Overclocking Intel Seattle SE440BX

I need help changing my FSB on this mobo i can change a jumper and change the clock speed to 450 but when the system is running its still 350 mhz. I cant find a program to download that works with this board is there anyway to access hidden features in the bios? It has a pheonix bios. If anyone knows of anyway to overclock this mobo help me out. Also is there anyway to change the clock multiplyer?
Here is some system info.
