Hi Catch,
Firstly the mobo has to be capable of having the FSB alterred within the BIOS.
Secondly, if that can be done there must be 'dividers' allowed too. THese are used to ensure the PCI and AGP busses run at the correct speeds of 33Hz and 66Hz respectively.
Now memory is another thing to consider, the RAM must be capable of running at higher speeds too. The speed RAM runs at is dependent upon FSB speed and will usually be set within the BIOS
Right, that is one bit out of the way. Now the tricky bit.
To be able to just change the FSB, you must first consider how the CPU runs at the speed it does. This is achieved by a multiplier within the CPU and is factory locked (ie it can't be changed >
) if this were unlocked you would be free to experiment
(that's what I need to do when I overclock the CPU 8)) The CPU speed is governed by the FSB speed multiplied by the multiplier. eg a FSB of 133 and multiplier of 10x gives a CPU speed of 1.33GHz A locked 10x CPU would not be capable of making the jump from 100Hz to 133Hz ie 1GHz to 1.3GHz
However, by increasing the FSB by a little at a time, ie 101Hz, 102Hz etc, you are overclocking the CPU (and all the other PC components) Eventually, those components will become unstable and cause crashes. There are other things that get tweaked along the way like CPU core voltage etc.
I do not recommend messing with these unless you know what you are doing, have adequate CPU cooling and realise that you invalidate warranties, and can destroy your CPU.
Here endeth your first lesson in overclocking
