Samsung 32GB PC3-8500 DDR3-1066MHz ECC Registered Memory Module

Overview

The Samsung M393B4G70AM0-YF8 is a server memory module that provides 32 GB of DDR3 capacity with a PC3-8500 data rate running at 1066 MHz. It is designed to support demanding data workloads such as virtualization, database management, and other server applications that require fast and reliable memory performance. This module features error-correcting code (ECC) and a registered design to ensure data integrity and system stability in multi-DIMM configurations.

Key features

• ECC with 8-bit parity detects and corrects single-bit memory errors to prevent system crashes and data corruption.
• Registered DIMM includes an onboard register that buffers clock, command, and control signals, enhancing stability when multiple modules are installed.
• Dual-voltage operation at 1.35 V or 1.5 V allows for reduced power consumption and heat generation when supported by the server motherboard.
• Quad-rank x4 configuration supports high-density memory setups, making it suitable for servers requiring large memory footprints.
• Standard 240-pin form factor ensures compatibility with systems designed for registered ECC DDR3 memory modules.

Connectivity and compatibility

This memory module is designed for server platforms that support registered ECC DDR3 memory with a 240-pin DIMM slot. It fits well in enterprise-grade rack servers and workstations that require reliable, high-capacity memory to handle virtualization, large databases, and intensive data processing tasks. Compatibility depends on the server motherboard’s support for quad-rank modules and dual-voltage operation.

Performance and reliability

With ECC error correction and a registered design, this module maintains data integrity and system stability even under heavy workloads. The ability to operate at a lower voltage reduces power consumption and heat output, which contributes to longer component life and more efficient server operation. Its quad-rank configuration allows for higher memory density, supporting larger datasets and more virtual machines without compromising performance.

Ideal uses and environments

This Samsung memory module is a strong choice for data centers and IT environments that demand dependable, high-capacity memory solutions. It works well in virtualization hosts, database servers, and compute clusters where consistent memory performance and error correction are critical. Administrators looking to upgrade or expand server memory capacity will find this module meets the needs of modern enterprise workloads while offering power efficiency and stability.
