Server Memory Upgrade

This 8 GB DDR4 module provides ECC error correction for servers and workstations that require data integrity. It operates at 2666 MHz with CL19 latency and standard 1.20 V power draw. The unbuffered design fits systems that accept UDIMMs rather than registered memory.

Replaces Micron MTA9ASF1G72AZ-2G6E1

This module is a compatible replacement for the Micron part number listed, matching its DDR4 2666 PC4-21300 specification and 1Rx8 organisation. The upgrade is worth it when your current configuration lacks ECC protection or runs below the 2666 MHz speed rating. Verify your platform supports unbuffered ECC UDIMMs before purchasing.

Capacity And Headroom

A single 8 GB stick handles typical virtualisation hosts, database nodes and multi-user application servers with moderate memory demands. Workloads that exceed this capacity per channel will require additional modules or higher-density DIMMs. The 288-pin DDR4 form factor limits use to platforms designed for this generation.

Questions about this item

Will the 288-pin DDR4 DIMM fit my server motherboard's standard DDR4 slots?

Yes, the module uses the standard 288-pin DDR4 DIMM form factor that fits any server or workstation board with DDR4 UDIMM slots.

Do I need to configure anything in the BIOS after installing this ECC unbuffered module, or is it plug-and-play?

It is plug-and-play; the 2666 MHz CL19 1.20 V JEDEC profile loads automatically, but you should verify the system reports ECC active in the BIOS or OS afterwards.

If a memory error appears years later, can I replace just this single 8 GB stick?

Yes, each 8 GB module is individually tested and covered by a lifetime warranty, so a single stick can be swapped without replacing a matched kit.
