Dell PowerEdge R540 ECC RDIMM

This NEMIX RAM module is an 8 GB DDR4 2666 registered DIMM built for the Dell PowerEdge R540 rack server. It operates at 1.20 V with a CL19 latency and uses a 1Rx8 organisation across 288 pins. ECC and registered buffering provide the data-integrity required in production server environments.

Suited for single-slot capacity upgrades

Administrators expanding memory in a PowerEdge R540 will find this stick drops straight into a free slot without configuration changes. Systems that need unbuffered UDIMMs, non-ECC memory, or speeds above 2666 MT/s should look at a different module because this part is registered ECC only.

Handles typical virtualisation workloads

The 8 GB capacity and 2666 MT/s throughput comfortably run several virtual machines or container hosts on a single node. Workloads that demand larger per-socket footprints — such as in-memory databases or heavy analytics — will exhaust this module quickly and require higher-density RDIMMs.

Questions about this item

My Dell PowerEdge R540 currently runs single-rank DDR4 RDIMMs — will this 1Rx8 module install alongside them?

Yes, this is a single-rank 1Rx8 registered DDR4 DIMM, so it can populate the same channels as other 1Rx8 RDIMMs in your R540.

After seating the 288-pin DDR4 RDIMM, how do I confirm the server sees the full 8 GB at 2666 MT/s with ECC active?

Enter the BIOS or iDRAC on the R540 and verify total memory shows the new 8 GB module running at 2666 MT/s with ECC enabled.

What existing hardware must my Dell PowerEdge R540 already have for this 288-pin DDR4 RDIMM to function?

Your R540 needs an available DDR4 RDIMM slot and a processor that supports DDR4-2666 registered ECC memory.
