The Samsung M393A4K40BB0-CPB is a 32GB DDR4-2133 registered ECC DIMM (RDIMM) addressing enterprise server, data center, virtualization and storage platforms. For IT procurement teams and system integrators, this module is a dependable capacity-oriented component for maintaining and extending DDR4-generation fleets — an entry speed grade (PC4-17000R) chosen for dependable bulk deployment rather than latency-sensitive cache workloads. As a wholesale item, it is offered in volume quantities suitable for reseller inventory and large-scale refresh projects.
Product Overview for Resellers & Integrators
We stock this Samsung RDIMM for ongoing B2B supply, with batch consistency maintained across shipments so integrators can populate multi-socket servers with uniform modules from the same production lot. Each order is verified by model number and speed grade (PC4-17000R) prior to dispatch to minimize mismatches against your platform’s qualified vendor list.

Procurement Guidance
- Platform compatibility: As a DDR4 RDIMM, this module is not backward-compatible with DDR3 or forward-compatible with DDR5 systems. Confirm that target servers validate RDIMMs at 2133 MT/s; mixing RDIMMs with LRDIMMs or UDIMMs in the same channel is not supported. Integrators should follow vendor population guidelines for balanced channel filling on multi-socket hosts.
- Batch consistency: Volume orders are fulfilled from matched lots wherever stock allows, ensuring identical firmware revision and rank configuration across the deployment — critical for uniform channel population and simplified RMA tracing.
- Warranty & RMA: All units ship with a standard B2B warranty covering manufacturing defects. RMA requests are processed through a defined procedure with traceable serial numbers; dead-on-arrival units are prioritized for replacement to protect your project timelines.
- Export & compliance: Shipments are prepared with CE, FCC and RoHS conformity documentation to support import clearance in most destination markets. Buyers are responsible for confirming local regulatory requirements.
- Family positioning: Within Samsung’s DDR4 RDIMM lineup, this 2133 MT/s CL15 dual-rank module represents the entry speed grade — commonly requested for capacity refreshes on older-generation platforms, while newer systems typically run higher-speed DDR4 RDIMMs.
