The MTC40F2046S1RC56BD2 is Micron’s 64GB DDR5 ECC registered DIMM (RDIMM) rated at 5600 MT/s, positioned for wholesale distribution to resellers, system integrators and enterprise IT procurement teams deploying current-generation DDR5 server platforms. Stock is held in volume with batch-consistent supply, so multi-unit orders ship with matched manufacturing lots — critical for integrators populating mixed-channel servers where uniform SKUs simplify validation and reduce RMA risk. Please note this is a DDR5-only module: it is not compatible with DDR4 RDIMMs and buyers should confirm platform generation before placing purchase orders.

Procurement Guidelines
- This RDIMM requires a server platform with registered-DIMM support; it is not suitable for consumer desktop boards, and DDR5 RDIMMs cannot be mixed with DDR4 memory in any configuration. Integrators should verify platform generation across the full project BOM before ordering.
- The dual-rank (2Rx4) layout fills memory channels efficiently at high capacities, making it a preferred SKU for virtualization, caching and cloud node builds — advise end customers to follow their motherboard vendor’s population-order guide during deployment.
- On platforms rated below 5600 MT/s the module will downclock to the maximum supported rate. Resellers should cross-check the target system’s qualified vendor list (QVL) to avoid compatibility-related returns.
- All units ship from compliant stock with export documentation available; the product meets CE, FCC and RoHS requirements for international distribution.
- Standard warranty applies with structured RMA handling through our wholesale support channel; batch numbers are logged per shipment to enable lot-level traceability for enterprise deployments.
Wholesale & Procurement Notes
