Dell PowerEdge R7425 Memory Upgrade

This 64GB DDR4 LRDIMM module is built for the Dell EMC PowerEdge R7425 server. It targets IT teams who need to expand memory capacity in a validated, load-reduced configuration for enterprise workloads. The single-stick design lets administrators populate slots incrementally as demand grows.

ECC LRDIMM Build With 288-Pin Interface

The module uses a load-reduced registered design with on-board ECC to maintain data integrity under sustained server loads. A 288-pin DDR4 edge connector ensures direct compatibility with the R7425 memory slots, while the absence of a heat spreader keeps the profile low for dense chassis layouts. Major OEM DRAM from Samsung, Micron or Hynix underpins the assembly.

64GB 2666MHz CL19 At 1.2V

Capacity, speed and latency are fixed at 64GB, 2666MHz and CL19 with a 1.2V operating voltage. These three figures determine whether the module matches the server's qualified vendor list and the performance envelope your deployment requires.
