Socket sTR5 is a land grid array (LGA) CPU socket designed by AMD.^[1] It supports the Zen 4-based Ryzen Threadripper 7000 series, which launched in November 2023.^[2] It is also used for the Zen 5 Ryzen Threadripper 9000 series.

sTR5 is a socket for both Ryzen Threadripper HEDT and Ryzen Threadripper Pro workstation processor lineups. This is unlike the preceding (3000 and 5000 series) generations of Ryzen Threadripper / Threadripper Pro processors, which were on separate sockets, sTRX4 and sWRX8 respectively.

The sTR5 socket has two chipsets available: TRX50 for HEDT consumer systems, and WRX90 for professional workstation systems. TRX50 supports both Threadripper and Threadripper PRO CPU models, while WRX90 supports only Threadripper Pro models.^[1]

Socket sTR5 supports DDR5 memory of the RDIMM type with ECC, as well as PCIe 5.0. It does not support non-registered DIMMs, non-ECC RAM, or DDR4.^[3] The maximum number of memory channels is 8 and the maximum number of PCIe 5.0 lanes is 128 with a Threadripper PRO CPU and a WRX90 motherboard.^[4]
