Product overview
MTC20F1045S1RC56B is a Micron 32GB DDR5-5600 ECC registered RDIMM single rank x4 288-Pin Server Memory Module. 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 32GB module. Send the current layout and we will map the slots for you.
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 MTC20F1045S1RC56B 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 MTC20F1045S1RC56B 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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.
