The Samsung M393A4K40DB3-CWE is a 32GB DDR4 ECC registered DIMM (RDIMM) operating at 3200 MT/s, positioned as a high-volume line item for resellers, system integrators, and IT procurement teams sourcing DDR4-generation server memory. As a trade channel, we supply this module in mixed lot sizes suitable for fleet refreshes, server builds, and data center expansions — from partial pallet quantities to container-level orders. Batch consistency is a priority: we endeavor to ship single date-code and single-revision lots per order wherever stock allows, which simplifies qualification testing and reduces mixed-batch risk on your integration floor. Note that RDIMMs are generation-specific — they cannot be combined with DDR5 or unbuffered desktop modules — so confirm your platform’s QVL before placing a volume order.

Stock, Warranty & Compliance
- Availability: This SKU is listed against our live wholesale inventory with regular stock reconciliation. Current on-hand quantity, incoming shipments, and reserve allocation are confirmed at quotation stage; large orders can be split into staged deliveries to match your project rollout schedule.
- Warranty & RMA: Modules ship with a standard channel warranty. Defective units are handled through a streamlined RMA process — buyers obtain an RMA number, ship consolidated returns, and receive tested replacements or credit. Serial numbers are logged per shipment to speed up claims processing for both resellers and integrators.
- Compatibility for integrators: As a 288-pin DDR4 RDIMM, this module fits DDR4 server platforms only (e.g., Intel Xeon Scalable or AMD EPYC generations supporting DDR4). It will not seat in DDR5 or desktop UDIMM slots, and RDIMMs should not be mixed with LRDIMMs in the same channel — a key check point when quoting multi-vendor fleet upgrades.
- Configuration consistency: The 1Rx4 single-rank layout leaves room for higher per-channel population and future capacity expansion. For tenders and mixed deployments, we recommend locking model number, speed grade (PC4-25600R), and rank configuration across all channels to avoid memory training or population-order issues.
- Export & certification: Shipments are prepared for cross-border B2B trade with standard export documentation. Product complies with applicable CE, FCC, and RoHS requirements for destination-market customs clearance and enterprise procurement audit trails.
