Product overview
Part number MTC40F2046S1RC56BG1 identifies this Micron 64GB DDR5-5600 ECC registered RDIMM dual rank x4 288-Pin Server Memory Module. Registered, load-reduced and unbuffered modules are not interchangeable, and a board that accepts one will refuse to post on another. This module is ECC. Send the server model and we will check it against the supported-DIMM list before you order.
Quotes are itemised down to the accessories, so nothing that is needed to make the part work is left off and discovered later.

Questions buyers ask about this part
- Is MTC40F2046S1RC56BG1 genuine and is the warranty intact?
- Yes. It ships new in Micron 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 MTC40F2046S1RC56BG1 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?
