hrm, this complicates things.
Every single Asus board I ever bought had issues, no BS, 'every single one'.
On Asus Australia they have 3 x Asus X570-E, compare all 3 and I don't see one single specification difference.
Look on the ROG site again 3 model Asus X570-E, all the spec exactly the same. What tha...beep??
In recent years an Asus Z87, none of the USB ports would charge an iPhone, even the advertised Super Power Fast charge USB ports.
Went through RMA 3 times with replacement boards, none of them worked, tried beta firmwares, nothing worked, Asus gave up in the end.
Went through exactly the same thing with the Z97, only bothered with 2 RMA.
Had 2 GPU's in each of those boards, they both refused acknowledge the single LCD monitor connected to the GPU in the Slot 1, that centre monitor was ignored. Either the left or the right monitor connected to the second GPU in the last PCIe slot was recognised and always switched between each other, you know the monitor that post and BIOS info was displayed on, always randomly switched, so painful. Asus blamed NVidia, NVidia blamed Asus...Oh my...what.
Have an ASUS Z490 can't even remember now exactly but updated the BIOS to the then current version and some hardware things stopped working, had to revert back to old bios to gain functionality back...wow that company has a very poor record of releasing functional products, sure after a year of BIOS updates they may get it right, but I don't pay to be test mule.
Suppose similar situation with a Gigabyte board back in 2001/2002, the Promise raid controller never worked, corrupted the disks every time, same deal RMA new board, beta BIOS testing...meh, they never got that working either.
