Socket TR4 (sTR4) also Socket SP3r2 is land grid array microprocessor socket designed by AMD for their Threadripper family supported by the Zen and Zen+ microarchitectures. This socket is designed for ICs with a 4094-contact FCLGA packages.

Overview

sTR4 is a socket specifically designed by AMD for their Threadripper family of HEDT processors and is supported by processors based on the Zen and Zen+ microarchitectures. Physically, the package is identical to the one used for Socket SP3 for their EPYC processors, however the features are much reduced.
