Allows you to change the multipliers on the cpu, which allows you to retain the same bus speed while clocking the cpu higher.

Boy Im realy new, I thought that the multipliers and fsb all could be changed thru eather the mobo bios or the built in jumpers.

For Intel they are "Multiplyer locked". But AMD use to sell "Unlocked chips" that would allow you to tell it to run (through the motherboard) at higher than advertised multiples. This is something a locked chip can't do.

Where as Intel's chip locking has never been over come by anyone. AMD made the chip unlocking process pretty easy. But then with the new chips it got a lot tougher, but still doable.

If you can't (Intel chips) or don't (AMD chips) unlock a chip allowing it to run at a higher multiple when the motherboard tells it to, upping your multiplyer won't get you anywhere.

If you don't want to perform minor surgery on a chip to unlock it, you can still overclock through the FSB, but your PCI cards and RAM will be overclocked as well, sometimes so greatly as to not function properly and really overheat, this is a danger for your CPU as well

So Motherboard makers started coming out with "Overclocking" motherboards which would allow the chip's MHz to be increased without increasing the FSB cards and RAM nearly as much. Thus running the PCI bus at varying "Fractions" of the CPU speed.

This is a general idea of what going on.

Generaly unlocking a chip is done to increase the multiplyer and how much the chip can be overclocked. By taking the formula Multiplyer x FSB + Cpu voltage for every 100mhz increase= you recive the desired amount of overclock- (heheh sould like bs- hummm guess i was listing in math today........)

I'd just hang in the forums for a bit give yourself a chance to get up to speed. Play with your front side bus and learn a bit about proper cooling and temps. It's not hard just takes a little getting use to":O}

Wouldn't this be best served under the AMD Mobos and CPU forum?

That's good advice, one day all these terms and concepts will click, just keep studying up and you'll understand it (like any subject, practice makes perfect).
