SAMSUNG M393A2G40DB0-CPB 16GB DDR4 2133 RDIMM
The Samsung M393A2G40DB0-CPB is a 16GB DDR4-2133 ECC Registered DIMM (RDIMM) built for enterprise servers, data centers, virtualization platforms, and storage systems. It suits buyers maintaining or expanding DDR4-generation server fleets — virtualization hosts, storage controllers, and cache-tier workloads where ECC protection and registered signaling are mandatory. Note that DDR4 RDIMMs are not interchangeable with DDR5 modules: compatibility must be confirmed against your platform’s QVL before ordering.

Good to know
- As a registered DDR4 module, it can only be used in server/workstation platforms that support RDIMMs — it will not operate in consumer desktop boards and cannot be mixed with DDR5 or LRDIMM modules on the same channel.
- Within Samsung’s DDR4 RDIMM family, the 2133 MT/s PC4-17000R grade represents the entry speed tier; most DDR4 server platforms will accept it but will run all modules at the speed of the slowest installed DIMM.
- For multi-channel population, verify your board’s approved configurations in the vendor QVL and keep rank layout (2Rx4) consistent across channels for stable training — contact us for current stock and volume pricing.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
