Samsung 8GB DDR3 1066 Mbps Server Memory Module

Overview

The Samsung M393B1K73CH0-CF8 is an 8 GB DDR3 Registered DIMM memory module designed specifically for server environments that require reliable and consistent performance. Operating at a data rate of 1066 Mbps, it provides the bandwidth necessary for demanding applications such as virtual machine hosting, database management, and web services. This module supports both 1.5 V and a lower 1.35 V power mode, allowing for energy-efficient operation without compromising stability.

Key features

• Registered DIMM design shifts clock and control signals away from the memory controller to reduce electrical loading and improve signal integrity.
• ECC with an 8-bit parity layer automatically detects and corrects single-bit errors, helping to prevent system crashes and data corruption in critical workloads.
• Dual voltage operation at 1.5 V or 1.35 V offers flexibility to balance power consumption and performance across server racks.
• 4R × 8 rank structure enhances stability and compatibility in multi-DIMM configurations, including systems with two DIMMs per channel.
• Standard 240-pin interface ensures straightforward installation in most server motherboards.
• Chip layout of (256 M × 8) × 36 supports reliable operation in x4 or x8 memory configurations.
