Question about ASUS ROG Strix X570-I Gaming

That is a pity. Now how do I know if this MB is directly compatible with ZEN3 or if I need a ZEN2 so that I can update the BIOS since the ZEN3 is not even running yet?

I know, it's too old a version. I contacted Asus support, they said you should contact the dealer (digitec), who will then send you an old CPU with which you can do the update. I am now in contact with digitec. The board does not have BIOS Flashback.

...I'm sure no one here knows, because it varies from mainboard to mainboard!
