Micron 1x 32GB DDR5-6400 RDIMM PC5-51200R Single Rank x4 Module
Product Overview
The MTC20F1045S1RC64BD2 is a 32 GB DDR5‑6400 ECC RDIMM, single‑rank ×4, 1.1 V module, tailored for high-throughput and reliability‑critical server environments. Its low-profile design and broad OEM compatibility make it a premium yet practical upgrade choice for 3rd and 4th generation high-end server platforms. Do check your server motherboard/BIOS compatibility (particularly with high-density RDIMMs), but otherwise this is a robust pick for memory-intensive workloads.
This RAM module also operates at a standard voltage of 1.1V with a CAS Latency of CL52, and is designed to allow you to run more applications simultaneously, switch between them faster, and provide a smoother computing experience.
