Hi,

I'm using the 10G Lan variant of this board with a 3700x and haven't had any issues.

There is a "beta" bios version available from ASRock which updates the AGESA version to 1.0.0.6 (https://download.asrock.com/BIOS/Server/X470D4U(L3.37)ROM.zip) which might be worth trying? I'm using the equivalent version on my board.

Kind Regards
