Intel Xeon W-2125 4.00 GHz SR3LM

This Intel Xeon W-2125 processor operates at a 4.00 GHz base frequency with four cores and eight threads. It uses the FCLGA2066 socket and supports up to 512 GB of memory. The unit is a clean pull with minor cosmetic signs of prior use but tests to OEM specifications.

Installation notes and common issues

The package contains the CPU only, so you must supply your own cooler and thermal paste. Handle the processor by the edges to avoid bending the delicate socket contacts. Verify the motherboard BIOS supports this specific model before fitting it, as an unsupported revision will prevent the system from posting.

Compatibility checks before ordering

Confirm your motherboard uses the FCLGA2066 socket and lists the W-2125 in its supported CPU table. Check that your power delivery and cooling solution can handle the thermal output of a four-core Xeon. Ensure the system memory you plan to use falls within the 512 GB maximum supported capacity.
