Dell 64GB DDR4 LRDIMM 288-pin 2666 MHz PC4-21300 Memory Module

The Dell SNP4JMGMDG/64G is a 64 GB DDR4 LRDIMM that lets you expand the memory pool of compatible Dell PowerEdge servers without sacrificing stability. Running at 2666 MHz and conforming to the PC4-21300 specification, it delivers the bandwidth that virtualized workloads, in-memory databases, and high-performance computing nodes rely on for low-latency access to data.

This module uses load-reduced technology, which places a buffer between the DRAM and the memory controller. By easing the electrical load on the processor, it allows higher overall memory capacity per channel and steadier performance when every slot is populated. Quad-rank architecture further increases density, so you can achieve large memory footprints in systems that have limited DIMM slots.

Error-correcting code is built in, helping detect and correct the bit-level errors that can interrupt services or corrupt data. For IT teams that run mission-critical applications or manage virtual machines around the clock, this added layer of protection helps keep downtime to a minimum.

Installation is straightforward for anyone familiar with server maintenance. Slide the module into a 288-pin LRDIMM slot, power up, and the system firmware will recognize the added capacity automatically. The memory is qualified for Dell PowerEdge C4140 and C6420 platforms, making it a direct, worry-free upgrade for those models.
