Product overview
This is the HPE 16GB (1x16GB) single rank x8 DDR5-4800 CAS-40-39-39 EC8 registered smart Memory Kit (for ProLiant Gen11 servers), order code P43322-B21. 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.

What you get ordering this from us
Ordered by part number
The order is placed against P43322-B21, not against a description of it, so there is no room for a substitution you did not agree to.
Population mapped for you
Send the current DIMM layout and we return the slot map with the quote, so the modules go in the right order.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
Is P43322-B21 genuine and is the warranty intact?
Yes. It ships new in HPE packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
Will P43322-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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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.
