Samsung M386A8K40BM2-CTD

Overview

The Samsung M386A8K40BM2-CTD is a 64GB DDR4 SDRAM memory module designed to enhance server and data center performance with reliable and efficient operation. Operating at 2666 Mbps and consuming just 1.2 volts, it balances speed and power efficiency for demanding computing environments such as cloud infrastructure and 5G connectivity systems. Its Load Reduced DIMM (LRDIMM) technology allows for higher memory densities by using a data buffer, which supports smooth and scalable performance in high-capacity setups.

Key features

• Load Reduced DIMM design that increases memory capacity and efficiency by reducing electrical load on the memory controller
• High-speed operation at 2666 Mbps to support fast data processing and reduce bottlenecks in server workloads
• Low voltage operation at 1.2V to minimize power consumption and heat generation in dense server environments
• Supports up to four ranks per DIMM, providing flexibility for scaling memory configurations
• Thoroughly tested for stability and compatibility to ensure reliable performance across various platforms
• 288-pin form factor designed for secure installation in systems that support LRDIMM modules

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.
