Overclocking

Hi guys
I've decided to sing up on this page because I don't know what to do anymore!
I was hoping that you would help me!
My problem is next :
I Have Intel Celeron Dual Core E3400 2.60 GHz with Intel G41 Express Chipset 1582 MB and 6.00 GB DDR3-1333(667 Mhz) and I would like to overclock my CPU
but in BIOS i don't have overclocking option because i think that it's disabled to prevent it.(and I've upadated BIOS but still no option ) Then I've tried with Clockgen and Asus Evo and lots of other programs but they ask me to choose my PLL and I know what my PLL is but none of programs that I've tried doesn't have my PLL to select so basicly I'm screwed! If anyone can help I would be pleased

If you cannot find your PLL to use with Clockgen/SetFSB, then you are screwed. You would need to purchase another mobo to overclock.

That's what I've thought. Thx anyway mate
