What is the memory capacity of the Micron MTC20F1045S1RC64BH1R module?

The Micron MTC20F1045S1RC64BH1R is a 32GB DDR5 registered DIMM. It uses a 4Gb x 80 ECC configuration, which provides 32GB of total capacity in a single module. This capacity can be combined with additional 32GB RDIMMs to achieve higher overall memory in compatible servers and workstations.

Which memory technology and speed does this module support?

This module is based on DDR5 RDIMM technology and is categorized as DDR5 6400, meaning it operates at 6400 mega transfers per second. It uses CL52 CAS latency at this speed, aligning with PC5 6400 performance specifications. These characteristics should match platforms that explicitly support DDR5 6400 RDIMM modules.

Does the Micron MTC20F1045S1RC64BH1R support ECC?

Yes, the Micron MTC20F1045S1RC64BH1R is an ECC registered module. The 4Gb x 80 organization indicates an x80 data layout with additional bits for error correction. As an ECC RDIMM, it is intended for systems that require error detection and correction, such as many servers and professional workstations.

What is the module organization and rank configuration?

The module uses a 1Rx4 configuration, making it a single rank RDIMM with x4 DRAM components. The Micron DDR5 RDIMM addendum describes it as 4Gb x 80 with 32 internal banks arranged in 8 groups of 4 banks. This organization is relevant for compatibility and performance behavior on supported platforms.

Which physical form factor does this DDR5 module use?

The Micron MTC20F1045S1RC64BH1R is a 288 pin DDR5 registered DIMM. This form factor is standard for DDR5 RDIMM modules and must match motherboards that provide 288 pin DDR5 RDIMM slots. The registered design includes a buffer for control signals as defined in Micron’s DDR5 RDIMM specifications.

What CAS latency is associated with this DDR5-6400 RDIMM?

For DDR5 6400 operation, Micron documents a CAS latency of CL52 with a clock period of approximately 0.312 nanoseconds at this data rate. This CL52 timing is one of the key parameters in the frequency and latency table for Micron DDR5 RDIMM modules running at 6400 mega transfers per second.

On what DRAM technology is this module based?

The module is based on 16Gb DDR5 SDRAM die components as referenced in Micron's DDR5 RDIMM documentation. These 16Gb devices are organized to create a 4Gb x 80 ECC layout on the 32GB module, consistent with the specifications in the Micron DDR5 RDIMM addendum and core data sheet.
