128GB DDR5 4800 ECC RDIMM

This 128GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1V operation. It is a 288-pin ECC Registered DIMM built for Dell PowerEdge R760xa, R860 and R960 servers. The 4Rx4 organisation suits high-density memory configurations in enterprise workloads.

Sustained enterprise workloads

ECC and registered buffering protect data integrity during continuous operation in virtualisation, database or compute clusters. The JEDEC-standard 4800 speed delivers predictable throughput without overclocking headroom. This module cannot be mixed with unbuffered or load-reduced memory types.

Single-module 128GB upgrade

The RDIMM arrives without a heat spreader, relying on server chassis airflow for thermal management. It replaces Dell part AC449974 and SNPMMWR9C/128G directly. Buyers needing consumer desktop memory or non-ECC modules should look elsewhere.

Perguntas sobre este artigo

How much power does the 1.1V DDR5 4800 module draw when the server runs continuously?

The module operates at 1.1V, which is the standard DDR5 voltage, keeping power draw low during sustained workloads in PowerEdge R760xa, R860 or R960 systems.

Does this 288-pin ECC Registered RDIMM require a specific Dell PowerEdge server to function?

It is validated for PowerEdge R760xa, R860 and R960; the motherboard must support DDR5 4800 ECC Registered memory in a 288-pin slot.

Can I add this 4Rx4 CL40 stick alongside existing DDR5 RDIMMs in my R860?

Yes, provided the other modules are also DDR5 4800 ECC Registered; mixing with unbuffered or load-reduced DIMMs is not supported.
