Purpose-built server memory

This 16GB DDR4 module is built for the Dell PowerEdge R740 and operates at 2933 MT/s with CL21 latency. It uses registered ECC circuitry and a 2Rx8 organisation to maintain data integrity in multi-socket server workloads.

Sustained-load behaviour

Registered buffering and ECC correction keep signal quality stable across all ranks during continuous read and write cycles. The 1.20V operating voltage limits thermal output so the module stays within spec inside dense chassis airflow paths.

Deciding specification

The 288-pin RDIMM form factor with 2Rx8 rank layout is the single attribute that determines whether this part fits the memory slots and population rules of the target platform. Buyers who need unbuffered UDIMM or a different rank configuration must select another module.

Questions about this item

How much power does the 1.2V DDR4 RDIMM draw when the Dell PowerEdge R740 runs continuously?

The module operates at 1.20V, the standard voltage for DDR4 registered memory, so power draw stays within the server's normal memory budget during all-day operation.

What must the Dell PowerEdge R740 already have for this 288-pin ECC RDIMM to function?

The R740 needs free DDR4 RDIMM slots and a BIOS that supports 2933 MT/s registered ECC modules; the memory plugs directly into the existing 288-pin DIMM sockets.

Will this 2Rx8 CL21 stick work alongside older DDR4 RDIMMs already installed in my R740?

Yes, provided the existing modules are also DDR4 registered ECC; the server will run all populated channels at the lowest common speed and latency.
