Samsung M393A2K40EB3-CWE

Overview

The Samsung M393A2K40EB3-CWE is a 16 GB DDR4 registered DIMM designed to enhance server memory capacity with reliable, high-speed performance. Operating at 3200 MHz and using a low 1.2 V voltage, it delivers the bandwidth needed for demanding data workloads while maintaining energy efficiency. This module is tailored for servers with 288-pin RDIMM slots, providing stability and error correction essential for critical computing environments.

Key features

• Registered DIMM architecture buffers command and clock signals to reduce electrical loading and improve stability in systems with multiple memory modules.
• ECC with 8-bit parity automatically detects and corrects single-bit errors, ensuring data integrity during continuous operation.
• Single-rank x4 organization balances capacity and thermal performance, supporting configurations with two DIMMs per channel.
• JEDEC-compliant design ensures compatibility with a wide range of server platforms following industry standards.
• Low 1.2 V operating voltage helps reduce power consumption in dense server environments.
• CL22 latency timing aligns with server memory standards for consistent performance.

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.
