Samsung M393B1K70DH0-CH9

Overview

The Samsung M393B1K70DH0-CH9 is an 8 GB DDR3L Registered ECC memory module designed specifically for servers that require reliable data integrity and consistent performance. It operates at a transfer rate of 1333 MT/s and supports dual voltage modes of 1.5 V and 1.35 V, allowing data centers to optimize power consumption without sacrificing speed. This module is ideal for environments where stability and error correction are critical, such as virtualization hosts, database servers, and web application clusters.

Key features

• Built-in error-correcting code (ECC) with 8-bit parity detects and corrects common memory errors to maintain system stability.
• Onboard register improves timing for clock, command, and control signals, enhancing signal integrity when multiple modules share a memory channel.
• Dual-rank (2R × 4) configuration increases memory density per slot, maximizing capacity in server systems.
• Supports both 1.5 V and lower 1.35 V operation, helping to reduce power consumption and heat generation in data centers.
• 240-pin RDIMM format ensures compatibility with a wide range of industry-standard server motherboards.
• Designed to maintain performance and reliability under sustained, memory-intensive workloads common in enterprise environments.

Key specs

• Memory capacity: 8 GB
• Memory type: DDR3L Registered ECC
• Transfer rate: 1333 MT/s
• Voltage: 1.5 V / 1.35 V dual mode
• Module configuration: 2R × 4 (two ranks)
• Pin count: 240-pin RDIMM

Connectivity and compatibility

This memory module fits standard 240-pin RDIMM slots found in many dual-socket and quad-socket server motherboards. Its registered design and ECC support make it compatible with server platforms that require error correction and signal integrity for multi-module configurations. It is well suited for on-premises racks, blade chassis, and edge or branch servers where uptime is essential.

Ideal uses and environments

The Samsung M393B1K70DH0-CH9 is a strong choice for IT professionals managing virtualization hosts, database servers, or web application clusters that demand consistent memory performance and error-free operation. It works well in data centers aiming to balance power efficiency with throughput, as well as in remote or branch office servers where reliability is critical. This module provides a practical upgrade path for expanding memory capacity without replacing existing infrastructure.

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.
