Samsung M393A2G40EB1-CPB

Overview

The Samsung M393A2G40EB1-CPB is a 16GB DDR4 registered DIMM designed specifically for server environments that demand reliable memory capacity and steady performance. Operating at 2133 Mbps with a 288-pin interface, it supports data-intensive tasks such as virtualization, database management, and high-traffic web services. Its built-in register stabilizes signals between the memory controller and DRAM chips, ensuring consistent operation even when multiple DIMMs are installed per channel.

Key features

• Registered DIMM architecture that smooths clock, command, and control signals for stable memory bus operation
• Error-correcting code (ECC) with 8-bit parity that detects and repairs single-bit errors to protect critical data
• 2R x 4 rank organization optimized for two-DIMMs-per-channel server motherboards
• Low voltage operation at 1.2 volts to reduce power consumption in always-on server racks
• Easy installation into compatible DDR4 slots without requiring special tools or complex setup

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.
