The Micron MTA9ASF1G72PZ-2G9E1UI is an enterprise-grade 8GB DDR4-2933 PC4-23400 Registered DIMM designed for high-availability server and workstation environments. Operating at standard DDR4 1.2V, this single-rank x8 (1Rx8) memory module provides full ECC data protection to prevent single-bit errors and system crashes. It is built to deliver predictable memory throughput and low latency across dual- and multi-socket enterprise platforms.
The MTA9ASF1G72PZ-2G9E1UI is built on DDR4 JEDEC-compliant standard architecture utilizing nine 8Gb monolithic DRAM components arranged in a single rank (1Rx8). Eight dies are allocated for the standard 64-bit data path, while the ninth provides 8 bits of sideband Error-Correcting Code (ECC) storage, forming a 72-bit wide bus. It incorporates an onboard Registering Clock Driver (RCD) to buffer command, address, and clock signals, reducing electrical load on the host memory controller and ensuring high signal integrity at 2933 MT/s.
The Micron part number decodes systematically: 'MTA' designates Micron Technology Assembly; '9' indicates 9 DRAM packages per module; 'ASF' specifies the 288-pin standard RDIMM form factor layout; '1G72' indicates a module organization of 1GB x 72 bits (8GB capacity); 'P' identifies it as an RDIMM; 'Z' marks RoHS-compliant packaging; '-2G9' denotes the DDR4-2933 speed rating (PC4-23400); 'E1' indicates the 8Gb E-die revision; and the terminal suffix 'UI' denotes commercial/enterprise temperature grade and internal manufacturing revision.
Always verify against your server's qualified vendor list (QVL).
Yes. The JEDEC SPD profiles programmed on this module allow it to automatically clock down to 2666 MT/s, 2400 MT/s, or 2133 MT/s depending on the processor generation and population rules.
While most enterprise memory controllers permit mixing ranks across different memory channels, mixing x8 and x4 modules within the same channel is generally not supported. For optimal performance and stability, populate identical capacities, ranks, and chip organizations across all channels.
No. The MTA9ASF1G72PZ-2G9E1UI is a Registered DIMM (RDIMM) requiring a server-grade motherboard and CPU memory controller that supports registered memory. It is incompatible with standard desktop motherboards requiring UDIMMs.
The MTA9ASF1G72PZ-2G9E1UI is a TAA-compliant enterprise server memory module (8GB DDR4-2933 RDIMM 1RX8 1.2V). Sold as certified refurbished with a 1-year warranty and same-day US shipping when in stock. We stock 2 units of this SKU today.
