INTEL Xeon 6138 2.00GHz CPU
The Intel Xeon Gold 6138 is a 20-core, 40-thread processor from the first-generation Intel Xeon Scalable family (Skylake-SP), built for mainstream two-socket enterprise servers and workstations. It suits virtualization hosts, compute nodes, and storage/controller workloads that benefit from high core counts at a moderate 125 W TDP. Note that it uses the FCLGA3647 socket, so verify motherboard and BIOS compatibility before ordering as a replacement or upgrade.

Good to know
- Requires an LGA3647 platform supporting first-generation Xeon Scalable (Skylake-SP); confirm BIOS/firmware support with your board vendor, as newer 2nd-gen Cascade Lake CPUs are not drop-in on all sockets despite the same socket.
- Within the Xeon Gold range, the 6138 sits in the upper mid-tier: more cores than the 6132/6136 models, a practical balance of core count and 2.00 GHz base frequency for virtualization and dense compute.
- As a discontinued part, stock is typically pulled-tested surplus or refurb units — request batch consistency and test reports (e.g., full-load burn-in results) when ordering in volume for server builds.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
