I think you're completely wrong, be careful with that.
Speed (frequency) alone doesn't break anything; the real danger is extreme heat and high voltages.
Of course, provided you do not exceed these frequencies::

As I understand it, overclocking isn't bad as long as we maintain good temperatures. It is high temperatures—not high frequencies—that cause damage. And how do you keep temperatures low? By adjusting the voltages. Please correct me if I'm wrong.

I'm not referring to the frequencies, but rather the voltages. If you didn't modify the voltages, it's very likely not the same error.
