Intel Xeon SR3B2 12-core processor

The Intel Xeon SR3B2 is a 12-core server processor with a base frequency of 3.00 GHz and 24 threads. It uses the FCLGA3647 socket and supports up to 768 GB of memory. The unit is sold as a clean pull with minor cosmetic signs of prior use and contains the CPU only.

Suited for multi-threaded server workloads

This processor suits administrators upgrading or repairing compatible dual-socket platforms that require 12 cores and the FCLGA3647 interface. It is not for laptop repairs, desktop consumer boards, or systems needing integrated graphics. Buyers who need a manufacturer warranty or retail packaging should look elsewhere.

Straightforward socket installation

Installation follows standard FCLGA3647 procedures: align the processor, lower the load plate, and secure the lever. The clean-pull condition means the gold contacts are intact and no caps are missing, so seating issues are rare. The main risk is applying uneven pressure or using a cooler that does not match the socket mounting pattern.

Questions about this item

What motherboard socket is required for this FCLGA3647 processor?

The processor uses an FCLGA3647 socket, so the motherboard must provide that exact socket to install the 12-core CPU.

Will this 12-core, 3.00 GHz CPU fit in the same FCLGA3647 socket as my current Xeon processor?

Yes, any processor designed for the FCLGA3647 socket shares the same physical interface, allowing a direct swap provided the platform firmware supports the Gold 6136 model.

How can I verify the processor is running at its 3.00 GHz base frequency after installation?

Check the reported base clock in the system BIOS or an operating-system utility such as CPU-Z; it should show 3.00 GHz for all 12 cores under load.
