Dell PowerEdge R7425 32 GB DDR4 ECC RDIMM

This 32 GB DDR4 2666 registered DIMM is built for the Dell PowerEdge R7425 server. It uses ECC and registered buffering to maintain data integrity under continuous workloads. The module installs in a single 288-pin slot and runs at 1.20 V. System administrators expanding memory in this specific platform will find it a direct fit.

2666 MT/s DDR4 288-pin registered ECC

The decisive specification is the DDR4 2666 (PC4 21300) registered ECC interface with CL19 latency. Only systems that accept 288-pin RDIMMs at this speed and voltage can use the module. Buyers whose servers require a different speed, unbuffered DIMMs or non-ECC memory cannot install this part.

Single-module 32 GB kit with lifetime warranty

The package contains one 32 GB module, eliminating the need to match multiple sticks for this capacity. A lifetime warranty covers the module for the duration of ownership. No additional software, cables or cooling accessories are included.

Questions about this item

What does the 2666 MHz speed mean for my PowerEdge R7425?

The module runs at DDR4 2666 (PC4 21300) with CL19 latency and 1.20 V, delivering the rated throughput when installed in a compatible server.

How does the 288-pin DDR4 interface limit performance?

The 288-pin DDR4 RDIMM form factor caps operation to the DDR4 2666 standard and registered signalling required by the R7425 memory controller.

Will the 30 mm module height clear the R7425 DIMM slots?

The stick measures 133 mm long, 30 mm high and 3 mm thick, matching the standard 288-pin RDIMM profile for the PowerEdge R7425.
