Dell PowerEdge R540 DDR4 ECC RDIMM

This 16 GB DDR4 2666 MHz module is built for the Dell PowerEdge R540 rack server. It uses registered ECC technology to protect data integrity in continuous workloads. The single 288-pin DIMM installs directly into an available memory slot.

IT teams maintaining R540 fleets

Administrators who need validated, registered ECC memory for a Dell PowerEdge R540 will find this module matches the system requirements. Builders assembling custom white-box servers or upgrading consumer desktops should look elsewhere because this part is qualified only for the named Dell platform.

Registered ECC with 2Rx8 organisation

The module operates at 1.2 V with CL19 latency and a dual-rank 2Rx8 layout using major OEM DRAM. That combination of registration, error correction and rank structure determines whether the R540 memory controller will accept the DIMM at full 2666 MT/s speed.
