Hi from a newbie in the UK. My first post, a question about putting a faster processor in a Compaq ipaq light legacy desk top pc Pentium 3 . Currently running 100 MHz fsb and a clock speed of 500 MHz stock frequency. I want to know can i run a 750 MHz cpu 133 fsb on the same motherboard, will it work ? is this under clocked ? will the memory / Ram need to be the same ? i really don't wont to over clock the motherboard fsb to keep up, some loss of speed due to the multiplier i can live with, so in a word will 133 MHz fsb processor run on a 100 MHz fsb motherboard. So much conflicting information on the web from searching this. Thanks for looking any help appreciated. :)
