Samsung M393A8G40AB2-CVF

Overview

The Samsung M393A8G40AB2-CVF is a 64 GB DDR4 registered DIMM designed specifically for servers that require large memory capacity and reliable, continuous operation. Operating at 2933 MT/s with a low voltage of 1.2 V, it provides fast data transfer speeds while minimizing power consumption, making it well suited for dense server environments and energy-efficient data centers. Its built-in error correcting code (ECC) ensures data integrity by detecting and correcting single-bit errors, which is critical for workloads like virtualization and transactional databases.

Key features

• Registered DIMM architecture buffers clock, command, and control signals to reduce electrical load on the memory controller, enhancing stability in multi-module setups
• ECC with 8-bit parity enables real-time error detection and correction, protecting sensitive data and maintaining system reliability
• Low operating voltage of 1.2 V helps reduce overall power consumption in server racks
• Supports single- or dual-DIMM per channel configurations for flexible memory expansion
• 288-pin form factor with 2R x 4 organization ensures compatibility with a wide range of DDR4 2933 RDIMM server motherboards
• Simple installation process allows immediate use of additional memory capacity following server population guidelines

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.
