Socket sTR5 is aland grid array (LGA)CPU socket designed byAMD.[1] It supports theZen 4-basedRyzen Threadripper 7000 series, which launched in November 2023.[2] It is also used for theZen 5 Ryzen Threadripper 9000 series.
sTR5 is a socket for bothRyzen Threadripper HEDT andRyzen 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, andWRX90 for professional workstation systems. TRX50 supports both Threadripper and Threadripper PRO CPU models, while WRX90 supports only Threadripper Pro models.[1]
Socket sTR5 supportsDDR5 memory of theRDIMM type withECC, as well asPCIe 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]
