Asus Maximus XI APEX, Flashed 1901 REbar bios. Make sure you have backedup your bios settings on usb as you will have toi clear the Cmos in order for it to boot post flash. otherwise worked honestly speed is very minimum gain 2% for me in warzone.
Well that is some very sad news. Well I would seriously doubt if they don't update Z370 they will update Z390 either. Complete BS on Asus part not to update these board they are 100 dreds of thousands of these board still in use today.
