The Samsung M393AAG40M32-CAE is a 128GB DDR4-3200 registered ECC DIMM (RDIMM) supplied through our B2B wholesale channel for resellers, system integrators, and IT procurement teams sourcing memory for server builds, virtualization clusters, and cloud or AI compute infrastructure. Built on 3DS stacked-die DRAM in a quad-rank configuration, it delivers maximum capacity per slot for high-density deployments. Buyers should note that as a DDR4 RDIMM it is not interchangeable with DDR5 or unbuffered desktop modules on the same platform.

Stock & Supply
Stock is held in batch quantities suitable for project rollouts and repeat reseller orders. We prioritize batch consistency: bulk orders are fulfilled from a single date code and manufacturing lot wherever possible, which simplifies qualification for system integrators and keeps channel populations uniform across multi-node builds. Confirm current inventory and batch availability before committing to delivery schedules.
Compatibility & Deployment Guidance
- Platform dependent: verify that the target server (e.g., Intel Xeon Scalable or AMD EPYC Gen 1/2/3 platforms) supports 128GB quad-rank RDIMMs and check the OEM’s validated memory list prior to volume ordering.
- Quad-rank 128GB modules reach large memory footprints while occupying fewer DIMM slots; note that per-channel maximum speed may be limited under certain population rules.
- For multi-channel servers, order matched modules (same part number and rank) in full kits to keep channels balanced and prevent memory training issues at boot.
Warranty & RMA
All units ship with a standard supplier warranty covering manufacturing defects. RMA requests are handled through our B2B support channel with defined turnaround targets; serial numbers and batch codes are logged per shipment to speed verification and replacement processing for wholesale customers.
Compliance & Export
Shipments are prepared with CE, FCC, and RoHS documentation available on request. As an overseas-facing wholesale operation, we support standard export documentation for cross-border procurement; buyers are responsible for confirming import eligibility in the destination market.
