Yes, this Cpu is multiplier unlocked, which means it is relatively uncomplicated to overclock. Should be no problem on a b450 mobo, but depends on the model. Most are definitely capable of overclocking this CPU. How far you can overclock it depends on your cooler. With the stock cooler that comes with it, it ran easily with 4.2 GHz / 1.25V all core overclock. With my Dark Rock 3, I can overclock it to 4.5 GHz. Unfortunately, the silicon lottery always plays a role here: if you're lucky, you'll get more, if you're unlucky, you'll get less.
