It's the correct socket, but when selecting the CPU with the motherboard in PCPartPicker it indicates a BIOS update is needed. There’s no online info about this requirement. I’m just confirming compatibility between the CPU and motherboard. If unsure, get a recommendation from someone experienced.
They work well together, though the X570 models were released with 3000 CPUs. The 5000 series wasn’t available then, so updating to newer CPUs required a BIOS update. Since the 5000 lineup was already established, most current X570 boards should include a compatible BIOS by default. However, there’s no assurance that any board—whether new or old—hasn’t been sitting unused for years.
I recommend a brief review of the board naming. The X570 models had an updated revision where an 'S' was included. For instance, I own the Aourus Master X570, but the most recent version listed is Aorus Master X570s. The S-series boards no longer needed the fan to cool the chipset, making them quieter. Other updates included adding an extra M.2 slot on certain models. If your board has been sitting on the shelf for a while, you might be getting an older version without the latest enhancements before AMD's AM5 transition. However, I do possess the mid-range model—its second revision has four M.2 slots and the S variant has four as well. Always check the manufacturer’s site and consider using comparison tools if available. I hope this doesn’t cause confusion, but unless a board is discounted and fits your budget, prioritize having the newest revision for general improvements.
