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

Overview

The Dell SNP4JMGMDG/64G is a 64 GB DDR4 LRDIMM memory module designed to expand the memory capacity of compatible Dell PowerEdge servers. Operating at 2666 MHz with PC4-21300 specifications, it provides the bandwidth necessary for demanding workloads such as virtualized environments, in-memory databases, and high-performance computing. Its load-reduced design and quad-rank architecture enable higher memory density and stable performance even when all memory slots are populated.

Key features

• Load-reduced technology reduces electrical load on the processor, allowing greater memory capacity per channel and improved stability.
• Quad-rank architecture increases memory density, enabling large memory footprints in servers with limited DIMM slots.
• Error-correcting code (ECC) detects and corrects bit-level errors to maintain data integrity and minimize downtime in critical applications.
• Operates at a low voltage of 1.2 V to help reduce power consumption without sacrificing performance.
• Qualified and validated for Dell PowerEdge C4140 and C6420 servers, ensuring compatibility and reliable operation.
• Simple installation process compatible with standard 288-pin LRDIMM slots for quick upgrades.
