Micron MTC40F2047S1RC64B DDR5 RDIMM 128GB 6400MHz CL52 Server Memory

Overview

The Micron MTC40F2047S1RC64B is a 128GB DDR5 Registered DIMM (RDIMM) module, operating at 6400 MT/s with a CL52 latency. This memory is designed for server and workstation platforms that require high-capacity, high-speed RAM for demanding applications such as large-scale data analytics, virtualization, and high-performance computing. Its 32 Gbit density per rank ensures maximum capacity within a single module, reducing the number of DIMMs needed and potentially improving system stability and power efficiency. This specific tray configuration is ideal for bulk deployments where multiple identical modules are required.

Compatibility

This DDR5 RDIMM module is compatible with server and workstation motherboards and CPUs that specifically support DDR5 RDIMM memory, such as certain Intel Xeon Scalable processors (4th Gen 'Sapphire Rapids' and later) and AMD EPYC processors (Genoa/Bergamo and later). Always verify your motherboard's Qualified Vendor List (QVL) and CPU specifications for DDR5 RDIMM support, including maximum capacity per DIMM and total system memory. It is not compatible with DDR4 or DDR5 UDIMM slots.

Installation Notes

Install this module into a DDR5 RDIMM slot, ensuring correct orientation. Consult your system's motherboard manual for specific DIMM population guidelines, including channel interleaving and rank configuration for optimal performance. Ensure the system is powered off and grounded before installation. For optimal performance, populate memory channels evenly. The 6400 MT/s speed requires a CPU and motherboard chipset that supports this frequency; otherwise, the module will operate at the highest supported speed.
