Connectivity and compatibility

This memory module fits into standard 288-pin DDR4 RDIMM slots found in a wide range of server motherboards. Its registered design ensures compatibility with platforms that require buffered memory to maintain signal quality and system stability. The support for two DIMMs per channel and multiple ranks per DIMM allows system administrators to optimize memory configurations for virtualization, database management, and high-performance computing tasks.

Performance and reliability

With integrated parity and an on-board register that manages clock and control signals, this module reduces the risk of single-bit errors that can lead to system failures. Its 2933 Mbps speed supports fast data access and transfer, which is essential for maintaining smooth operation in demanding server workloads. The low operating voltage helps reduce power consumption, contributing to more efficient data center operations.

Ideal uses and environments

This Samsung memory module is well suited to enterprise environments where uptime and data integrity are critical. It works effectively in virtualization hosts, database servers, and high-performance computing nodes that require stable and scalable memory solutions. Its error correction capabilities and robust design make it a strong choice for IT professionals managing mission-critical infrastructure.

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.
