The MTC40F2046S1RC56BD1 is Micron’s 64GB DDR5 ECC Registered DIMM operating at 5600 MT/s, a high-volume SKU for B2B buyers provisioning enterprise servers, data center rollouts, cloud infrastructure and virtualization platforms. We supply this part to resellers, system integrators and IT procurement teams in bulk quantities, with stock availability confirmed at time of order and batch consistency maintained across shipments so matched deployments can be deployed without mixing production lots.
As a JEDEC-standard DDR5 RDIMM, this module is intended for high-density server memory populations requiring registered signalling and ECC. Buyers should note that DDR5 RDIMMs are not backward-compatible with DDR4 or UDIMM platforms — integrators are advised to validate CPU and motherboard QVL support, including 5600 MT/s training behavior, prior to placing volume orders. Our technical sales team can assist with platform compatibility checks for project bids and tender submissions.

Sourcing & Integration Guidance for B2B Buyers
- Batch consistency: bulk orders are fulfilled from single production lots wherever possible, simplifying memory training validation and streamlining RMA handling for integrators building matched multi-module configurations.
- Platform validation: confirm the host platform’s memory Qualified Vendor List (QVL) and 5600 MT/s support — many server platforms will train the module down to a lower supported speed without issue.
- Configuration planning: the dual-rank (2Rx4) 64GB design offers a strong balance of capacity and channel population flexibility for virtualization and cache-tier workloads; verify CPU rank-per-channel limits for fully populated nodes.
- Warranty & RMA: modules are covered by manufacturer warranty with structured RMA processing through our wholesale channel; defective units within the RMA window are replaced or credited per agreed terms.
- Export compliance: shipments are provided with CE/FCC/RoHS-compliant documentation suitable for overseas distribution and customs clearance.
