Samsung M393A4G40BB3-CWE 32GB DDR4-3200 RDIMM ECC Memory

Overview :

The Samsung M393A4G40BB3-CWE is a server-grade registered memory module engineered for enterprise and data-center platforms requiring high reliability and performance. It implements DDR4 SDRAM at 3200 MT/s with ECC and registered buffering to ensure signal integrity and error correction under heavy workloads.

Designed for dual-socket and multi-processor servers, this RDIMM delivers 32 GB capacity in a single-rank x4 configuration with a 288-pin form factor. The registered architecture offloads command/address signals through a register to improve stability in large memory configurations, making it suitable for virtualization, databases, and mission-critical compute clusters.

Deployment is typical in rack-mounted servers and enterprise systems that explicitly support DDR4-3200 RDIMMs with ECC. It is not suitable for consumer desktops or systems that require unbuffered UDIMM modules.

Key Features :

• 32 GB DDR4-3200 memory for heavy server workloads
• Registered DIMM enhances signal stability in multi-module systems
• ECC corrects single-bit errors for data integrity
• Single-rank x4 optimizes density and platform compatibility
• 1.2 V operation reduces power draw vs legacy DDR4 modules
