  • Validated for Dell PowerEdge XE9680 ensures drop-in compatibility

Single-module server upgrade

This OWC DDR5 module provides 128GB of ECC registered memory in a single 288-pin RDIMM. It operates at 4800MHz with CL40 latency and 1.1V voltage. The 4Rx4 rank configuration is designed for the Dell PowerEdge XE9680 server platform.

ECC registered reliability

Error-correcting code detects and corrects single-bit errors to maintain data integrity under continuous workloads. Registered buffering reduces electrical load on the memory controller for stable operation at high capacity. The module replaces Dell part numbers AC449974 and SNPMMWR9C/128G.

Workstation and server builders only

Suitable for administrators expanding memory in a compatible Dell PowerEdge XE9680 or similar workstation, NAS, or server that requires DDR5 ECC registered RDIMMs. Not for desktop PCs, laptops, or consumer motherboards that accept only unbuffered non-ECC memory. Cannot be mixed with load-reduced or unbuffered modules in the same system.

Perguntas sobre este artigo

What replacement does the 128GB DDR5 4800 ECC RDIMM need when it reaches end of life?

The module is built to JEDEC and RoHS standards and covered by a limited lifetime warranty with an advanced replacement programme.

What limit appears first on the 4Rx4 1.1V registered DIMM during sustained workloads?

The registered buffer and ECC logic add one cycle of latency, so memory-controller bandwidth saturation typically arrives before thermal throttling.

How much noise and heat does the 288-pin 128GB module produce when the XE9680 runs continuously?

With no heat spreader and a 1.1V operating voltage, the stick relies on chassis airflow; it adds no fan noise and minimal thermal load.
