Samsung M386A8K40BM1-CRC

Overview

The Samsung M386A8K40BM1-CRC is a 64GB DDR4 2400MHz PC4-19200 ECC Load Reduced DIMM memory module designed specifically for server environments. It operates at 1.2 volts and uses a 288-pin format, making it suitable for high-density memory configurations in enterprise servers and data centers. This module supports quad-rank x4 architecture and is optimized for setups with up to three DIMMs per channel, ensuring stable and reliable performance in demanding IT applications.

With built-in ECC functionality, it detects and corrects memory errors to maintain data integrity and reduce system crashes, which is essential for virtualization platforms and continuous server operation.

Connectivity and compatibility

This memory module is designed to fit standard 288-pin DIMM slots on server motherboards that support DDR4 ECC Load Reduced DIMMs. It is compatible with systems requiring high memory capacity and error correction, commonly found in data centers, enterprise servers, and virtualization platforms. Its quad-rank architecture and support for multiple DIMMs per channel make it a strong choice for dense memory configurations.

Performance and reliability

The module’s ECC capability ensures that memory errors are detected and corrected automatically, which is critical for maintaining uptime and data accuracy in professional server environments. The load reduced design buffers signals to reduce electrical load on the memory controller, allowing for higher memory density without sacrificing performance or stability. Operating at 2400 MHz, it delivers consistent speed suitable for demanding workloads.

Ideal uses and environments

This Samsung memory module fits well in enterprise-grade servers, data centers, and virtualization setups where large memory capacity and error-free operation are priorities. It is a strong option for IT professionals upgrading servers to handle intensive applications, databases, or virtual machines that require reliable and efficient memory performance over long periods.

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.
