Three manufacturers make modules at this exact specification. They match on every key parameter and are generally interchangeable: a buyer who needs "32 GB DDR4-2133 registered" can usually accept any of them.
| Manufacturer | Part number | CAS | OEM refs | Data |
|---|---|---|---|---|
| Micron | MTA36ASF4G72PZ-2G1B1RK | — | Crucial | specs |
| Samsung | M393A4K40BB0-CPB | — | Dell | specs |
| Samsung | M393A4K40BB0-CPB0Q | — | — | specs |
| SK hynix | HMA84GR7AFR4N-TF | — | HP | specs |
| SK hynix | HMA84GR7MFR4N-TF | — | Dell | 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, Samsung or SK hynix. You choose from real offers.
