Product overview
MTC40F2046S1RC64B is a Micron 64GB DDR5 6400MHz ECC RDIMM Memory Module. Memory is the part most often ordered wrong, because rank, voltage and population rules differ per platform and per slot. This module is DDR5. Give us the server model and the DIMMs already fitted and we will confirm the configuration is supported.
The listed price is per unit and current; tell us the quantity and we will confirm what it holds at before you raise the order.

Questions buyers ask about this part
Is MTC40F2046S1RC64B genuine and is the warranty intact?
Yes, new and sealed, with the Micron warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
Will MTC40F2046S1RC64B 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.
