Samsung M393B5270DH0-CK0

Overview

The Samsung M393B5270DH0-CK0 is a 4GB registered DDR3 memory module designed for server environments where stability and data integrity are essential. Operating at 1600MHz, it delivers consistent performance while incorporating error-correcting code (ECC) with an 8-bit parity signal to automatically detect and correct memory errors. This module is built to support demanding workloads and maintain uptime in critical systems.

With a 240-pin layout and support for both 1.5V and 1.35V operation, it offers flexibility for various server configurations. Its registered design improves signal integrity by managing clock, command, and control signals, making it ideal for systems running multiple memory modules simultaneously.

Key features

• Registered DDR3 DIMM that enhances system stability by buffering control signals
• Error-correcting code (ECC) with 8-bit parity to maintain data accuracy and reduce system crashes
• Dual voltage support (1.5V and 1.35V) for compatibility with different server power requirements
• Supports x4 and x8 memory organizations and up to two ranks per DIMM for efficient memory expansion
• 240-pin form factor compatible with standard server motherboards

These features ensure reliable operation in server and workstation environments where memory errors can cause costly downtime or data loss.

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.
