Samsung M391B5673FH0-CH9

Overview

The Samsung M391B5673FH0-CH9 is a 2GB DDR3 ECC memory module designed to enhance the stability and performance of desktop workstations and entry-level servers. Operating at 1333 MHz with a CAS latency of 9, it provides reliable memory throughput for everyday computing, light virtualization, and file-serving tasks. Its error-correcting code (ECC) capability helps maintain data integrity by automatically detecting and correcting memory errors, making it a solid choice for systems where reliability is critical.

Key features

• Error-correcting code technology that improves system stability by preventing data corruption.
• Operates at 1333 MHz to deliver consistent performance for typical office and server workloads.
• Standard 240-pin unbuffered DIMM form factor ensures compatibility with most DDR3 motherboards.
• Low 1.5-volt power consumption helps reduce overall system energy use without sacrificing speed.
• CAS latency of 9 balances responsiveness and efficiency for smooth multitasking.
• RoHS compliant and halogen-free design supports environmentally responsible hardware practices.

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.
