Product overview
Part number P43333-1A1 identifies this HPE 64GB (1x64GB) dual rank x4 DDR5-4800 CAS-40-39-39 EC8 registered smart Memory (assembly # for option P50312-B21, ProLiant Gen11 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.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

What you get ordering this from us
Ordered by part number
P43333-1A1 is what is quoted and P43333-1A1 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
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 P43333-1A1 genuine and is the warranty intact?
- Yes — new and sealed, with the HPE warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will P43333-1A1 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. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

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.
