288-pin DDR5 slot and operates at 1.1V without a heat spreader. Compatibility is validated for the X13SEDW-F motherboard and the two SuperServer models listed; other boards may require a BIOS update or may not support 128GB single-rank density. Always consult the system manual for population rules and maximum capacity per channel.

Preguntas sobre este artículo

How much power does this 1.10V DDR5 4800 module draw when running continuously in a server?

The module operates at 1.10V DDR5 standard voltage; actual power draw depends on workload and the Supermicro platform's memory controller.

What motherboard and CPU combination must I already have for this 288-pin ECC RDIMM to function?

It requires a Supermicro motherboard such as the X13SEDW-F or a compatible UP SuperServer SYS-111C-NR or SYS-521C-NR with a CPU that supports DDR5 4800 registered ECC memory.

Can I mix this 4Rx4 128GB stick with smaller DDR5 ECC RDIMMs already installed in my Supermicro system?

Mixing ranks and capacities is platform-dependent; Supermicro's memory population rules for the X13SEDW-F and listed servers dictate which combinations are supported.
