Dell 128GB DDR4 4Rx4 LRDIMM 3200 MT/s Memory Module

The Dell SNP7JXF5C/128G is a dual in-line memory module that provides 128GB of capacity, uses DDR4 technology, and features load-reduced buffering to ease electrical strain on the memory bus. It is purpose-built for Dell servers that need a substantial memory footprint without sacrificing stability or power efficiency.

Operating at up to 3200 megatransfers per second, the module employs a 4-rank by 4-bit organization to deliver dense capacity while preserving signal integrity. The integrated buffer reduces load on each channel, allowing administrators to populate more DIMM slots in a system and sustain reliable performance under heavy workloads.

Dell engineers qualify every unit for specific systems, verifying firmware compatibility, thermal behavior, and overall reliability. When mixed with lower-speed modules, this DIMM automatically adjusts to the highest common speed, making incremental upgrades straightforward in production environments.

The module is well-suited for virtualization hosts that run numerous virtual machines, in-memory databases such as SAP HANA, analytics platforms that keep large data sets in RAM, and VDI deployments that demand consistent response times. It is not compatible with 128GB 2666 MT/s modules or servers built on Intel Skylake processors, so confirming server support for 3200 MT/s LRDIMM before purchase is essential.
