MTA72ASS8G72LZ-2G6 Micron 64GB DDR4 LRDIMM
MTA72ASS8G72LZ-2G6 is a 64GB DDR4-2666 ECC Load-Reduced DIMM manufactured by Micron. This 288-pin server memory module is designed for compatible servers and enterprise systems that support high-capacity DDR4 LRDIMM memory.
The module operates at 2666 MT/s with a standard DDR4 voltage of 1.2V. In addition, its quad-rank 4Rx4 organization and load-reduced architecture help compatible systems support higher memory capacities while reducing the electrical load placed on the memory channel.

Is MTA72ASS8G72LZ-2G6 Compatible With My Server?
Before ordering, verify that your server supports 288-pin DDR4-2666 ECC Load-Reduced DIMM memory and 64GB modules. This product is not interchangeable with standard desktop UDIMM, ECC UDIMM, registered RDIMM or laptop SODIMM memory.
Although RDIMM and LRDIMM modules are both designed for servers, they use different buffering architectures. Therefore, most systems do not permit RDIMM and LRDIMM memory to operate together. Check the server manual or system memory configuration guide before combining modules.
For best results, match the complete part number, capacity, speed, voltage, rank and module type with the existing memory. However, the module may operate below 2666 MT/s when limited by the processor, motherboard or installed memory configuration.
