Samsung M393A4G40BB3-CWE

Overview

The Samsung M393A4G40BB3-CWE is a server memory module that delivers 32GB of DDR4 capacity with a data transfer rate of up to 3200 Mbps. Designed as a Registered DIMM (RDIMM), it includes an integrated register to stabilize clock, command, and control signals, which is essential when multiple modules are installed in the same system. This stability makes it a reliable choice for virtualization hosts, database servers, and other environments where memory density and uptime are critical.

Operating at a low voltage of 1.2 V, the module reduces power consumption and thermal output, which is beneficial in densely packed server racks. Its ECC support with an 8-bit parity scheme ensures that bit errors are detected and corrected automatically, maintaining data integrity in demanding applications. The single-rank x4 organization enhances compatibility with platforms that limit rank count per channel, while the 288-pin layout fits standard DDR4 server motherboards.

Key features

• Registered DIMM design that stabilizes signals for reliable multi-module operation
• Low 1.2 V operating voltage to reduce power consumption and heat generation
• ECC with 8-bit parity for automatic detection and correction of memory errors
• Single-rank x4 organization to support a wide range of server platforms
• Supports two DIMMs per channel configurations for easy scalability
• 288-pin form factor ensures compatibility with standard DDR4 server motherboards

Key specs

Compatibility and scalability

This memory module is designed to fit seamlessly into server motherboards that support DDR4 RDIMMs with a 288-pin layout. Its single-rank x4 organization makes it compatible with platforms that restrict the number of ranks per channel, allowing for flexible system configurations. The module supports two DIMMs per channel setups, which helps system builders scale memory capacity as workloads increase without compromising stability or performance.

Performance and reliability

With ECC support and an 8-bit parity scheme, this module ensures data integrity by detecting and correcting bit errors automatically. The registered design helps maintain signal integrity across multiple modules, which is crucial in high-density server environments. Operating at 3200 Mbps, it provides responsive memory performance suitable for demanding applications such as virtualization, database management, and high-performance computing.

Ideal uses and environments

The Samsung M393A4G40BB3-CWE is well suited to enterprise servers that require high memory capacity and reliability. It fits well in virtualization hosts, database servers, and computing clusters where uptime and data accuracy are paramount. Its low power consumption and thermal output also make it a practical choice for densely populated server racks, helping to maintain efficient cooling and energy use.

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.
