Samsung M393A1G43DB0-CPB

Overview

The Samsung M393A1G43DB0-CPB is an 8GB DDR4-2133 registered DIMM server memory module designed to provide reliable and stable performance in demanding server environments. It operates at a data rate of 2133 Mbps and uses low 1.2-volt power, balancing energy efficiency with consistent speed. Equipped with error-correcting code (ECC), this module helps maintain data integrity by detecting and correcting errors automatically, which is essential for critical server operations.

Its (512Mx8) x18 component structure and support for up to two ranks per DIMM, combined with an onboard register that buffers clock, command, and control signals, enhance signal quality and stability when multiple modules are installed. The 288-pin layout ensures broad compatibility with server motherboards that require registered ECC memory.

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.
