New Agesa ComboAM4v2 126.96.36.199 BIOS updates for motherboards with AM4 socket are causing performance issues according to several users. Biostar, Gigabyte, and MSI, among others, have already made the update available.
Users report, among others via reddit After installing ComboAM4v2 188.8.131.52, I lowered clock speeds up to 150Hz with Ryzen and Athlon CPUs. Also, the overclocking parts of the BIOS menu will not display correctly, and AMD’s Precision Boost Overdrive system features are missing. From Blog post on Deskmodder It shows that overclockers in particular will be affected by inconsistent performance. There are also users who do not experience any issues with the respective AMD Generic Encapsulated Software Architecture version.
It depends on the AM4 motherboard manufacturer, whether Agesa ComboAM4v2 184.108.40.206 is already available, so ComputerBase details† Agesa by AMD is an essential platform that manufacturers use in their resumes. Biostar, Gigabyte and MSI are said to have already included Agesa ComboAM4v2 220.127.116.11 in the new bios update. The last manufacturer has pulled the update now. Asus has also beta testing 18.104.22.168 among users, and after persistent issues, it has moved to the next Agesa ComboAM4v2 22.214.171.124b beta.
For now, according to ComputerBase, it would be wise not to install a new BIOS update based on Agesa ComboAM4v2 126.96.36.199. It is said that 188.8.131.52c is the latest stable version of Agesa. This version will not cause any performance issues and offer the usual options for overclocking.
