Samsung 2GB DDR3 1066 Mbps Server Memory Module

Overview

The Samsung M392B5773CH0-CF8 is a 2 GB DDR3 registered DIMM designed specifically for server environments that demand reliable memory performance and easy scalability. Operating at a data rate of 1066 Mbps, it provides sufficient bandwidth for rack-mounted file servers, virtualization hosts, and small business database systems. This module is ideal for upgrading existing DDR3 platforms or replacing older memory without altering the system architecture.

Its 1 R x 8 organization and onboard register help reduce the electrical load on the memory controller, which is especially beneficial in multi-slot configurations. The integrated error-correcting code (ECC) with 8-bit parity enhances system stability by detecting and correcting single-bit errors, minimizing the risk of unexpected downtime.

Key features

• Registered DIMM design buffers command and control signals to improve memory controller efficiency in multi-module setups
• Error-correcting code with 8-bit parity safeguards data integrity and reduces system crashes
• Dual-voltage operation at 1.5 V and 1.35 V supports both standard and low-power server platforms, helping reduce energy consumption
• 240-pin interface ensures compatibility with common DDR3 server sockets for straightforward installation
• Supports flexible memory configurations with up to two DIMMs per channel and two ranks per DIMM
• Component structure simplifies sourcing and matching for technicians managing blade systems or spare inventories
