Desktop workstation CPU with 14 cores and 28 threads

The Intel Core i9-9940X SREZ5 delivers 14 cores and 28 threads at a 3.30 GHz base frequency and 4.40 GHz max turbo. It fits the FCLGA2066 socket and supports up to 128 GB of memory. The package contains the processor only.

Suits multi-threaded workloads like rendering

This processor targets users who need high core counts for parallel tasks such as video encoding, 3D rendering or scientific computing. Builders who require integrated graphics or a different socket should look elsewhere. The unit is a clean pull with minor cosmetic signs of prior use.

FCLGA2066 socket compatibility is the deciding

The CPU installs only in motherboards with an FCLGA2066 socket. Verify that your board supports this socket before purchase. No other specification overrides this physical requirement.

Questions about this item

What socket does the Intel Core i9-9940X SREZ5 use, and what does that mean for motherboard compatibility?

It uses the FCLGA2066 socket, so it only fits motherboards built for that socket.

What physical space and mounting does the FCLGA2066 package need?

The CPU measures 0.250 by 0.250 by 0.250 and weighs 0.5000; it mounts in a standard LGA2066 socket with the usual retention bracket.

How is the processor installed, and what step do people often miss?

Align the notches, lower the chip gently, close the load plate, and lock the lever — the step many skip is removing the plastic socket cover before seating the CPU.
