A while ago I bought a 2600X processor at a blowout price. I had planned to use it in my ROG B350F MB . I plopped it in and it didn't work. Seems I would need a BIOS upgrade. Things came up and I shelved the project. Now months later I finally have the time and instead of flashing the BIOS on my old MB I got a deal on a new B550 TUF Gaming MB. I just got home to find that my 2600X won't work. Is that true ??
Hello!
Looks like that is indeed the case. The motherboard in question only lists Zen2 and Zen3 CPUs (Ryzen 3000 & 5000 series) in it's supported CPU list.
You can still flash the ROG B350F to support your CPU, but you will likely need a Ryzen 1000 series CPU just to do the flashing.
