q- code 53 means there is an incompatibility or problem with the RAM you selected.
if it boots and works fine with BIOS#2 you should have an option when you go into that bios to flash BIOS#1 then don't you ?
No that option doesnt exist in asus pricey boards bios

BIOS flashback only works for me with the USB sticks formatted in FAT16, and FAT16 (aka FAT) requires a 4GB or smaller stick. It has never worked for me with a NTFS or FAT32 USB stick, although I have tried numerous times with my Rampage VI Apex and the Maximus X Hero.
