Frequently Asked Questions
What is the difference between registered and unbuffered DDR3 memory?
Registered (buffered) DDR3 memory like the Samsung M393B5673GB0-CH9 includes a register that buffers the address and control signals, reducing electrical load on the memory controller. This design is essential for multi-socket servers and large-capacity memory configurations, providing greater stability and supporting higher memory densities than unbuffered alternatives.
Why is ECC memory important for server environments?
ECC (Error-Correcting Code) memory automatically detects and corrects single-bit errors that can occur due to cosmic radiation, electrical interference, or component degradation. For mission-critical applications, this DDR3 ECC module prevents data corruption, system crashes, and unplanned downtime—making it essential for data centers, virtualization, and financial systems.
Is the Samsung M393B5673GB0-CH9 compatible with my server?
The Samsung M393B5673GB0-CH9 is compatible with servers featuring 240-pin DIMM slots that support DDR3 1333MHz registered ECC memory. Verify your server's memory specifications in the documentation or contact your system administrator. This module is commonly used in enterprise-class systems from Dell, HP, IBM, and Lenovo.
What are the performance benefits of 1333MHz DDR3 memory?
Operating at 1333MHz, this DDR3 registered DIMM provides optimal balance between speed and power efficiency for server workloads. It delivers sufficient bandwidth for multi-core processors while maintaining thermal efficiency—ideal for virtualization, database operations, and high-availability computing environments.
