Product overview

Population order decides whether you get the full memory bandwidth or a fraction of it, and the rules change between one and two processors. This is a 4GB module.

Questions buyers ask about this part
Is 500658-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 500658-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.
