Description
The Micron MTA72ASS16G72LZ-2G9B3R is a high-capacity 128GB DDR4 Load-Reduced DIMM (LRDIMM). LRDIMMs are specifically designed for servers that require the maximum possible memory capacity and density. They utilize an additional register chip that buffers both command/address and data signals, significantly reducing the electrical load on the memory controller. This allows for more memory modules to be installed in a system and for higher capacities per module to be achieved. This module operates at a speed of 2933MHz (PC4-23400), offering substantial memory bandwidth crucial for memory-intensive enterprise applications such as large databases, in-memory analytics, and virtualization. The 4Rx4 configuration indicates that the module is quad-rank, with each rank using four memory chips per chip select. This high rank count, combined with the LRDIMM architecture, enables extreme memory capacities in compatible server platforms. With a standard DDR4 voltage of 1.2V, this module is energy-efficient for its capacity. It supports ECC (Error-Correcting Code) functionality, which is standard for LRDIMMs and essential for maintaining data integrity in critical server environments. The Micron MTA72ASS16G72LZ-2G9B3R is the ideal choice for servers requiring massive amounts of RAM to handle demanding workloads and large datasets.
