Here's the obligatory disclaimer about breaking past manufacturer specifications: overclock at your own risk. Most hardware manufacturers, including AMD, do not warranty damage done by overclocking, even when using utilities they provide. Tom’s Hardware or this author cannot be held responsible for any damages that may occur while you overclock.
