About the Micron 32GB DDR5-4800 RDIMM 1Rx4 CL40
CL40 at 1.1V — this Micron 32GB DDR5-4800 RDIMM delivers the low latency and tight power envelope that high-frequency trading platforms and in-memory databases demand. The MTC20F1045S1RC48BR combines single-rank, x4 organization with on-die ECC (ODECC) plus system-level error correction, making it production-ready for mission-critical enterprise infrastructure. Built on Micron's advanced 1-alpha nm process, this module supports Intel Xeon Scalable (Sapphire Rapids and newer) and AMD EPYC (Genoa and newer) DDR5 platforms without compromise.
The 1Rx4 configuration optimizes memory density while maintaining signal integrity across 288-pin JEDEC DDR5 standard form factor. Command/Address Parity, Post Package Repair (PPR), and Patrol Scrub compatibility ensure data resilience in 24/7 server environments. Storage architects and data center IT procurement teams standardizing on next-generation Xeon or EPYC infrastructure will find this module essential for workloads where both speed and reliability matter.

Deployment Scenarios
- High-frequency trading and algorithmic execution platforms requiring sub-nanosecond memory latency
- In-memory databases (Redis, Memcached) and real-time analytics on Xeon or EPYC clusters
- Machine learning inference pipelines where batch processing speed is cost-critical
- Financial risk modeling and Monte Carlo simulations needing consistent, low-latency access patterns
- Enterprise virtualization and consolidation with per-VM memory guarantees and ECC protection
