If you're able to unlock the bios, then you also need to disable those features that I said to disable.
Basically, disable everything in that center pic except for Execute Disable Bit.
After that, there may be a keyboard thing you can do in order to unlock the BIOS. It might be something like F1, or Ctrl+F1, or something. If not, then there's nothing you can do outside of using software to overclock your system. But, that wouldn't be worth it because you probably wouldn't get a big enough overclock to make any difference anyway. All that would happen is it would create more heat and possibly make benchmark numbers higher. But as for real-world performance, you wouldn't feel it very much if you used software to overclock instead of the BIOS.
So, if you find out that it's definitely not able to be unlocked (you could call the manufacturer), then I say that it's best to just give up and re-enable those features in the bios and just leave it. After all, pre-built systems are not designed to be overclocked. They're designed to be purchased, and then left as they are.
