About the Micron 64GB DDR5-4800 RDIMM 2Rx4 CL40
A single 64GB Micron DDR5-4800 RDIMM unlocks up to 2TB of maximum server memory capacity per system — a critical ceiling for data center architects and infrastructure teams planning high-density compute environments. The MTC40F2046S1RC48BR delivers enterprise-grade reliability with registered memory architecture, dual-rank organization, and integrated on-die ECC (ODECC) to meet mission-critical uptime demands across virtualization, database, and AI workload clusters.
Micron's DDR5-4800 specification reaches 4800 MT/s throughput at CL40 latency, balancing bandwidth and responsiveness for latency-sensitive applications. Operating at just 1.1V, this module reduces power consumption compared to prior DDR4 generations, directly impacting total cost of ownership for large-scale deployments. Storage architects and IT procurement teams evaluating third-generation EPYC or Intel Xeon Scalable processors will recognize the SPD5 hub implementation and JEDEC DDR5 compliance as table-stakes for modern hyperscale infrastructure. Micron's proven track record in data center memory ensures compatibility and performance predictability across OEM and custom-built systems.
