Hello! Interesting idea, generating an n Hz signal from n one Hertz signals. There are ways to generate higher frequency signals from lower ones, but I'm afraid that's not one of them!

But perhaps you're actually trying to increase clock speed to speed up your computer. On some machines it may be possible to increase the clock speed by 5% or 10%, but it's really not worth the bother -- much better just to buy a new motherboard -- they're pretty inexpensive these days.

The problem with increasing clock speed is that it's already pretty close to maximum for the given CPU chip. What really governs the maximum speed your computer runs is the CPU's physical properties. Primarily, it's how small and closely-packed the transistors on the chip can be manufactured. The smaller and closer they are, the less time it takes for the signals to travel. As chip layout continues to shrink, we get faster and faster computers.
