Micron 96GB DDR5-6400 PC5-51200 ECC Registered DIMM — MTC40F204WS1RC64BC1

The Micron MTC40F204WS1RC64BC1 is a 96GB DDR5 ECC Registered DIMM (RDIMM) operating at 6400MHz (PC5-51200), manufactured by Micron Technology — one of the world’s leading DRAM producers. This high-capacity, high-speed module is designed for enterprise server platforms requiring maximum memory density and bandwidth. At 96GB per DIMM, it enables exceptional memory capacity per socket for memory-intensive workloads including AI/ML training, in-memory databases, virtualization, and high-performance computing. DDR5-6400 delivers significantly higher bandwidth than DDR5-4800 or DDR5-5600, making it ideal for next-generation server deployments on Intel Xeon Scalable 5th Gen (Emerald Rapids) and compatible platforms.

• Always verify compatibility with your specific server model’s memory QVL or memory configurator before ordering
• Suitable for AI/ML training and inference, in-memory databases (SAP HANA, Redis, VoltDB), virtualization, HPC, and data analytics workloads

Ordering Notes

• 96GB RDIMM — verify your server’s maximum supported DIMM capacity before ordering
• DDR5-6400 requires platform support — verify CPU and motherboard compatibility; may train at lower speeds on DDR5-4800 or DDR5-5600 platforms
• Mix only identical DIMMs (same part number, speed, rank, and manufacturer) within a memory channel for optimal stability
• For maximum memory bandwidth, populate all memory channels per CPU socket
