Product overview
Part number 641231-001 identifies this HP 2GB RDIMM 240-Pin Memory Module. Memory is the part most often ordered wrong, because rank, voltage and population rules differ per platform and per slot. 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
The order is placed against 641231-001, not against a description of it, so there is no room for a substitution you did not agree to.
Rank and voltage confirmed
We check rank, voltage and module type against the platform before quoting, which is where most memory orders go wrong.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Questions buyers ask about this part
Is 641231-001 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 641231-001 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.
