Product overview
The Lenovo 64GB TruDDR5 6400MHz RDIMM is supplied under part number 4X77A90966. Memory is the part most often ordered wrong, because rank, voltage and population rules differ per platform and per slot.

Questions buyers ask about this part
Is 4X77A90966 genuine and is the warranty intact?
Yes. It ships new in Lenovo 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 4X77A90966 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.
