Micron Memory Cross-Reference

Micron is one of only three companies left that actually manufacture DRAM — the silicon inside most server memory on the market, including a good deal of what ships under other brands. If you have a Micron part number in hand, find its match here.

How to read a Micron part number

MTA  18   ASF  2G72  PZ   -3G2
 │   │     │    │     │     │
 │   │     │    │     │     └─ speed grade
 │   │     │    │     └─────── module type
 │   │     │    └───────────── density × bus width
 │   │     └────────────────── product family
 │   └──────────────────────── DRAM device count
 └──────────────────────────── MTA = DDR4 · MTC = DDR5

Generation — MTA… is DDR4, MTC… is DDR5. That's the fastest way to tell them apart.

Device count tells you ECC. A count divisible by 9 — MTA9, MTA18, MTA36, MTA72, MTA144 — is a 72-bit ECC module. MTA8 and MTA16 are 64-bit non-ECC.

Module type

Speed grade — the code after the dash:

A trailing E1, R1 or F1 is a revision marker — MTA18ASF2G72PZ-3G2 and -3G2E1 are the same speed and interchange.

What we stock against Micron parts: ECC Registered RDIMM, Load-Reduced LRDIMM, ECC UDIMM and ECC SODIMM, DDR4 2133 through 3200 and DDR5 4800 through 6400, in densities from 8GB to 256GB.
