The MTC40F2046S1RC64BD2 is Micron’s 64GB DDR5 ECC RDIMM operating at 6400 MT/s, a part we supply in volume to resellers, system integrators, and IT procurement teams building enterprise server platforms, AI compute clusters, and HPC deployments. As a registered DDR5 module with ECC, it is positioned for server SKUs where per-socket capacity and data integrity are procurement priorities. We maintain stock in consistent, single-batch allocations wherever possible, which simplifies channel-matched deployments and reduces cross-shipment variance for integrators. Buyers should note that DDR5 RDIMMs are neither backward nor forward compatible with DDR4 platforms; we recommend verifying that the target motherboard or server QVL lists this module or an equivalent DDR5 RDIMM before placing a purchase order.

Supply & Channel Notes
- ECC RDIMM form factor restricts use to server and workstation platforms that support registered DDR5 memory; the module will not function in consumer desktop boards designed for UDIMMs, and DDR5 cannot be combined with DDR4 regardless of physical fit — an important point when quoting end-customers to avoid RMA disputes.
- Within Micron’s DDR5 RDIMM lineup, this is the dual-rank (2Rx4) 64GB variant at 6400 MT/s; dual-rank modules generally interleave better under heavy memory pressure than single-rank equivalents, making them a strong fit for virtualization hosts and cache-tier workloads commonly specified by integrators.
- For maximum effective bandwidth on a given CPU, populate all supported memory channels with matched modules of the same speed grade and rank configuration. Mixed population can force the platform to a lower data rate, so confirm channel population rules in the server’s memory configuration guide before fulfilling mixed-configuration orders.
- All shipments are packaged in manufacturer-standard or equivalent anti-static trays to protect modules in transit and simplify staging for integration work.
- Products conform to CE, FCC, and RoHS requirements for export; documentation can be provided on request for customs and compliance review.
- Warranty and RMA handling is coordinated through our wholesale channel with a defined inspection window, keeping after-sales support manageable for resellers.
Wholesale & Procurement Notes
