Guys...how do I unlock my multiplier? on my Pentium 4? This might sound like a stupid question, but I seriously don't know how to.

it's locked at 18x (18x111 = 1997Mhz (2Ghz))

does a lower multiplier and an increased front side bus raise your performance?

If the CPU frequency is locked there isn nothing external you can do to it with FSB or multiplier settings. There are modifications that can be physically made to some CPU's to unlock them but if you mess it up you have a worthless piece of silicaon.

Most of the newer boards these days are jumperless and they just autodetect the cpu speed and intentionally lock u out of changing the speeds because they dont want idiots frying their processors because of overclocking. They figure that most people are to dumb to set these options on their own so they do it for you. Most old boards had jumpers or dip switches on them that would allow you to change the multiplyer manually. Now days its not as easy and like someone explained there are ways but unless you really know what you're doing you're risky frying your cpu.
