Dell PowerEdge R740 compatible memory

This 16 GB DDR4 RDIMM is built for the Dell PowerEdge R740 rack server. It targets administrators who need to expand capacity in a validated configuration. The registered ECC design supports data integrity in production environments. Installation follows standard DIMM-slot procedures.

16 GB capacity with dual-rank layout

The module provides 16 GB in a single 2Rx8 rank, giving the memory controller two ranks per channel for improved bandwidth utilisation. At DDR4 2933 MT/s and CL21 latency it handles typical virtualisation and database workloads. Headroom is limited by the single-module density and the platform's maximum supported speed.

Registered ECC at 1.2 V

The module operates at 1.20 V with on-DIMM register and ECC circuitry. This combination is required by the R740 memory subsystem; unbuffered or non-ECC DIMMs will not function. The 288-pin DDR4 form factor matches the server's slots exactly.

Questions about this item

Will this 2933 MHz DDR4 RDIMM work alongside the memory already installed in my PowerEdge R740?

The module is built to Dell PowerEdge R740 specifications, so it is compatible with the server's memory architecture.

How can I confirm the module is running at 2933 MHz with CL21 timings after installation?

Check the system BIOS or use a tool such as CPU-Z to verify the reported speed of 2933 MHz and CAS latency of 21.

What comes in the package and is anything else required to install it?

The box contains one 16 GB 288-pin DDR4 RDIMM; no additional parts are needed for installation.
