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

Overview

The Dell SNP7JXF5C/128G is a 128GB DDR4 load-reduced DIMM (LRDIMM) designed to expand memory capacity in Dell servers while maintaining stability and power efficiency. Operating at 3200 MT/s, it supports high-bandwidth data processing and is optimized for demanding workloads such as virtualization, in-memory databases, and analytics platforms. Its 4-rank by 4-bit configuration and load-reduced buffering help reduce electrical load on the memory bus, enabling more DIMM slots to be populated without compromising performance.

Key features

• Load-reduced buffering technology that lowers electrical strain on the memory bus, allowing for higher memory density and improved scalability.
• High-speed operation at 3200 MT/s to support data-intensive applications and maintain fast system responsiveness.
• 4-rank by 4-bit organization that delivers dense memory capacity per module while preserving signal integrity.
• Automatic speed adjustment when mixed with other DIMMs to ensure system stability and compatibility during incremental upgrades.
• Thorough Dell qualification and testing to guarantee firmware compatibility, thermal performance, and reliable operation in supported servers.

Key specs

• Memory capacity: 128 GB
• Memory type: DDR4
• Speed: 3200 MT/s
• Module type: Load-reduced DIMM (LRDIMM)
• Organization: 4-rank x4

Compatibility and usage considerations

This memory module is specifically designed for Dell servers that support 3200 MT/s LRDIMM configurations. It is not compatible with 128GB 2666 MT/s modules or servers based on Intel Skylake processors, so verifying server support before purchase is essential. The module fits well in environments requiring large memory footprints such as virtualization hosts running multiple virtual machines, SAP HANA in-memory databases, analytics platforms handling large datasets, and virtual desktop infrastructure (VDI) setups demanding consistent performance.
