128GB DDR4 2666MHz ECC RDIMM

This registered DDR4 module delivers 128GB of error-correcting memory for servers and workstations that require data integrity under heavy workloads. It operates at 2666MHz with CL19 latency and 1.20V standard voltage. The 2S4Rx4 3DS/TSV organisation packs high density into a single 288-pin DIMM slot.

Registered DIMM for multi-slot scaling

Registered buffering reduces electrical load on the memory controller, allowing larger populations of modules per channel without signal degradation. ECC capability detects and corrects single-bit errors to maintain uptime in mission-critical applications. The module fits standard DDR4 RDIMM slots and requires a platform that supports registered ECC memory.

Sustained throughput at 1.20V

Continuous operation at 2666MHz is maintained within the 1.20V DDR4 specification, avoiding the voltage excursions that can throttle performance during extended compute tasks. The Micron chipset and 8Rx4 3DS stacking provide stable bandwidth for virtualisation, database and rendering workloads that saturate memory channels for hours. Thermal characteristics remain consistent because the registered design distributes current evenly across ranks.

Questions about this item

What sustained-use limit appears first with this 128GB DDR4 2666MHz ECC RDIMM running continuously?

The module operates at 1.20V with CL19 latency; under sustained load the registered buffer and 8Rx4 3DS/TSV organisation keep signal integrity within spec, so the first practical limit is the platform’s maximum supported capacity per channel rather than the DIMM itself.

How much noise, heat or power does this 288-pin registered DIMM produce when running all day?

As a passive component it generates no audible noise; power draw stays at the standard DDR4 1.2V level and heat output is proportional to the 2666MHz data rate, both well within normal server thermal envelopes.

What must the buyer already own for this Micron-compatible 128GB RDIMM to work?

A server or workstation motherboard with DDR4 RDIMM slots that supports 2666MHz ECC registered memory, 2S4Rx4 (8Rx4) rank configuration, and 3DS/TSV stacking for 128GB single-module capacity.
