Two manufacturers make modules at this exact specification. They match on every key parameter and are generally interchangeable: a buyer who needs "16 GB DDR4-2400 registered" can usually accept any of them.

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: Samsung or SK hynix. You choose from real offers.
