Hi, I should receive my 5900x on january 19th. I have an asrock b550 pg velocita and it doesn't have a bios flashback and I don't have an older CPU(3000 and older). I need to update my motherboard. I heard that I can email amd and they might loan me an APU to update my board. I did some research and it says it's only for b450/x470. Can I still get one for a b550 motherboard? Thank you in advance for you answers.
