Micron MTC40F2047S1RC80BF1R 128 GB DDR5-8000 ECC RDIMM

Increase installed server memory capacity with a 128 GB registered DDR5 module for systems that accept DDR5 ECC RDIMMs. The DDR5-8000 speed grade and PC5-68000 bandwidth class suit server memory configurations that support this data-rate class. Registered buffering and error-correcting code align with the memory-channel requirements of compatible server platforms, where high-capacity DIMMs are installed according to validated processor and motherboard population rules. Micron MTC40F2047S1RC80BF1R combines 128 GB capacity with a 2Rx4 organization and CL64 latency designation. Those characteristics are material when matching memory to a validated server configuration, particularly where every populated channel must use supported DIMM types, capacities, and speed grades. The module is supplied as a single unit, enabling capacity expansion in 128 GB increments while retaining the registered ECC architecture required by the host system. This configuration occupies a specific position within registered DDR5 memory: high density, an 8,000 MT/s transfer-rate grade, ECC support, and 2Rx4 organization in one RDIMM. Validate processor memory-controller support, installed firmware, available channels, and DIMM population rules before installation. It is registered server memory rather than unbuffered desktop memory, so it belongs in platforms explicitly engineered for DDR5 RDIMM operation.
