You can finally use a Ryzen 9 5900X with this ASRock motherboard

AMD Ryzen 5000 desktop processors, which initially didn’t support older X370 motherboards, has finally received its first legacy X370 support from motherboard vendor ASRock.

ASRock announced an official BIOS for its X370 PRO 4 motherboard, which has been listed to support Ryzen 5000 processors. Users who want to make the upgrade to the new chips on their old motherboard can do so by going to the official website, downloading and then flashing a new BIOS built for the newer chips.
