32GB DDR4 2666 ECC UDIMM

This 32GB DDR4 2666 ECC UDIMM module is built for servers and workstations that require error-correcting memory. It operates at 1.20V with CL19 latency and uses a 2Rx8 rank configuration on Micron chipset. The unbuffered design fits standard 288-pin DIMM slots in compatible enterprise platforms.

Replaces Micron MTA18ADF4G72AZ-2G6B2

This module serves as a direct replacement for the Micron MTA18ADF4G72AZ-2G6B2 part number. The upgrade is worth it when your system supports DDR4 2666 ECC unbuffered memory and you need to expand capacity with a validated equivalent. Verify your platform specifications before purchase to ensure compatibility.

32GB capacity for virtualization and databases

The 32GB capacity comfortably handles virtualization hosts, database workloads, and multi-user application servers. Headroom exists for moderate concurrent workloads and memory-intensive services. It runs out when workloads demand higher density per slot, faster DDR4 speeds, registered ECC modules, or total system memory beyond what your motherboard's slot count allows.

Questions about this item

Will this 288-pin DDR4 DIMM fit my server's standard memory slots?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor required by compatible server and workstation motherboards.

Do I need to populate specific DIMM slots or channels when installing this 2Rx8 ECC module?

Install the module in the slot designated by your system manual for single-module or channel-specific population; the common error is ignoring the motherboard's required slot order.

How can I verify long-term reliability of the Micron chipset on this 32 GB module?

The Micron chipset undergoes A-Tech's quality assurance testing and is covered by a lifetime warranty for the original purchaser.
