Two manufacturers make modules at this exact specification. They match on every key parameter and are generally interchangeable: a buyer who needs "128 GB DDR4-3200 registered" can usually accept any of them.
| Manufacturer | Part number | CAS | OEM refs | Data |
|---|---|---|---|---|
| Micron | MTA36ASF16G72PZ-3G2R1TI | — | — | specs |
| Samsung | M393AAG40M32-CAECO | — | — | specs |
Practical rule: servers accept these modules interchangeably in almost all cases. Keep one vendor within a memory bank and match existing modules when expanding, rather than mixing brands side by side.
Post a request for this spec and VAT-verified suppliers quote whichever brand they actually stock: Micron or Samsung. You choose from real offers.
