The Samsung M393A2K43DB3-CWE is a 16GB DDR4 ECC registered DIMM (RDIMM) operating at 3200 MT/s, positioned in our wholesale catalog as a high-turnover SKU for resellers, system integrators, and IT procurement departments building out enterprise server deployments, data center projects, cloud infrastructure, virtualization environments, and HPC clusters. The module follows the JEDEC-defined 288-pin RDIMM specification on a 1.2V DDR4 platform profile, making it a reliable line item for repeat orders across memory-dense server configurations. Please note for your customer advisory: RDIMMs are compatible with DDR4 server platforms only and cannot be used in DDR5, UDIMM, or SODIMM slots — we recommend communicating this clearly downstream to reduce RMA friction from mis-purchasing.

Supply & Channel Considerations
- Stock availability: This SKU is stocked in volume with ongoing replenishment; current on-hand quantities and incoming stock schedules can be confirmed via our sales desk before you commit to project timelines.
- Batch consistency: We ship single-batch, date-code-matched lots per order wherever possible — important for integrators populating multi-channel servers and for resellers maintaining uniform inventory. Mixed date codes, when unavoidable, are disclosed before dispatch.
- Warranty & RMA: All modules carry a standard channel warranty with a defined RMA window; DOA units are prioritized for cross-ship to minimize downtime on your deployments.
- Lead times: In-stock orders typically ship within 1–3 business days; larger project quantities may require confirmation of allocation and a quoted lead time.
- Export compliance: Shipments are accompanied by CE, FCC, and RoHS conformity documentation to support your import clearance and enterprise tender requirements.
- Compatibility note for your customers: verify platform support for DDR4 RDIMMs and the maximum supported speed tier — the effective data rate is determined by the platform and runs at the lowest common speed of CPU and memory. Do not mix with LRDIMMs, DDR5 modules, or unregistered desktop memory.
- Deployment guidance: for expansion of existing installations, we recommend sourcing matching model numbers to keep vendor and date-code uniformity across the installed base; follow the server vendor’s channel population rules for balanced bandwidth.
