most likely you couldn't. Not with that BIOS. Not all of them allow you too. If you bought it all put together like at a store then they usually don't let you. And if you do, even if you don't kill the thing, you still just voided the warranty and you cant send it back. I think if you could do it in a BIOS like yours you would have sound it. I really think that you can not do it with your BIOS. I couldn't with my old computer, and i used CPUCool. Its free if you like having to do it every start up, buy it and you wont have to, but I only did it when i needed to. But yeah, don't do what you did again. Mistakes are for learning from. Seriously, don't take another chance like that, not until you know what your doing. That's what this place is for; help. We all make mistake, but we come here to figure out how to do it before hand, and to get advice. My only suggestion is use CPUCool. Software is often the safest and best way to do overclocking.
