Can someone explain multiplier to me

I know this may have already been posted but I have a xp 2200+ and I have OCed it to 1.97 by just stepping up the FSB but can someone explain how adjusting the vcor and multiplier how it can help. PLease include on how I can calculate how it will help or increase my speeds. My Bios allows me to set both the vcore and multiplier but I dont know how to adjusts these.

here is a link that shows all the bios screens

The multiplier is just that. It multiplies the FSB. So 13 mulitplier and 100fsb = 1300. 13.5x133= roughly 1800 ( what your cpu's stock speed is). Changing the multiplier is handy, as you raise it because the board cant handle a higher fsb, or lower it to get a higher fsb at the same clock speed. Changing the Vcore adds more power to the cpu so it can run stable at the higher speeds.

fsb x multiplier = CPU speed. ie: 10 x 155fsb = 1550mhz.

only put vcore as high as you need it to be to run the system stably. Don't put it higher than 1.95 volts (risky) unless you have super good cooling or else you will burn that puppy up.

more vcore = higher temperatures, more stability.

higher fsb = much better performance, better memory performance (but make it too fast and you will need to loosen your memory timings).

higher overall CPU speed = better performance

to change these setting hold DEL when your computer is starting up, then navigate the BIOS menus to change what you want!

thanks I will def try changing it tonight and let you know how it goes
