About This Product
Overview
The Intel Xeon Gold 6138 is a server-class processor built for systems that need dependable multi-core processing and broad platform compatibility. With 20 cores and 40 threads, it is well suited to workloads that benefit from parallel execution, including virtualization, database tasks, application hosting, and other compute-intensive environments. Its 2.0GHz base clock and 3.7GHz turbo clock provide a balanced mix of steady operating frequency and responsive burst performance, while the 27.5MB Smart Cache helps support efficient data access during active workloads. Designed for the LGA3647 socket, this CPU fits into compatible server and workstation platforms that use Intel Xeon Scalable architecture.
Performance & Scalability
With a 125W TDP and support for DDR4-2666 memory, the Xeon Gold 6138 is intended for systems that need strong processing capability alongside modern memory bandwidth. The 40-thread design helps improve throughput in multi-user and multi-tasking scenarios, making it a practical choice for environments where several services or virtual machines may run at the same time. PCIe 3.0 support also allows the processor to work with compatible expansion hardware in server builds that rely on add-in cards, storage controllers, or network adapters. For organizations or builders looking to scale performance within an LGA3647 platform, this processor offers a solid foundation for balanced compute workloads.
Storage Flexibility
While this processor does not include storage itself, it supports the platform capabilities needed in modern server and workstation systems. PCIe 3.0 connectivity can be used with compatible storage expansion solutions, helping build systems around fast local storage or controller-based configurations. Combined with DDR4-2666 memory support, the Xeon Gold 6138 can contribute to a responsive system architecture that works well in data-driven environments where storage access, memory throughput, and CPU performance all matter. It is a strong fit for builds that pair processing power with flexible storage design.
Why Choose This Product?
The Intel Xeon Gold 6138 is a practical option for buyers seeking a proven server CPU with a high core count, solid cache capacity, and support for established enterprise platform features. Its specifications make it a good match for virtualization hosts, business servers, and workstation systems that need consistent multi-threaded performance. Because it uses the LGA3647 socket and supports DDR4-2666 memory, it integrates into compatible systems designed around Intel Xeon Scalable processors. For IT hardware resellers and system builders, it is a versatile component for upgrading or maintaining supported server platforms.
About this processor
Intel Xeon Gold 6138, a 20 core, 40 thread LGA3647 processor at 2.0GHz with 3.7GHz turbo, 27.5MB cache and DDR4-2666 support, refurbished. Tested and stocked in Doha, delivered across Qatar within a day.
The Xeon Gold 6138 is the twenty core mainstay of Intel's first generation Xeon Scalable family for the LGA3647 socket. A 2.00GHz base and 3.70GHz turbo across 20 cores and 40 threads, 27.5MB of cache, six channels of DDR4-2666 memory and 48 PCIe 3.0 lanes at a 125W rating make it the processor most 14th generation Dell and Gen10 HPE servers were built around. Two of them give a server 40 cores and 80 threads.
It is the most common processor in ServerDove's Doha stock for a reason: buyers in Qatar fit refurbished Gold 6138 pairs to 14th generation Dell and Gen10 HPE rack servers for virtualisation, where thread count per socket at a moderate wattage is exactly what a hypervisor wants.

Part numbers and identification
Buyers search for "Xeon Gold 6138", "6138 CPU", "Gold 6138 20 core" and "6138 LGA3647".

| Family | Xeon Scalable, first generation, Gold 6100 series |
Specification
At 125W the 6138 is comfortably within the cooling envelope of every 1U and 2U server of its generation with the standard heatsink, which is one reason it is so widely fitted.
| Cores | 20 |
| Threads | 40 |
| Base clock | 2.00GHz |
| Turbo clock | 3.70GHz |
| Smart Cache | 27.5MB |
| Socket | LGA3647 |
| TDP | 125W |
| Memory support | DDR4-2666, six channels |
| PCIe | PCIe 3.0, 48 lanes |
The Gold 6138 also appears in ServerDove's assembled servers and workstations, so a buyer who already runs one can add a second identical processor from the same stock, which keeps the pair matched. Two processors of the same model, stepping and microcode are what the server firmware expects, and a mismatch produces warnings at boot.
Twenty cores at 2.00GHz favours parallel work over single threaded speed. Hypervisors, container platforms, web farms and batch processing all scale across the threads; a database licensed per core or a single threaded application would prefer a faster twelve core part. Memory bandwidth from six channels per socket is generous, and the processor drives 2666 MT/s DIMMs at full speed.
Installation
Any first generation Xeon Scalable server accepts the 6138 without a firmware update. The processor clips into its carrier, the carrier attaches to the heatsink, and the assembly is lowered onto the LGA3647 socket and fastened in the numbered screw order printed on the heatsink. Use the carrier that matches the processor type and fit both processors of a pair with identical part numbers. Populate memory six DIMMs per socket for full bandwidth.
