Found his thread and checked ASUS website, it was indeed BIOS. I'm so used to these download pages be dead for years, that I didn't expect to find SEVERAL new bios version already since the last week I built a PC, the team must be on fire with this new board. The stupid Armoury Crate still offers an older BIOS for download, I trusted it in the first place, isn't its only job is to monitor things like that like a hawk.
