Product overview
HPE lists P62604-B21 as a 64GB (1x64GB) dual rank x4 DDR5-4800 CAS-40 registered smart Memory (for ProLiant Gen11 / apollo Gen11 AMD servers). Registered, load-reduced and unbuffered modules are not interchangeable, and a board that accepts one will refuse to post on another. Send the server model and we will check it against the supported-DIMM list before you order.
Quotes are itemised down to the accessories, so nothing that is needed to make the part work is left off and discovered later.

A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
Is P62604-B21 genuine and is the warranty intact?
Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
Will P62604-B21 work in my server?
Send the server model and a list of the DIMMs already fitted. Rank, voltage and population order all have to agree, and a module that is electrically compatible can still be unsupported in a given slot. We map the population before you order.
Do you accept purchase orders and quote at volume?
Yes, POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

Specifying a system, not just the part?
Host memory on an AI node is normally sized against accelerator memory, so the model and its working set both fit.
