Dell PowerEdge R640 memory upgrade

This 16GB DDR4 RDIMM is built for the Dell PowerEdge R640 server. It delivers registered ECC memory that maintains data integrity in enterprise workloads. The module fits directly into the 288-pin slots without extra configuration. It targets administrators who need reliable capacity expansion for virtualisation or database tasks.

Sustained-load behaviour

Registered buffering and ECC correction keep error rates low during continuous operation. The 1.2V operating voltage limits heat output while the CL21 latency supports steady throughput. Dual-rank 2Rx8 organisation allows the memory controller to interleave accesses across banks. These traits help the server maintain consistent performance under prolonged heavy loads.

Deciding specification

The module runs at DDR4 2933 (PC4-23400) with a CAS latency of 21. This speed and timing combination must match the R640 memory controller settings for the system to post and run stably. If the platform requires a different data rate or latency the DIMM will not operate correctly.

Perguntas sobre este artigo

How much power does a single 16 GB DDR4 2933 ECC RDIMM draw at 1.2 V when the server runs continuously?

The module operates at 1.2 V, the standard DDR4 voltage, so power draw stays low even under sustained load in a Dell PowerEdge R640.

What must the Dell PowerEdge R640 already have for this 288-pin RDIMM to be recognised?

The R640 needs free DDR4 RDIMM slots, a BIOS that supports 2933 MT/s registered ECC memory, and the correct population order for 2Rx8 modules.

Will this 2933 MHz CL21 registered ECC stick work alongside slower DDR4 RDIMMs already installed in the R640?

Yes — the server will clock all modules to the lowest common speed and latency, so existing slower RDIMMs remain compatible.
