Previously, AMD released the AGESA 220.127.116.11 microcode for the AM5 platform, but some players found that after updating the firmware, the Ryzen 5 7600X processor experienced serious performance degradation. Affected mainly are Ryzen 5 7600X processors with dual CCD chips, AMD seems to disable Core0, and in some cases, the system outright didn’t post because the firmware tried to boot off a single CCD.
AMD quickly discovered this problem, and partners quickly deleted the problematic firmware on the X670/B650 series motherboard support page. According to TomsHardware, AMD has distributed a new version of AGESA 18.104.22.168 to partners. Although the version number has not changed, the system management unit (SMU) has been updated from SMU 84.79.204 to SMU 84.79.210 to solve this problem.
Some motherboard manufacturers have begun to provide new BIOS for their X670/B650 series motherboards, but because it is still in the testing stage, there are still certain risks for players to upgrade now. The importance of the AGESA 22.214.171.124 microcode is that it supports AMD’s recently released new processors, including the 65W Ryzen 9 7900, Ryzen 7 7700, and Ryzen 5 7600, as well as the Ryzen 9 7950X3D, Ryzen 9 7900X3D, and Ryzen 7 7800X3D that will be available next month. The 65W model is already on sale, while the Ryzen 7000X3D series could arrive on February 14th.
