32GB DDR5-4800 ECC Registered DIMM, 2Rx8, 288-pin, 1.1 V
The Micron MTC20F2085S1RC48BA1 is a 32GB dual-rank x8 DDR5 RDIMM (PC5-38400R), a common configuration in Intel Xeon Scalable 4th Gen and AMD EPYC 9004 servers. It is now listed as obsolete at distribution with authorized stock at zero, which makes like-for-like replacements for installed fleets harder to secure. Cerametronics supports buyers with traceable market stock and last-time-buy planning.

FAQ
What is the difference between MTC20F2085S1RC48BA1 and MTC40F2046S1RC48BA1?
Both are DDR5-4800 RDIMMs. MTC20F2085S1RC48BA1 is 32GB dual-rank x8; MTC40F2046S1RC48BA1 is 64GB dual-rank x4. They are not interchangeable in a qualified configuration.
Can I mix it with DDR5-5600 modules?
Mixed speeds normally run at the slowest module speed, but server OEMs qualify specific part numbers; keep the same part number within a channel where possible.
