Samsung M393A4G43BB4-CWE

Overview

The Samsung M393A4G43BB4-CWE is a 32GB DDR4 registered DIMM designed specifically for server environments that require reliable and high-capacity memory. Operating at a data rate of 3200 Mbps with a low voltage of 1.2 volts, this module enhances data throughput while maintaining energy efficiency. Its architecture supports stable performance in densely populated server configurations, making it suitable for virtualization, database management, and compute-intensive tasks.

Key features

• Registered DIMM with integrated register buffers that maintain clean signal timing across multiple DIMMs on the same channel
• Error correcting code (ECC) that automatically detects and corrects single-bit memory errors to improve system stability
• 2R x 8 memory organization that balances capacity and performance for server workloads
• Compatible with dual-DIMM per channel RDIMM layouts, supporting high-density memory configurations
• Low power consumption at 1.2 volts, reducing heat output and energy costs in data centers

Key specs

• Capacity: 32 GB
• Memory type: DDR4 registered DIMM (RDIMM)
• Data rate: 3200 Mbps
• Voltage: 1.2 V
• Memory organization: 2R x 8
• Pin count: 288 pins
• Error correction: ECC (single-bit error correction)

Connectivity and compatibility

This memory module fits into standard 288-pin RDIMM slots found on modern server motherboards. It supports platforms that allow dual-DIMM per channel configurations, which is common in enterprise-grade servers and blade systems. The module’s register buffering ensures signal integrity even when multiple DIMMs share the same memory channel, making it a reliable choice for high-density server setups.

Installation and setup

Installing the Samsung M393A4G43BB4-CWE is straightforward. The module slots into compatible RDIMM memory sockets on server motherboards. After installation, administrators should verify memory population rules in the BIOS to ensure optimal configuration. Once recognized, the system can immediately utilize the expanded memory capacity to improve performance in demanding applications.

Ideal uses and environments

This 32GB DDR4 RDIMM is well suited to enterprise servers running virtualization hosts, database servers, and compute nodes that require large memory pools and high reliability. Its ECC capability and register buffering make it a strong choice for environments where uptime and data integrity are critical. It fits well in data centers aiming to maximize memory capacity without increasing power consumption significantly.

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.
