Dell PowerEdge XR2 memory upgrade

This NEMIX RAM module is a 32GB DDR4 2666 ECC RDIMM built for the Dell PowerEdge XR2 rack server. It runs at 1.2V with CL19 latency and a 2Rx4 rank configuration across 288 pins.

IT teams maintaining Dell PowerEdge XR2 servers

Administrators who need registered ECC memory for this specific platform will find the correct spec here. Builders working on consumer desktops, laptops or non-Dell servers should look elsewhere because the module is validated only for the named system.

2Rx4 rank organisation

The dual-rank x4 layout determines how the memory controller addresses the chips and is the single specification that decides whether this DIMM matches the server's qualified configuration.

Questions about this item

Should I choose the 32GB single module or look for a multi-module kit for the PowerEdge XR2?

This listing is a single 32GB module; add a second identical stick if your configuration calls for dual-channel population.

What does the 2666MHz rating deliver once installed in the server?

The module runs at DDR4 2666 (PC4-21300) with CL19 latency, giving the rated throughput when the system memory controller operates at that speed.

Is the 288-pin RDIMM interface limited by any specific standard in the XR2?

It uses the standard DDR4 RDIMM interface with ECC and registered buffering; the platform's memory controller determines the maximum supported frequency and capacity.
