https://wccftech.com/asus-not-supporting-amd-ryzen-5000-cpus-on-x470-motherboards-suggests-x570-b550-upgrade/ > A few months back, AMD released a statement saying that they will support their Ryzen 5000 CPUs on older 400-series motherboards (X470 & B450). While X570 is getting the first round of support, it seems like some board partners would still be focusing more towards their 500-series lineup than 400-series as hinted by ASUS. > The story comes from AMD's subreddit where a user contacted ASUS to ask for the support of AMD Ryzen 5000 CPUs on his motherboard. The motherboard in question is the ASUS ROG Crosshair VII HERO which is based on the X470 chipset. In their reply, ASUS says that according to its engineers, they have no plans for the Crosshair VII HERO to support the Ryzen 9 5900X CPU. The company rep even goes off to advise the user to purchase an X570 or B550 chipset-based motherboard that will support the Ryzen 5000 series CPUs.
