Your motherboard needs to be able to overclock... which it apparently is... read this guide: http://www.overclockersclub.com/pages/overclock_faq/ the settings should be in the bios. As long as you don't change the vcore, you shouldn't damage your cpu. Basically, you just multiply the FSB by the multiplier, and you get your new clock speed... also, if your computer doesn't boot, and you can't get into bios, you'll need to know how to clear cmos: http://www.retrevo.com/support/MSI-945PL-Neo-manual/id/8353ag901/t/2/ just download the manual, and read it, and you should find out where the jumper is... make sure that when you clear it the computer is off, and when you put the jumper on one set of pins, you then move it back to the other set before you start the machine. Basically, the jumper shorts the circuit, so your bios return to factory defaults. Good luck!
