The Samsung M393A2K43EB3-CWEBY is a 16GB DDR4-3200 dual-rank registered DIMM (2Rx8 RDIMM) designed for high-density enterprise server environments. Operating at standard 1.2V with CL22 timing, this module delivers reliable throughput of up to 25.6 GB/s while maintaining data integrity via onboard ECC and registering clock driver circuitry.
The Samsung M393A2K43EB3-CWEBY is architected as an enterprise-grade DDR4 Registered DIMM utilizing Samsung's 8Gb E-die DRAM components. It features a dual-rank organization with an x8 chip configuration (2Rx8), totaling 18 discrete FBGA packages across the module (16 for 128-bit payload data and 2 for parity/ECC overhead). The module integrates an onboard Registering Clock Driver (RCD) to re-drive command, address, and clock signals, significantly reducing the capacitive load on the host processor's memory bus and enabling greater DIMM population per channel.
The part number decodes deterministically: 'M393' denotes a Samsung RDIMM; 'A' signifies DDR4 technology; '2K' indicates a 16GB dual-rank layout; '43' defines x8 data organization; 'E' designates Samsung E-die generation; 'B' specifies the flip-chip BGA package and environmental standards; and '-CWE' indicates the JEDEC speed grade of DDR4-3200 with 22-22-22 timings at 1.2V. Sideband management is governed via standard I2C/SMBus through an integrated EEPROM Serial Presence Detect (SPD) device with thermal sensor.
Always verify against your server's qualified vendor list (QVL).
No. Mixing x8 RDIMMs with x4 RDIMMs within the same memory channel is unsupported by enterprise memory controllers, and mixing RDIMMs with LRDIMMs or unbuffered DIMMs is strictly unsupported across the entire system.
A 2Rx8 RDIMM uses fewer, wider-bus DRAM dies, lowering manufacturing costs for 16GB modules. However, 2Rx4 modules permit full multi-device Chipkill/Advanced ECC fault recovery, whereas 2Rx8 modules typically allow standard single-bit correction and double-bit detection (SEC-DED).
Yes. The JEDEC-compliant module natively supports legacy clock profiles through SPD fallback, allowing it to seamlessly run at 2933 MT/s, 2666 MT/s, or lower depending on the server CPU and population rules.
