Samsung 8GB 2RX8 PC3-14900R Memory Module

Overview

The Samsung M393B1G73QH0-CMA is an 8GB DDR3 registered memory module designed for enterprise servers that require stable and consistent performance. It operates at speeds up to 1866 megatransfers per second and supports both 1.5 volts and a lower 1.35 volts, making it suitable for energy-conscious data centers and mixed-voltage environments. This module’s two-rank x8 architecture and 240-pin RDIMM form factor ensure compatibility with a wide range of server hardware.

Key features

• Registered design with an integrated register that manages clock, command, and signal timing for reliable operation under heavy workloads
• 8-bit error-correcting code (ECC) parity path to maintain data integrity and reduce the risk of errors in critical applications
• Dual voltage support (1.5 V and 1.35 V) to lower power consumption and heat generation in dense server racks
• Supports up to two DIMMs per channel in a 2DPC configuration, allowing flexible memory scaling without compromising stability
• 240-pin form factor that fits standard RDIMM slots, simplifying upgrades and replacements in existing server setups

Connectivity and compatibility

This memory module is designed to fit into standard 240-pin RDIMM slots commonly found in enterprise-grade servers. Its registered architecture and ECC support make it compatible with server platforms that require high reliability and error correction, such as virtualization hosts and database servers. The dual voltage operation allows it to integrate smoothly into systems with mixed power requirements, enhancing flexibility in large-scale deployments.

Performance and reliability

With a dedicated register controlling timing signals and an 8-bit ECC parity path, this module ensures data accuracy and signal integrity even under demanding workloads. Its ability to operate at a high data rate of 1866 MT/s supports fast data processing, which is essential for applications handling large datasets continuously. The option to run at a lower voltage reduces power consumption and thermal output, contributing to longer hardware lifespan and lower operational costs.

Ideal uses and environments

This Samsung memory module is well suited to enterprise environments that require dependable server memory, such as virtualization platforms, database management systems, and high-availability computing clusters. It fits well in blade chassis and rack servers where memory density and power efficiency are critical. IT professionals looking to expand memory capacity without sacrificing stability will find this module a practical choice for upgrading or maintaining their server infrastructure.
