What you get ordering this from us
Ordered by part number
MTC40F2047S1RC56BB1 is what is quoted and MTC40F2047S1RC56BB1 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Population mapped for you
Send the current DIMM layout and we return the slot map with the quote, so the modules go in the right order.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Questions buyers ask about this part
Is MTC40F2047S1RC56BB1 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 MTC40F2047S1RC56BB1 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.
