The Micron MTC40F204WS1RC48BB1 is a 96GB DDR5 ECC registered DIMM rated at 4800 MT/s, a stock item we supply in volume to resellers, system integrators, and IT procurement teams building out next-generation server, virtualization, cloud, and HPC environments. As an RDIMM, the registered interface supports higher module counts per channel, which makes it well suited for memory-dense server configurations where consistent, batch-matched modules are critical.
For B2B buyers, we focus on supply stability: current stock levels, single-batch allocation for matched orders, and full traceability on every shipment. Units are supplied in sealed original packaging with no consumer retailing involved, and all modules undergo incoming inspection before dispatch. Export-compliant documentation (CE, FCC, RoHS declarations) is available on request for customs and tender requirements.
Please note that DDR5 RDIMMs are not backward compatible — they cannot be combined with DDR4, UDIMM, or LRDIMM modules in the same system. We recommend confirming platform validation (1DPC/2DPC speed support) before placing volume orders; our sales team can assist with compatibility checks for common server platforms.

Procurement Guidance
- Platform compatibility: Requires a DDR5-capable server platform with RDIMM support. Do not mix with DDR4, UDIMM, or LRDIMM modules, and follow the vendor’s population guide for balanced channel deployment.
- Batch consistency for integrators: For large server builds, we allocate from a single manufacturing lot per order wherever possible, ensuring identical firmware, DRAM revision, and speed bin across all modules shipped.
- Deployment planning: The dual-rank 2Rx4 design using 24Gb DRAM reaches 96GB per module, allowing integrators to hit large memory footprints with fewer slots reserved — useful when quoting dense virtualization or cache-tier configurations.
- Warranty & RMA: All units carry the full Micron manufacturer warranty; our RMA desk handles advance-replacement and DOA claims for trade customers, minimizing downtime in your rollout schedule.
