Product overview
This is the HP 32GB DDR4 2666MHz ECC RDIMM Memory Module, order code 815100-B21. Memory is the part most often ordered wrong, because rank, voltage and population rules differ per platform and per slot. This module is DDR4. Give us the server model and the DIMMs already fitted and we will confirm the configuration is supported.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

What you get ordering this from us
Ordered by part number
The order is placed against 815100-B21, 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 815100-B21 genuine and is the warranty intact?
Yes, new and sealed, with the HP warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will 815100-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, 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.
