Product overview
P69721-1A1 is an HPE 64GB DDR5 6400MHz ECC RDIMM smart Memory Kit. Memory is the part most often ordered wrong, because rank, voltage and population rules differ per platform and per slot. This module is DDR5. Give us the server model and the DIMMs already fitted and we will confirm the configuration is supported.
Send a photo or a dump of the current DIMM layout and we will map the population for you before you order.

What you get ordering this from us
Ordered by part number
P69721-1A1 is what is quoted and P69721-1A1 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Rank and voltage confirmed
We check rank, voltage and module type against the platform before quoting, which is where most memory orders go wrong.
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 P69721-1A1 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 P69721-1A1 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.
