Micron 16GB DDR4-2666 ECC UDIMM 2Rx8 — MTA18ASF2G72AZ-2G6E2R

The Micron MTA18ASF2G72AZ-2G6E2R is a 16GB DDR4-2666 ECC Unbuffered DIMM (UDIMM) operating at 2666MHz (PC4-21300) with CL19 latency at 1.2V in Dual Rank x8 configuration. The E2R suffix identifies a specific production revision of the MTA18ASF2G72AZ-2G6 base part for server QVL qualification and traceability.

Key Features

  • E2R production revision — specific QVL qualification variant
  • ECC Unbuffered — error correction without register buffer
  • Genuine Micron server memory

Product Specifications

  • Part Number: MTA18ASF2G72AZ-2G6E2R
  • Manufacturer: Micron
  • Base Part: MTA18ASF2G72AZ-2G6

  • ECC: Single-bit error correction, multi-bit error detection
  • Buffer Type: Unbuffered — no register between controller and DRAM

Use Cases

  • Workstations and entry-level servers requiring E2R revision qualification
  • Platforms where server QVL specifies E2R revision explicitly
  • Intel Xeon E and AMD EPYC ECC UDIMM deployments

Compatibility

  • Intel Xeon E ECC UDIMM platforms
  • AMD EPYC and Ryzen Pro platforms supporting ECC UDIMM
  • Not compatible with RDIMM-only enterprise server platforms
  • Verify server QVL for E2R revision qualification

Frequently Asked Questions

What does the E2R suffix mean?
E2R is a production revision identifier for the MTA18ASF2G72AZ-2G6 base part. Electrical specifications are identical — the suffix tracks manufacturing revision for server QVL qualification and traceability.
What is the difference between MTA18ASF2G72AZ-2G6E2R and MTA18ASF2G72AZ-2G6?
Identical electrical specifications. Some server QVLs qualify specific revisions — check your server vendor's memory compatibility list.
Is E2R a Renesas register variant?
No. In the MTA18ASF UDIMM family the R in E2R denotes a production revision, not a Renesas register component (which applies to RDIMM families).

The Micron MTA18ASF2G72AZ-2G6E2R delivers 16GB DDR4-2666 ECC UDIMM in 2Rx8 configuration — the E2R production revision of MTA18ASF2G72AZ-2G6 for server QVL-specific deployments on Intel Xeon E and AMD EPYC platforms.
