Dell PowerEdge R740XD server upgrade

This 16 GB DDR4 2933 MHz ECC RDIMM module is built specifically for the Dell PowerEdge R740XD. It uses a 288-pin registered design with a 2Rx8 organisation and CL21 latency to match the platform's memory controller requirements.

Single-module kit simplifies capacity planning

The package contains one 16 GB stick, so administrators can add capacity in precise increments without populating unnecessary slots. Registered buffering and ECC protect data integrity in multi-socket workloads, while 1.20 V operation keeps power draw within Dell's validated envelope.

2933 MHz DDR4 speed defines compatibility

The module runs at PC4-23400 / DDR4 2933; systems that require a different DDR generation or a lower rated speed will not accept it. Verify the server's qualified-vendor list before ordering to ensure the memory controller supports this frequency.

Questions about this item

Will the 2Rx8 rank configuration need any firmware or BIOS updates on the PowerEdge R740XD over time?

The module follows the DDR4 2933 PC4-23400 standard; any required updates come from Dell firmware releases for the R740XD platform.

What limit appears first when the RDIMM runs continuously at 2933 MT/s in a fully populated server?

Sustained throughput is capped by the PC4-23400 data rate and the registered buffer latency of CL21.

How much heat and power does a single 1.2 V 16 GB stick produce during all-day operation?

At 1.20 V the module draws minimal power and has no heat spreader, so it relies on chassis airflow for cooling.
