Dell PowerEdge R740xd 16GB RDIMM upgrade

This 16GB DDR4 2933MHz registered ECC module is built for the Dell PowerEdge R740xd server. It installs in a single 288-pin slot and operates at 1.2V with CL21 latency. The 2Rx8 organisation and PC4-23400 rating match the platform's memory subsystem.

Suited for administrators expanding R740xd capacity

IT teams adding memory to a Dell PowerEdge R740xd will find this module validated for that system. Buyers who need unbuffered UDIMMs, non-ECC memory, or a different pin count should look elsewhere. The registered design and ECC function are required by the target server.

288-pin DDR4 RDIMM form factor decides fit

Only systems that accept 288-pin DDR4 registered DIMMs with ECC can use this part. The physical keying, electrical signalling and register timing are fixed by the DDR4 RDIMM standard. Confirm the motherboard supports registered ECC modules before purchase.

Questions about this item

How much power does this 1.2V DDR4 2933 RDIMM draw under sustained load?

The module operates at 1.20 V, the standard DDR4 voltage, so power draw per stick is low and heat output is minimal in a fully populated R740xd.

Does the Dell PowerEdge R740xd need a specific BIOS revision or riser card to recognise this 288-pin ECC registered module?

The stick is built to Dell's MR23400-628K1 specification; the server's existing memory controller and DIMM slots accept it without extra hardware.

Will this CL21 2Rx8 stick work alongside older DDR4 RDIMMs already in the R740xd?

The R740xd memory controller runs all installed DIMMs at a common speed and timing; mixing ranks or CAS values is supported but the system will downclock to the slowest module.
