Dell PowerEdge C4140 memory upgrade

This 32GB DDR4 2933MHz ECC RDIMM is built for Dell PowerEdge C4140 rack servers. It delivers registered, error-correcting memory for stable operation in enterprise workloads. The single-module design fits one 288-pin slot and runs at 1.2V for standard server power envelopes. IT teams use it to expand capacity in compatible Dell platforms.

Thermals noise and power draw

The module operates at 1.20V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller during sustained use. No active cooling components are present, so acoustic output depends entirely on the host system fans. Power consumption scales with the 2933MHz data rate under typical server loads.

2Rx4 rank configuration decides fit

This unit uses a 2Rx4 organisation with CL21 latency at the PC4-23400 speed grade. Servers requiring a different rank layout or latency profile will not accept it. Buyers needing 1Rx4 or 2Rx8 modules must select a different part. The registered ECC design also prevents use in consumer desktop boards.

Questions about this item

How do I install this 288-Pin DDR4 RDIMM in a Dell PowerEdge C4140 and what step is often missed?

Power off the server, open the chassis, align the notch on the 288-Pin module with the slot key, press firmly until the ejector clips lock, then verify in BIOS that the 32GB 2Rx4 DIMM is recognised at 2933MT/s.

What maintenance or replacement will this ECC RDIMM need over its service life?

No routine maintenance is required; the module has no heat spreader and operates at 1.2V, so replacement is only necessary if a memory diagnostic reports an uncorrectable ECC error or if capacity must be increased.

What limit appears first when this 32GB CL21 2Rx4 module runs sustained workloads?

The CAS latency of CL21 at 2933MT/s sets the timing ceiling, and the registered 2Rx4 organisation limits maximum bandwidth before the memory controller becomes the bottleneck.
