The Micron MTA9ASF1G72PZ-3G2E2TI is an 8GB DDR4-3200 single-rank registered ECC memory module (RDIMM) engineered for enterprise server deployments. Built with Micron 8Gb E-die DRAM, it operates at a standard 1.2V JEDEC supply and delivers up to 25.6 GB/s memory bandwidth for high-reliability computing environments.
The MTA9ASF1G72PZ-3G2E2TI is architected on JEDEC-compliant DDR4 technology, utilizing nine 8Gb x8 monolithic DRAM packages arranged in a single-rank (1Rx8) layout across a 72-bit bus (64-bit data plus 8-bit sideband ECC). To preserve signal integrity at 3200 MT/s, the module integrates an onboard Registering Clock Driver (RCD), which buffers command, address, and clock inputs between the host memory controller and DRAM devices, reducing capacitive load on the memory bus.
Decoding the part number: 'MT' stands for Micron Technology, 'A' indicates DDR4 SDRAM, '9' specifies 9 DRAM packages, 'ASF' designates the standard-height RDIMM form factor, '1G72' reflects a 1G x 72 organization (8GB total), 'P' designates RDIMM buffering, 'Z' denotes RoHS/halogen-free packaging, '3G2' specifies DDR4-3200 speed (CL22 timing), and 'E2TI' indicates the 8Gb E-die revision and module hardware BOM revision.
Always verify against your server's qualified vendor list (QVL).
No. Server architectures strictly prohibit mixing registered DIMMs (RDIMMs), unbuffered DIMMs (UDIMMs), and load-reduced DIMMs (LRDIMMs) within the same system or memory channel.
Yes. The module is fully backwards-compatible and will automatically downclock to 2933 MT/s, 2666 MT/s, 2400 MT/s, or 2133 MT/s based on the integrated memory controller (IMC) capabilities and system BIOS configuration.
1Rx8 indicates a single-rank configuration using x8 width DRAM chips. Single-rank modules present lower electrical loading on the memory bus, allowing maximum DIMM-per-channel configurations, though they do not provide the rank interleaving benefits of 2Rx8 or 2Rx4 modules.
