Samsung M393B4G70DM0-YH9

Overview

The Samsung M393B4G70DM0-YH9 is a 32 GB DDR3 registered DIMM designed specifically for server environments that demand reliable and high-capacity memory. With a data transfer rate of up to 1333 Mbps, it supports virtualization hosts, database nodes, and file servers by delivering fast and consistent performance. Its dual-voltage operation at 1.5 V or 1.35 V allows administrators to optimize power consumption without sacrificing speed, making it a versatile choice for various server configurations.

Key features

• Registered DIMM design buffers clock, command, and control signals to maintain signal integrity under heavy workloads
• Error correction with 8-bit parity detects and corrects single-bit errors, ensuring data integrity during critical operations
• Supports both x4 and x8 memory chip organizations, providing flexibility when mixing modules in multi-rank configurations
• Compatible with dual-DIMM-per-channel setups, enabling straightforward memory capacity expansion on multi-socket server boards
• Operates at two voltage levels (1.5 V and 1.35 V) to balance power efficiency and performance based on system requirements
• 4R x 4 rank structure enhances memory density while maintaining compatibility with a wide range of server platforms

Connectivity and compatibility

This memory module is designed to fit standard 240-pin DDR3 server slots and supports configurations common in enterprise-grade servers. Its registered design and error correction capabilities make it compatible with systems that require high reliability and uptime. The module’s support for dual-DIMM-per-channel setups allows it to integrate seamlessly into multi-socket server motherboards, facilitating scalable memory upgrades.

Performance and reliability

By buffering control signals through an onboard register, this module reduces electrical noise and timing issues, which helps maintain stable operation during intensive workloads. The 8-bit parity error correction actively protects against data corruption, a critical feature for servers handling sensitive or mission-critical information. Its ability to operate at lower voltage also contributes to reduced heat generation and power consumption, enhancing overall system efficiency.

Ideal uses and environments

This 32 GB DDR3 registered DIMM is well suited for data centers, virtualization servers, and database management systems where large memory capacity and data integrity are essential. It fits well in environments that require reliable memory performance over extended periods, such as enterprise IT infrastructures and engineering labs. The module’s flexibility in voltage and rank configuration makes it a strong choice for administrators looking to optimize both performance and power usage in their server setups.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
