So my friend is trying to update his motherboards bios since we believe that could be a cause to some of his pc problems. When looking for this specific motherboard we only find the Z390 GAMING X (rev. 1.0) or Z390 GAMING X (rev. 1.1). We cant find the x-cf version of the motherboard and are wondering which one should we get the bios update from. If anyone has a direct link to this specific motherboard website for the bios or a suggestion on which bios rev we should choose, we would be grateful for the help.
