Samsung M386A8K40BMB-CRC

Overview

The Samsung M386A8K40BMB-CRC is a 64GB DDR4-2400 ECC server memory module designed to deliver high capacity and reliable performance for demanding server environments. Operating at 2400 megatransfers per second, it supports error correction code (ECC) to detect and fix bit errors, ensuring system stability for virtual machines, databases, and analytics workloads. Its Load Reduced DIMM (LRDIMM) design helps maintain signal integrity and throughput even when multiple modules are installed per channel.

Key features

• Load Reduced DIMM architecture with a register and on-board data buffer to reduce electrical load and improve signal quality
• Error correction code (ECC) technology that detects and corrects single-bit errors to prevent data corruption
• Four-rank x4 organization that maximizes memory capacity per slot for efficient use of server motherboard space
• Operates at a low voltage of 1.2 volts to reduce power consumption and heat generation in dense server racks
• Compatible with standard 288-pin DDR4 server sockets for easy integration into existing systems
• Enables building large memory pools by combining multiple modules, supporting high-performance computing and virtualization needs

Connectivity and compatibility

This memory module fits into standard DDR4 server sockets with a 288-pin layout, making it compatible with a wide range of server motherboards that support DDR4 ECC memory. Its design supports configurations with multiple DIMMs per channel, which is essential for scaling memory capacity in enterprise servers and high-performance computing systems.

Performance and reliability

By incorporating ECC technology, this module actively prevents data errors that could cause system crashes or data loss, which is critical for servers running mission-critical applications. The Load Reduced DIMM design reduces electrical load on the memory channel, allowing stable operation even when multiple modules are installed, which helps maintain consistent throughput and system responsiveness under heavy workloads.

Ideal uses and environments

This 64GB DDR4 ECC module is well suited for data centers, virtualization hosts, in-memory databases, and high-performance computing nodes where large memory capacity and error-free operation are essential. It supports administrators who need to expand memory without occupying every slot, enabling efficient scaling of memory pools to meet demanding application requirements.

Orders are processed within 2 business days, which includes verification, packing, and dispatch. Shipping costs are calculated at checkout based on destination, total weight, and selected speed. Free shipping applies to carts over $100 (excluding heavyweight items). All available options and final pricing are clearly shown before payment so you can choose the service that best fits your needs.

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.
