Micron MTA72ASS8G72LZ-2G6B2SG 64GB DDR4-2666 ECC Load Reduced LRDIMM Server Memory
Product Description
Upgrade your enterprise infrastructure with the Micron MTA72ASS8G72LZ-2G6B2SG 64GB DDR4-2666 ECC Load Reduced (LRDIMM) Server Memory, engineered to deliver exceptional reliability, scalability, and performance for modern data centers and mission-critical server environments. Built using genuine Micron DRAM components, this enterprise-grade memory module is designed for virtualization, cloud computing, enterprise databases, storage systems, and high-performance computing (HPC).
Featuring a 64GB capacity operating at 2666MT/s (DDR4-2666 / PC4-2666V / PC4-21300), the MTA72ASS8G72LZ-2G6B2SG provides the high memory bandwidth and density required by demanding enterprise workloads. Designed for continuous 24/7 operation, it delivers dependable performance and long-term stability for business-critical applications.
The module incorporates ECC (Error Correcting Code) technology to automatically detect and correct single-bit memory errors, helping protect valuable business data while improving overall system reliability. As a Load Reduced DIMM (LRDIMM), it minimizes the electrical load on the memory controller, enabling servers to support higher memory capacities without compromising performance or stability.
Its 4Rx4 quad-rank architecture provides an excellent balance of memory capacity, bandwidth, and scalability for memory-intensive workloads. Operating at an energy-efficient 1.2V with CL19 latency, this module helps reduce power consumption while maintaining outstanding enterprise-class performance.
The SG suffix identifies a Micron manufacturing/component revision and does not affect the module’s electrical specifications, compatibility, or overall performance. Every Micron server memory module undergoes rigorous quality testing to ensure maximum compatibility, durability, and long-term reliability.
Whether you’re upgrading existing server memory or deploying new enterprise infrastructure, the Micron MTA72ASS8G72LZ-2G6B2SG delivers the trusted quality and performance expected from one of the world’s leading memory manufacturers.
