Micron MTA36ASF4G72PZ-2G6E1 Review

Micron's MTA36ASF4G72PZ-2G6E1 is the 2666MT/s speed bin of their widely-used 32GB DDR4 RDIMM part family, and it's exactly what you need if your server board's memory QVL specifically calls for 2666MHz rather than the more common 3200MHz bin.

Comparison to Alternatives

This shares the same base part family as Micron's own MTA36ASF4G72PZ-3G2R1 (32GB DDR4-3200 ECC RDIMM) already in this catalog, just binned for a lower speed. If your platform supports 3200MT/s, buy that one instead since it typically costs about the same; only choose this 2666MHz part when your specific server generation caps out there anyway.

Speed and Latency

The number that matters is true latency, not CL alone. Here it is 19 / (2666 / 2) x 1000 = 14.3ns.

Our verdict

Reviewed by Burooj Alam. Rated by us, not by users.

Expert rating7.4 / 10

The right, cost-effective choice specifically for first-generation Xeon Scalable and EPYC platforms capped at 2666MT/s, but check your platform ceiling before assuming this is the part you need.

Best for

  • Skylake-SP Xeon Scalable and 1st-gen EPYC (Naples) server upgrades
  • Cost-sensitive server capacity additions on older platforms
  • Exact-spec RDIMM replacements matching an existing 2666MHz server fleet

Not for

  • Newer Cascade Lake or EPYC Rome platforms that support 3200MT/s (buy the faster-rated part instead)
  • Consumer or gaming motherboards
  • UDIMM-only workstations
