Default Overclocking question.

Got a basic understanding of the how. But i've often wondered the what. In particular, the multiplier. When changing the multiplier what exactly am i changing in the operation of the CPU to change the operating frequency?

Default Re: Overclocking question.

The CPU's speed can be determined by its multiplier multiplied (duh) by the FSB e.g. in my CPU it is a 17x multiplier times by 200FSB to give me 3.4Ghz. By increasing the multiplier, u are simply multiplying 200 by one more, so if i increased mine to 18x (for argument's sake...) then i would have a clock speed of 3.6Ghz and so forth...but this will NOT affect my quadpumped FSB, so i would still have a FSB of 800Mhz, even though my core clock is higher.

CPU: Intel Core 2 Quad Q9450 @ 3.4GHz
Motherboard: Foxconn Blackops X48
Memory: 8GB DDR3 (1361MHz)
Graphics: ATI 5850 1GB GDDR5
Hard Drives: 1 x 500GB, 1 x 1TB
Case: Antec 900
OS: Server 2008 R2 64bit

yea, but what is the multiplier changing? the number of threads executed? is it just another descriptor given to how the speed is calculated? or what?
