Dell PowerEdge C4140 memory upgrade

This 16GB DDR4 2933 ECC RDIMM module is built for the Dell PowerEdge C4140 server. It delivers registered error-correcting memory that helps maintain data integrity in demanding workloads. The single 2Rx8 rank design fits a standard 288-pin slot and runs at 1.2V.

Who should buy this and who should not

This module suits administrators expanding memory in a compatible Dell PowerEdge C4140. It is not for desktop PCs, laptops or consumer motherboards that require unbuffered non-ECC DIMMs. Buyers needing higher capacities per slot or different speeds should verify their platform requirements first.

Deciding specification: registered ECC DDR4 2933

The registered ECC DDR4 2933 interface with CL21 latency determines compatibility. Only systems that accept 288-pin RDIMM modules at this speed and voltage will recognise the memory. Check your server documentation before ordering.

Questions about this item

Should I choose the 16 GB single module or add multiple sticks for the PowerEdge C4140?

This is a single 16 GB 2Rx8 registered ECC RDIMM; populate the C4140 DIMM slots in matched sets per channel following the server's memory configuration guide for optimal bandwidth.

What does the DDR4 2933 speed rating deliver inside the C4140?

The module runs at DDR4 2933 (PC4-23400) with CL21 latency at 1.2 V, providing the maximum rated throughput the C4140 memory controller supports for registered ECC DIMMs.

How does the 288-pin RDIMM interface limit installation options?

The 288-pin DDR4 RDIMM form factor fits only registered ECC DIMM slots; it cannot be used in unbuffered UDIMM slots or in systems requiring LRDIMM or 260-pin SO-DIMM modules.
