I know what it mean. It's just definitely, very, VERY bad idea. As You can see, You don't gain any benefits form such insanely unwise settings (more likely, regressions due to instability), and You're on perfect way of frying Your device, if - accidentally - any process locks Your CPU at max usage, for prolonged period of time.

Of course, You're free to do whatever You want with Your device, but if want to remain in "sane side of the Force", don't overclock to more than 900 mhz.
