So I just purchased an AsRock B450M Pro4 motherboard with a Ryzen 2600x. I went to Asrock's website to see if I need a bios update and now I'm totally confused whether I should get the latest or possibly downgrade to an earlier bios. The bios that shipped with the motherboard was v3.80 AGESA Combo AM4 184.108.40.206. This bios isn't available for download from the AsRock website. There is a lower version 3.60 AGESA Combo AM4 220.127.116.11 ABB, and there is a newer 3.90 AGESA Combo AM4 18.104.22.168 Patch B. BUT, both 3.60 and 3.90 have a notation on the website: "*ASRock do NOT recommend updating this BIOS if Pinnacle, Raven, Summit or Bristol Ridge CPU is being used on your system" I'm guessing the 3.80 bios was buggy enough that it's not even posted on their website and I should ditch it. There is also a v3.50 bios available for download which was the last bios before the notations that the new bioses aren't recommended with my 2600x.
