I have a MSI b350 tomahawk with a Ryzen 3 1200. I want to upgrade the cpu to Ryzen 7 3700x. I understand that I need to update my BIOS for my new cpu, but have no idea which BIOS update to choose. I've tried doing my own research, but I can't find the correct information, since this is all new to me. Can anyone please help me with finding the right BIOS update?
