Samsung M393A1K43DB2-CWE

Overview

The Samsung M393A1K43DB2-CWE is an 8 GB DDR4 registered DIMM designed specifically for server environments, delivering reliable memory performance at speeds up to 3200 Mbps. Operating at a low voltage of 1.2 V, this module ensures efficient power consumption while maintaining signal integrity through its onboard register and error-correcting code support. Its 288-pin form factor fits standard server memory slots, making it a practical choice for expanding memory capacity in enterprise servers and high-performance computing clusters.

Key features

• Registered DIMM design that stabilizes clock, command, and control signals even in fully populated motherboards
• Error-correcting code (ECC) with an 8-bit parity layer to maintain data integrity during critical workloads
• 1R x 8 single-rank layout that supports predictable signal routing and effective cooling
• Low 1.2 V operation to reduce power consumption and heat generation in dense server setups
• Compatibility with x4 and x8 DRAM configurations for flexible system integration
• Supports two-DIMMs-per-channel configurations to increase memory density without sacrificing throughput
• Ideal for continuous operation environments such as virtualization hosts and database servers

Connectivity and compatibility

This memory module fits into standard 288-pin server DIMM slots and supports both x4 and x8 DRAM configurations, allowing it to work seamlessly with a wide range of server motherboards. Its registered design ensures stable operation in systems with multiple DIMMs installed per channel, which is common in enterprise-grade servers.

Performance and reliability

With ECC support and an onboard register, this module maintains clean signal transmission and corrects errors on the fly, which is essential for maintaining uptime and data accuracy in demanding server workloads. Its low voltage operation helps reduce thermal output, contributing to system stability and longevity in 24/7 operation scenarios.

Ideal uses and environments

This Samsung memory module is well suited for system administrators looking to expand memory capacity in rack or tower servers used for virtualization, database management, and high-performance computing. It fits well in environments where data integrity and continuous operation are critical, providing a balance of speed, capacity, and reliability for enterprise applications.

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.
