About the Micron DDR5 RDIMM 128GB 2Rx4 6400 CL52 ECC Server Memory
CL52 latency at 1.1 V operating voltage — this Micron DDR5 RDIMM delivers the low-latency, low-power profile essential for high-frequency trading, in-memory databases, and latency-sensitive analytics workloads. At DDR5-6400 speed (6400 MT/s), the MTC40F2047S1RC64BB1R achieves 128 GB capacity per module with a 2Rx4 rank configuration and 72-bit bus width (64-bit data plus 8-bit ECC protection). The module's CL52-52-52 primary latency specification, combined with on-die ECC per DRAM device and RDIMM bus-level ECC, provides both speed and data integrity for mission-critical server environments.
Built to JEDEC DDR5 RDIMM standard specifications, this Micron memory module features SPD5 (DDR5 Serial Presence Detect hub) auto-detection and an on-module I²C thermal sensor for real-time temperature monitoring. The 288-pin form factor and standard RDIMM height (31.25 mm) ensure broad compatibility with next-generation Intel Xeon Scalable 6 (Granite Rapids) and AMD EPYC 9005 (Turin) platforms. A single socket supports up to 1.536 TB capacity across 12 channels (12 × 128 GB). Storage architects and IT procurement teams seeking enterprise-grade registered memory for dense, high-performance compute clusters will find this module (part number MTC40F2047S1RC64BB1R) backed by Micron limited-lifetime support and available in stock through Omnixon Global.
Deployment Scenarios
- High-frequency trading and algorithmic finance platforms requiring sub-microsecond latency and ECC reliability
- In-memory databases (Redis, Memcached, SAP HANA) on Xeon Scalable 6 and EPYC 9005 infrastructure
- Real-time analytics and machine learning inference with strict data integrity requirements
- Dense virtualization and hyperconverged infrastructure leveraging 1.536 TB per-socket capacity
- Mission-critical enterprise applications where thermal monitoring and automatic error correction are non-negotiable
