The Samsung M393A2K43EB3-CWE is a 16GB DDR4-3200 registered ECC module positioned for volume procurement by resellers, system integrators, and corporate IT purchasing teams. It is a staple SKU for server builds, virtualization hosts, storage nodes, and cache-tier workloads where ECC-protected registered operation is mandatory. We stock this part for overseas wholesale distribution with consistent batch sourcing, supporting both single-project fulfillment and recurring supply agreements.
Procurement teams should note that RDIMMs are only deployable in server platforms that explicitly support registered DDR4 memory; they cannot be interchanged with unbuffered desktop modules, DDR5, or LRDIMM parts. For multi-unit deployments, we recommend sourcing modules with identical part numbers and rank configuration per server, which is why we emphasize batch consistency and single-datecode allocation on volume orders.

Supply & Channel Information
Stock & Batch Consistency
Inventory levels are updated regularly and confirmed at quotation stage. For orders above standard allocation, we can reserve stock and match datecodes across the shipment so that integrators receive modules from a single production batch—reducing qualification effort and mixed-batch risk in rack-scale rollouts.
Quality, Warranty & RMA
All modules ship as original Samsung product with full traceability. Units are covered by a standard wholesale warranty against manufacturing defects, with an RMA process handled directly by our export sales team. Defective units reported within the RMA window are replaced or credited according to the agreed terms, minimizing downtime for your downstream customers.
Compliance & Export
Shipments are packed for international freight and comply with CE, FCC, and RoHS requirements, with documentation available on request for customs clearance and end-customer audit purposes. Our export team is familiar with destination-market declaration requirements for IT components and can support branded invoicing and neutral packing where needed.
Who Should Buy
- Resellers and distributors seeking a high-turn enterprise memory SKU with dependable supply and margin support on volume commitments.
- System integrators building servers, virtualization clusters, or storage appliances that require matched-rank RDIMM sets at consistent datecodes.
- IT procurement departments standardizing on a single DDR4-3200 RDIMM capacity point across fleet refresh or maintenance projects.
Before ordering, confirm that your target platform supports DDR4 RDIMM operation at 3200 MT/s; note that some CPU and board combinations downclock modules depending on slots populated per channel. For pricing tiers, current stock, and lead-time confirmation on this SKU, request a wholesale quote from our export sales team.
