SAMSUNG M393A2G40DB0-CPB 16GB DDR4 2133 RDIMM

SAMSUNG M393A2G40DB0-CPB 16GB DDR4 2133 RDIMM

SKU: 4879

The Samsung M393A2G40DB0-CPB is a 16GB DDR4-2133 ECC Registered DIMM (RDIMM) sourced for wholesale distribution to resellers, system integrators, and IT procurement teams servicing enterprise server fleets, data center refresh projects, virtualization platforms, and storage deployments. Because DDR4 RDIMMs are not interchangeable with DDR5 modules, we recommend buyers verify platform compatibility against the vendor QVL before committing order quantities.

For Resellers and System Integrators

This SKU is stocked in volume and shipped in consistent batches, which matters when fulfilling mixed-server rollouts or multi-unit integration projects where matched silicon across channels simplifies memory training and reduces RMA risk. Original packaging and manufacturer labeling are preserved for resale.

Units are covered by a standard wholesale warranty with structured RMA handling: defective returns are processed through our support desk with batch traceability, keeping your after-sales workload low. All shipments are accompanied by export-compliant documentation and the product meets CE, FCC, and RoHS requirements, making it suitable for cross-border distribution.

Typical allocation for this grade suits resale into maintenance contracts, spare-parts stocking, and DDR4-generation capacity upgrades for virtualization hosts, storage controllers, and cache-tier workloads where ECC protection and registered signaling are mandatory. Note that within the DDR4 RDIMM family, the 2133 MT/s PC4-17000R grade is the entry speed tier; most DDR4 server platforms will accept it but run all modules at the speed of the slowest installed DIMM. As a registered module it will not operate in consumer desktop boards and cannot be mixed with DDR5 or LRDIMM modules on the same channel.

For current stock levels, batch details, and volume pricing, please request a wholesale quote and our sourcing team will respond with an allocation plan tailored to your project timeline.
