Dell PowerEdge R540 memory upgrade

This 32GB DDR4 2666 ECC RDIMM is built for the Dell PowerEdge R540 rack server. It delivers registered, error-correcting memory for stable operation in enterprise environments. The module runs at 1.2V with CL19 latency and uses a 2Rx4 rank configuration. It is a new, single-module kit ready for immediate installation.

288-pin RDIMM slot requirement

The module fits a standard 288-pin DDR4 RDIMM slot and requires a server platform that supports registered ECC memory. It frees the system from relying on lower-capacity or non-ECC modules that cannot meet data-integrity demands. No heat spreader is present, so airflow in the chassis handles cooling directly.

IT teams running Dell PowerEdge R540 servers

This suits administrators who need a validated 32GB replacement or expansion module for the R540. It is not for desktop PCs, laptops or workstations that use unbuffered memory. Builders needing non-ECC, SODIMM or DDR5 modules should look elsewhere.
