Micron 16GB DDR4-2666 ECC RDIMM 2Rx8 — MTA18ASF2G72AZ-2G6E2ZI

The Micron MTA18ASF2G72AZ-2G6E2ZI is a 16GB DDR4-2666 ECC Registered DIMM (RDIMM) operating at 2666MHz (PC4-21300) with CL19 latency at 1.2V in Dual Rank x8 configuration. Despite sharing the MTA18ASF2G72AZ base part number the ZI suffix designates this as a registered RDIMM with industrial temperature qualification — not a UDIMM.

Key Features

  • ECC Registered (RDIMM) — register buffer for enterprise server signal integrity
  • ZI suffix — registered industrial temperature range variant
  • Dual Rank x8 (2Rx8)
  • Genuine Micron server memory

Product Specifications

  • ECC: Single-bit error correction, multi-bit error detection
  • RAS Features: ECC, registered buffer

Use Cases

  • Enterprise servers requiring DDR4-2666 ECC RDIMM 2Rx8
  • Industrial and telecom platforms requiring extended temperature RDIMM
  • Embedded server and networking infrastructure requiring industrial-grade DRAM

Compatibility

  • DDR4 RDIMM slots on Intel Xeon Scalable (LGA3647) and AMD EPYC DDR4 platforms
  • Not compatible with UDIMM-only platforms
  • Verify server QVL before installation

Frequently Asked Questions

Why does MTA18ASF2G72AZ-2G6E2ZI have RDIMM type despite the AZ base part typically indicating UDIMM?
The ZI suffix overrides the base part classification — this variant is a registered RDIMM with industrial temperature qualification. Always verify the full part number when selecting memory type.
What does the ZI suffix mean?
Z indicates registered (RDIMM) and I indicates industrial temperature range — qualified for extended operating temperatures beyond standard commercial range.
What is the difference between MTA18ASF2G72AZ-2G6E2ZI and MTA18ASF2G72AZ-2G6E2R?
MTA18ASF2G72AZ-2G6E2ZI is an ECC RDIMM with industrial temperature qualification. MTA18ASF2G72AZ-2G6E2R is an ECC UDIMM. They require different platform support.

The Micron MTA18ASF2G72AZ-2G6E2ZI delivers 16GB DDR4-2666 ECC registered server memory in 2Rx8 configuration with industrial temperature qualification — the ZI registered variant for enterprise servers and industrial platforms requiring DDR4-2666 RDIMM.
