Samsung 4GB PC3-12800R DDR3-1600MHz DIMM Memory Module

Overview

The Samsung M393B5270DH0-CK0 is a 4GB registered DDR3 memory module designed for server environments where stability and data integrity are essential. Operating at 1600MHz, it delivers consistent performance while incorporating error-correcting code (ECC) with an 8-bit parity signal to automatically detect and correct memory errors. This module is built to support demanding workloads and maintain uptime in critical systems.

With a 240-pin layout and support for both 1.5V and 1.35V operation, it offers flexibility for various server configurations. Its registered design improves signal integrity by managing clock, command, and control signals, making it ideal for systems running multiple memory modules simultaneously.

Key features

• Registered DDR3 DIMM that enhances system stability by buffering control signals
• Error-correcting code (ECC) with 8-bit parity to maintain data accuracy and reduce system crashes
• Dual voltage support (1.5V and 1.35V) for compatibility with different server power requirements
• Supports x4 and x8 memory organizations and up to two ranks per DIMM for efficient memory expansion
• 240-pin form factor compatible with standard server motherboards

These features ensure reliable operation in server and workstation environments where memory errors can cause costly downtime or data loss.
