64GB DDR5-5600 ECC Registered DIMM, 2Rx4, 288-pin, 1.1 V
The Micron MTC40F2046S1RC56BD1 is a 64GB dual-rank x4 DDR5 RDIMM (PC5-44800R) used in Intel Xeon Scalable 5th Gen and AMD EPYC 9004 class servers. Distributors list this part number as end of life and authorized stock is at zero while AI and cloud build-outs absorb DDR5 capacity. Cerametronics supports buyers with traceable market stock and helps plan the move to current revisions.

FAQ
Will this module run in a DDR5-4800 server?
In most platforms it runs at the speed the platform supports (for example 4800 MT/s), but server OEMs qualify specific part numbers, so check the platform memory list.
What does the BD1 suffix indicate?
The suffix identifies the speed bin and module revision. Different revisions of the same capacity can be qualified separately by OEMs, so confirm the exact suffix your platform requires.
