Dell PowerEdge R7425 compatible DDR4 RDIMM

This 8 GB registered ECC module is built for Dell EMC PowerEdge R7425 servers and workstations. It installs in a 288-pin DDR4 slot and operates at 1.20 V. The single-rank 1Rx8 organisation keeps signal loading low for stable operation in dense memory configurations.

Sustained-load behaviour with ECC registered design

The registered buffer reduces electrical load on the memory controller during continuous workloads. ECC circuitry detects and corrects single-bit errors without halting the system. CL19 latency at 2666 MT/s delivers predictable throughput for virtualisation, database and compute tasks that run for hours.

8 GB capacity per module decides fit

Each stick provides exactly 8 GB, so total system memory scales in 8 GB increments. Buyers needing larger per-slot densities or non-ECC unbuffered memory for consumer platforms cannot use this part.

Questions about this item

How much power does the 1.2 V DDR4 module draw when the server runs continuously?

The module operates at 1.20 V, the standard DDR4 voltage, so power draw stays low even under sustained 2666 MT/s loads.

What must the system already have to accept this 288-pin RDIMM?

A Dell EMC PowerEdge R7425 (or compatible Dell server) with free DDR4 RDIMM slots that support ECC registered memory.

Will this CL19 1Rx8 stick work alongside older DDR4 ECC RDIMMs already installed?

Yes, if the existing modules are also DDR4 2666 ECC registered; the server will run all sticks at the lowest common speed and latency.
