32GB DDR4 ECC UDIMM for Servers

This 32GB DDR4 2666 ECC UDIMM module targets administrators expanding memory in compatible server and workstation platforms. It uses an unbuffered design with ECC to protect data integrity in continuous workloads. The single DIMM simplifies filling empty slots without disturbing existing banks.

Best suited for verified slot upgrades

Buyers who need this exact Micron MTA18ADF4G72AZ-2G6 equivalent should confirm their system accepts DDR4 2666 ECC UDIMM 2Rx8 modules at 1.20V. Systems requiring registered DIMMs, lower densities, or different speeds cannot use this part.

Critical spec is ECC UDIMM 2Rx8 at DDR4 2666

The module is an unbuffered ECC DIMM with a 2Rx8 organisation running at DDR4 2666 (PC4-21300) CL19. That combination of ECC type, rank structure and speed determines whether the memory will post and operate correctly in the target platform.

Questions about this item

What DDR4 standard and peak transfer rate does this ECC UDIMM run at?

It operates at DDR4 2666 MHz, rated PC4-21300, with a CAS latency of CL19 at 1.20 V.

What physical slot and pin count does this 32 GB module require?

It fits a standard DDR4 DIMM slot with 288 pins and uses a 2Rx8 unbuffered layout.

How is the module installed and which orientation mistake is common?

Align the off-centre notch on the 288-pin edge connector with the slot key, press straight down until both retention clips click, and avoid forcing it in backwards.
