About This Product
Overview
The Intel Xeon E5-2643 v3 is a server-class CPU designed for systems that use the LGA2011-3 socket. With 6 cores and 12 threads, it is well suited to workloads that benefit from strong multi-threaded processing while still maintaining responsive single-thread performance. Its 3.40GHz base clock and 3.70GHz turbo clock make it a practical choice for environments where consistent compute capability matters, and the 20MB Smart Cache helps support efficient data access during demanding tasks. As part of the Xeon family, this processor is intended for professional platforms that require dependable operation and compatibility with server and workstation hardware built around DDR4 memory and PCIe 3.0 expansion.
Performance & Scalability
With 6 cores and 12 threads, the Xeon E5-2643 v3 provides a balanced mix of parallel processing and clock speed, making it suitable for a range of business and technical workloads. The higher base frequency can be beneficial in applications that rely on strong per-core performance, while Hyper-Threading support helps improve efficiency in multi-tasked environments. PCIe 3.0 support allows the processor to work with compatible expansion devices, and DDR4-1866 memory support helps align the CPU with modern platform requirements. For organizations maintaining or upgrading an existing LGA2011-3 system, this processor can be a straightforward option for restoring or extending platform capability without changing the underlying motherboard architecture.
Storage Flexibility
Although the processor itself does not include storage, its PCIe 3.0 support and platform compatibility can help support systems that use a variety of storage configurations through the motherboard and attached controllers. In server and workstation builds, the CPU plays an important role in handling data movement between memory, storage interfaces, and expansion cards. When paired with compatible hardware, the Xeon E5-2643 v3 can fit into systems that use SSDs, RAID controllers, or other storage-related add-in cards, making it useful in environments where storage performance and expandability are important considerations.
Why Choose This Product?
This processor is a strong fit for buyers looking for a genuine Intel Xeon CPU for an LGA2011-3 platform. It offers a clear specification set that is easy to match against existing hardware requirements, including 6 cores, 12 threads, DDR4-1866 memory support, and a 135W TDP. For IT teams, resellers, and system builders working with compatible servers or workstations, it provides a practical replacement or upgrade path within an established platform. The combination of Xeon reliability, solid clock speeds, and broad platform support makes it a useful component for maintaining professional systems with known compatibility needs.

Why Buy a Refurbished Products?
Refurbished enterprise servers offer enterprise-grade performance at a fraction of the new price.
Up to 70% Cost Savings
Refurbished R650xs units deliver identical hardware capability to new, at significantly lower upfront cost — freeing budget for CPUs, RAM, and storage.
Fully Tested & Verified
Every unit undergoes comprehensive hardware diagnostics before dispatch. POST tests, burn-in, memory checks, and power supply verification are standard.
Immediate Availability
Unlike new enterprise servers with lead times of weeks or months, refurbished stock is ready to ship within 24 hours of ordering.
Same Performance
The hardware inside the R650xs performs identically whether purchased new or refurbished. The 3rd Gen Xeon platform, PCIe Gen4, and iDRAC9 are unchanged.
