Samsung M386A8K40BM1-CPB

Overview

The Samsung M386A8K40BM1-CPB is a 64GB DDR4 server memory module designed to deliver large capacity and reliable performance for enterprise-grade servers. Operating at 2133 Mbps with a low 1.2 V voltage, it balances speed and energy efficiency, making it suitable for data centers and high-demand computing environments. Its load-reduced DIMM (LRDIMM) architecture reduces electrical load on the memory controller, ensuring stable operation even when multiple modules are installed across all memory channels.

Key features

• Load-reduced design that buffers data signals to maintain signal integrity and system stability under heavy workloads
• High capacity of 64 GB per module to support memory-intensive applications like virtualization and in-memory databases
• Energy-efficient operation at 1.2 V to help reduce power consumption in large server deployments
• Standard 288-pin DDR4 form factor for easy installation in compatible server motherboards
• 4-rank by 4-bit organization enabling higher memory density without compromising performance

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.
