Server-grade DDR5 ECC RDIMM

This 16 GB DDR5 4800 CL40 module is a registered ECC DIMM built for the Dell PowerEdge R760xd2. It operates at 1.1 V with a 1Rx8 organisation and a 288-pin interface. The part replaces Dell AC239377 and SNP1V1N1C/16G in compatible servers and workstations.

Verify registered ECC requirement

Confirm the target system accepts registered ECC DDR5 memory before ordering. This module will not work in platforms that require unbuffered or load-reduced DIMMs. Mixing registered with unbuffered or load-reduced memory is not supported and will prevent the system from posting.

Single-module capacity upgrade

Install one 16 GB stick to add capacity to an available slot in the R760xd2. The registered buffer reduces electrical load on the memory controller, allowing larger total memory configurations. No heat spreader is fitted, so ensure chassis airflow meets the server’s thermal design.
