Micron MTA72ASS16G72LZ-3G2T - 128 GB - DDR4 - 3200 MHz - 288-pin DIMM

Server memory bottlenecks can cripple virtualization, database, and high-performance computing workloads. The Micron MTA72ASS16G72LZ-3G2T is a 128GB DDR4-3200 registered ECC module engineered for enterprise servers and workstations that demand maximum capacity and reliability. This quad-rank RDIMM uses 4Gbit x4 DRAM components to deliver 128GB on a single module, reducing the number of DIMM slots needed for large memory configurations. With error-correcting code (ECC), it detects and corrects single-bit memory errors, preventing data corruption and system crashes in mission-critical environments.

Who is it for

IT administrators and system builders deploying memory-intensive applications such as in-memory databases, large-scale virtualization, AI/ML training, and scientific computing. It is compatible with server platforms that support DDR4 registered DIMMs, including Intel Xeon Scalable and AMD EPYC series.
