Ok so i need the pll for my Fujitsu siemens G31t-m2 Motherboard but when i found it i can't find the PLL for OC in any OC software! I have also tried to search on the internet but no luck with the numbers....... I was searching below the GPu when i found it ... I haven't though found anything near the CPU..... aany tips or anyone that knows my PLL... :)

Not all PLLs will allow overclocking. The PLL chip is usually right next to the reference oscillator. The oscillator is a silver pill-sized object with numbers on the top. The numbers on it should say something like "14.318" (since the oscillator generates a 14.31818 MHz signal.) Here is a good example: http://www.cpu-cool.de/8864.jpg
