Capacity 16GB

  • ECC registered design protects data integrity in Dell PowerEdge servers
  • 16 GB DDR5 module runs at 4800 MT/s with CL40 latency
  • Low 1.1 V operation reduces power draw in HS5610 and HS5620
  • Single-rank 1Rx8 layout simplifies memory population on 288-pin slots
  • Replaces Dell part numbers AC239377 SNP1V1N1C/16G for direct compatibility

Server memory upgrade

This 16GB DDR5 4800 CL40 1Rx8 288-pin 1.1V ECC Registered RDIMM is built for Dell PowerEdge HS5610 and HS5620 servers. It replaces Dell part numbers AC239377 and SNP1V1N1C/16G with a single module that meets JEDEC and RoHS standards.

Registered ECC design

The registered buffer and error-correcting code protect data integrity in multi-module configurations typical of workstation and server workloads. This module cannot be mixed with unbuffered or load-reduced memory and will not function in standard desktop platforms.

Single-module capacity

Each stick provides 16GB at DDR5 4800 speed; total system capacity depends on how many slots the HS5610 or HS5620 chassis populates. Buyers needing larger per-slot densities or different form factors must select other modules.

Questions about this item

Will the registered ECC design require any periodic firmware updates or module replacement over time?

No, the registered ECC RDIMM has no firmware and no moving parts, so it does not need scheduled updates or preventive replacement.

What is the first limit reached when the module runs continuously at DDR5 4800 CL40?

The CAS latency of CL40 at 4800 MT/s sets the timing boundary before bandwidth or thermal limits appear.

How much power does the 1.1 V module draw and does it need active cooling in a Dell PowerEdge HS5610?

At 1.1 V the module runs within standard DDR5 power envelopes and the server's existing airflow is sufficient; no extra cooling is required.
