MTA18ASF2G72PZ-2G6 Micron 16GB DDR4-2666 ECC RDIMM
MTA18ASF2G72PZ-2G6 is a 16GB DDR4-2666 registered ECC RDIMM manufactured by Micron. This 288-pin server memory module is designed for compatible servers, enterprise workstations, storage appliances and data-center platforms that support registered DDR4 memory.
The module operates at 2666 MT/s with CL19 timing and the standard DDR4 voltage of 1.2V. In addition, its registered ECC architecture supports memory-error detection and correction in compatible systems. Its single-rank 1Rx4 organization is intended for server platforms that support this specific module configuration.

Is MTA18ASF2G72PZ-2G6 Compatible With My System?
Before ordering, verify that your server or workstation supports 288-pin DDR4-2666 registered ECC RDIMM memory. A DDR4 slot alone does not confirm compatibility. The processor, chipset, motherboard and firmware must support registered ECC modules.
This module is not interchangeable with non-ECC UDIMM, ECC UDIMM, SODIMM or LRDIMM memory. RDIMMs and LRDIMMs should not be mixed unless the system manufacturer explicitly documents support for that configuration.
This module uses a single-rank 1Rx4 organization. The “1R” designation means the module contains one logical rank, while “x4” describes the width of its DRAM devices. It does not indicate the number of modules included. Each unit ordered includes one 16GB RDIMM.
When adding this module to existing memory, compare the complete part number and match the capacity, speed, ECC type, registered architecture, rank and device organization. For best results, follow the server manufacturer’s approved memory population rules and qualified-vendor list.
