32GB DDR4 ECC Registered RDIMM

This 32GB DDR4 module is built for Dell PowerEdge servers including the FC640, M640, MX740c, MX840c and R450. It delivers error-correcting, registered memory for workloads that require data integrity and platform stability.

Registered ECC with 2Rx4 organisation

The single specification that decides fit is the registered ECC design with 2Rx4 ranking; this memory will not work in standard desktop computers and cannot be mixed with unbuffered modules.

32GB capacity at 2933MHz with backward support

At 32GB per DIMM the kit handles large virtualisation and database tasks comfortably, while the 2933MHz CL21 rating also runs at 2666MHz, 2400MHz and 2133MHz where the platform requires it.

Perguntas sobre este artigo

How does the 2933MHz speed behave when installed in a Dell PowerEdge R450?

The module runs at its rated 2933MHz CL21 in the R450; if the platform configures a lower memory bus it will down-clock automatically to 2666MHz, 2400MHz or 2133MHz while keeping ECC and registered operation intact.

What does the PC4-23400 designation limit in practice?

PC4-23400 is the JEDEC peak transfer rate for DDR4-2933; the actual throughput in a server is capped by the processor's memory controller and the number of populated channels, not by the module rating itself.

Will the 288-pin registered DIMM fit the MX740c blade slot?

Yes — the MX740c uses standard 288-pin DDR4 RDIMM sockets, so this 32GB 2Rx4 module seats directly without an adapter or low-profile bracket.
