Description

Overview

The Lenovo 4XG7A63443 is a server processor built around the Intel Xeon Silver 4309Y, designed to handle enterprise workloads that require reliable and efficient processing power. With eight physical cores and sixteen threads, it provides ample capacity for virtualization hosts, database servers, and application clusters. The processor runs at a base clock of 2.8 GHz and can boost up to 3.6 GHz, ensuring responsiveness during peak demand periods.

Supporting up to 6.14 TB of DDR4 memory and featuring a 12 MB L3 cache, this CPU is well suited for memory-intensive tasks such as large virtual machines and in-memory databases. Its 10 nm architecture and 105 W thermal design power strike a balance between performance and energy efficiency, making it a practical choice for Lenovo servers certified for the Xeon Silver 4300 family.

Key features
  • Eight cores and sixteen threads enable efficient multitasking and parallel processing for demanding server applications.
  • Intel Turbo Boost technology increases clock speed up to 3.6 GHz to handle sudden workload spikes smoothly.
  • Support for up to 6.14 TB of DDR4 memory allows for large datasets and virtual environments to operate without bottlenecks.
  • 12 MB L3 cache reduces latency by keeping frequently accessed data close to the processor cores.
  • Energy-efficient 105 W thermal design power helps maintain lower operating costs and thermal output in server racks.
  • Compatibility with Lenovo servers certified for the Xeon Silver 4300 series simplifies upgrades and new deployments.

Product warranty

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.
