Its all simple math.
CPU multiplier by the Front Side Bus speed :P = CPU speed.
(CPU Mulit)X(FSB)=(CPU Speed)
9 X 300 = 2700 = 2.7GHz
this is just a rough example.
There are many variables that come into play, but that is what it comes down to.

Phelan's got it exactly correct.
Of course a big part of it is the make of your processor. Intel and AMD differ greatly. And you will need a decently powerful PSU, depending on your setup I would reccomend a 750Watt PSU or over.
AMD Tend to have their CPU Multiplier unlocked, what this means is you dont have to adjust the FSB AT ALL.
For example:
Lets say I want to get my 2.6 Ghz AMD processor to 3.2 Ghz. The processor has a multiplier of 8. So this means:
2.6/8 = 0.325
FSB=325 because 325 x 8= 2.6(GHz)
So with an AMD processor, I could take that multiplier and up it as many times as I want. So:
325 x 9 = 2.92 GHz
324 x 10 = 3.24 GHZ - Our goal.
For intel processors its much more difficult because all of their current processors, (Excluding the Xtreme Editions), have locked multipliers. Which means you cannot change it.
So lets say I wanted to overclock an Intel processor from 2.6 to 3.2, since we don't have a changable multiplier, we need to raise the FSB Speed in order to achieve our goal.
If the multiplier is 8:
2.6/8 = .325 = 325 Mhz
FSB=325 because 325 x 8= 2.6(GHz)
Since this is a processor with an unchangable multiplier, we need to change the front side bus to increase the GHz.
400 x 8 = 3200
Speed = 3.2GHz
Then you must take into consideration your ram speed because unless you have an expensive, well made motherboard, your ram speed scales with your FSB.
There are alot of guides out there, im sure you can find one for your specific setup.
By the way, this is all done via the Bios, never use In-OS overclocking software, it screws stuff up in the end.
