Product overview
This is the HP Z400 Intel Xeon W3565 Processor 3.2GHz 6GB RAM 8MB L2 cache socket LGA1366 workstation, order code Z400-3. Registered, load-reduced and unbuffered modules are not interchangeable, and a board that accepts one will refuse to post on another.

Questions buyers ask about this part
- Is Z400-3 genuine and is the warranty intact?
- Yes. It ships new in HP 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 Z400-3 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.
