Samsung 16GB DDR4 2133 Mbps Server Memory Module

The Samsung M393A2G40EB1-CPB is a 16GB DDR4 Registered DIMM created for servers that need dependable memory capacity and consistent performance.

Operating at 2133 Mbps through a 288-pin interface, the module moves data quickly enough for everyday virtualization, database work, and high-traffic web services. A built-in register sits between the memory controller and the DRAM chips, smoothing clock, command, and control signals so the memory bus remains stable even when both DIMM slots per channel are populated.

Integrated error correction with 8-bit parity continuously checks and repairs single-bit faults, safeguarding workloads that cannot afford data corruption or unexpected downtime. Because the module runs at only 1.2 volts, it also helps keep power consumption in check across always-on racks.

The 2R x 4 layout uses two ranks per module, a common design in 2DPC server motherboards. Administrators can add this 16GB stick to compatible DDR4 slots to increase capacity without needing special tools or complicated setups, making it a practical upgrade for small business servers, edge appliances, and enterprise clusters that rely on stable, ECC-protected memory.

Highlights:

• 16GB DDR4 Registered DIMM rated at 2133 Mbps
• Integrated register steadies clock, command, and control signals
• ECC with 8-bit parity protects data from bit errors
• 2R x 4 organization designed for two-DIMMs-per-channel configurations
• Runs at 1.2 volts and connects through a 288-pin interface
