Product overview
Part number MTC40F2046S1RC64B identifies this Micron 64GB DDR5 6400MHz ECC RDIMM Memory Module. Memory is the part most often ordered wrong — this is DDR5, 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.
We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.

Questions buyers ask about this part
- Is MTC40F2046S1RC64B genuine and is the warranty intact?
- Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
- Will MTC40F2046S1RC64B work in my server?
- Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.
