About the Micron DDR4 LRDIMM 64GB 4Rx4 2666 CL19 ECC Server Memory
The Micron DDR4 LRDIMM 64GB 4Rx4 2666 CL19 ECC Server Memory from Micron is enterprise-grade Memory (RAM) hardware built for data centers. It features 64 GB capacity, LRDIMM (288-pin) form factor, DDR4-2666 (PC4-21300) speed. The Micron MTA72ASS8G72LZ-2G6J2R is a 64 GB DDR4 Load-Reduced DIMM (LRDIMM) operating at 2666 MT/s with CL19-19-19 latency timings. Built on a 4-rank, x4 organization with a 72-bit bus width incorporating ECC, this module employs an on-DIMM memory buffer (iMB) that isolates the host memory controller from the individual DRAM loads — enabling higher memory capacities per channel without the electrical loading penalties that limit standard RDIMM configurations. The module confo Available in brand new condition. Micron memory (ram) products are trusted by enterprises and data centers worldwide. Available from Omnixon Global.
