The MTA36ASF4G72PZ-2G6B2 is a high-capacity DDR4 memory module from Micron, featuring a speed of 2666 MHz and a substantial capacity of 32GB. It is designed as a 4Gx72 ECC Reg/RDIMM (Registered DIMM) with a 2Rx4 configuration, indicating a dual rank layout which enhances performance by allowing multiple memory chips to operate in parallel. This module supports ECC (Error-correcting code) and is registered, which stabilizes the data signals by adding a register between the DRAM modules and the system's memory controller. This makes it particularly suitable for server and workstation applications where reliability and performance are paramount. With 288 pins and operating at DDR4-2666V, this module is compatible with a broad range of systems that require high-speed, ECC Registered memory, making it an excellent choice for system upgrades or builds that demand exceptional reliability and performance.
