Good morning everyone. I currently use a fx-8320 and a ga990xa-ud3 motherboard It is updated to the latest version of bios to avoid the famous bug of the gigabyte boards when doing overclock The problem is the following: I have placed at the time a rx 460 and then a rx 550. None works correctly. The first gave problems when installing the drivers and the second directly does not give video. I know the problem is with the motherboard, because the store found that the rx 460 worked However, nvidia pascal works without problem. How can i fix this?. I'm surprised that a not so old socket is giving compatibility problems. Without being able to use any modern radeon I have limited to choose graphics card.
