Dell PowerEdge R7625 Compatibility

This 16GB DDR5 module is validated for Dell PowerEdge R7625 rack servers and other platforms that accept 288-pin registered ECC memory. It targets IT teams upgrading or populating enterprise systems with matched, stress-tested modules.

16GB Capacity with CL40 Latency

The single-rank 1Rx8 design delivers 16GB at 4800 MT/s (PC5-38400) with CAS latency 40. It handles virtualised workloads, database buffers and multi-threaded compute tasks, while capacity limits appear when datasets exceed available slots.

Registered ECC at 1.1V Without Heat Spreader

Registered buffering and on-die ECC protect data integrity in continuous operation. The module runs at 1.10V and relies on chassis airflow for cooling; acoustic impact is negligible in a populated server environment.

Questions about this item

Will the 1Rx8 DDR5 4800 module run with my existing RDIMMs in the Dell PowerEdge R7625?

Mixing ranks or speeds can prevent the server from posting; Dell recommends populating identical DDR5 4800 CL40 1Rx8 RDIMMs in matched channels for stable operation.

How can I verify the ECC RDIMM is operating at 4800 MT/s and CL40 after installation?

Enter the iDRAC or BIOS memory configuration screen; it will display each DIMM running at 4800 MT/s with CL40 timings and ECC active.

Does the 16 GB stick ship with a heat spreader or any extra mounting hardware?

The module has no heat spreader and includes only the RDIMM itself; no brackets, screws or cables are supplied.
