About This Product
Overview
The Intel Xeon Gold 6138 is a server processor built for compatible LGA3647 platforms and designed to handle workloads that benefit from high core and thread counts. With 20 cores and 40 threads, it is well suited to environments where parallel processing matters, including virtualization, database tasks, analytics, and general enterprise server use. Its 2.00GHz base clock and 3.70GHz turbo clock provide a balanced mix of steady operating frequency and responsive performance when workloads increase. The 27.5MB Smart Cache helps support efficient data access, while DDR4-2666 memory support and PCIe 3.0 compatibility make it a practical fit for systems that need dependable platform support. For IT teams, resellers, and system builders working with supported hardware, this CPU offers a strong option for upgrading or maintaining a server configuration with proven Intel Xeon architecture.
Performance & Scalability
With 40 threads available, the Xeon Gold 6138 is designed to support workloads that can take advantage of multiple simultaneous processes. This makes it a useful choice for server environments where efficiency and responsiveness are important, especially when several users, services, or virtual machines are running at the same time. The 125W TDP reflects a processor intended for serious compute use, and the turbo frequency helps the CPU adapt to higher-demand tasks when additional performance is needed. In compatible systems, DDR4-2666 memory support can help maintain a stable data path between the processor and memory subsystem, while PCIe 3.0 support allows integration with a range of expansion devices and storage controllers. For organizations looking to scale a server platform within the limits of supported hardware, this processor provides a capable foundation for multi-threaded workloads without unnecessary complexity.
Storage Flexibility
Although this is a CPU rather than a storage device, its platform support plays an important role in how a server handles storage-related tasks. PCIe 3.0 support can be valuable in systems that use add-in storage controllers, RAID cards, or high-performance expansion devices, helping the platform work smoothly with a variety of storage configurations. In addition, the processor’s multi-core design can assist with storage-heavy workloads such as file services, virtualization hosts, and applications that rely on frequent data movement. When paired with compatible memory and motherboard infrastructure, the Xeon Gold 6138 can support a balanced server build that is ready for both compute and storage demands. This makes it a practical component for environments where storage performance depends on the overall strength of the server platform.

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.
