64GB DDR4 RDIMM for Dell PowerEdge C4140

This 64GB DDR4 2933MHz registered ECC module is built for the Dell PowerEdge C4140 rack server. It uses a 2Rx4 organisation and runs at 1.2V with CL21 latency. The single DIMM fits the 288-pin DDR4 slots used by that platform.

Registered DDR4 limited to one DIMM per channel

Registered DDR4 at 2933MHz typically allows only one rank-heavy DIMM per channel before the memory controller drops the data rate. The 2Rx4 layout on this module counts as two ranks, so filling every slot may force a lower speed. The 288-pin interface does not support DDR5 signalling.

2Rx4 rank layout decides maximum capacity per

The dual-rank x4 organisation is the specification that determines how many 64GB modules the C4140 can accept at the rated 2933MHz. Builders who need more memory per channel than this rank structure permits should verify the server’s qualified vendor list before ordering.

Questions about this item

Should I pick the single 64 GB module or build the capacity from smaller sticks?

The part is sold as one 64 GB DDR4 2933 MHz CL21 2Rx4 registered ECC RDIMM, so the capacity arrives in a single module.

What does the 2933 MHz rating deliver inside a Dell PowerEdge C4140?

The module runs at DDR4 2933 (PC4-23400) with CL21 latency, providing the rated throughput and error-corrected stability the server expects.

How does the 288-pin DDR4 RDIMM interface limit speed or capacity in this server?

The 288-pin registered DDR4 form factor locks the module to DDR4 signalling at 1.2 V, capping operation to the 2933 MHz spec the C4140 supports.
