If it's Green Performance Mode it's likely a power-saving mode, not an overclocking mode.
H67 boards were not made for overclocking. If you wanted to overclock the CPU, you chose the wrong board. The only thing you can really overclock is the processor graphics portion, and if you're using a discrete graphics card that doesn't do you any good.
A listing of what your hardware is might be a bit more helpful than your last combative post, frak.
Edit: By the way, reading the mainboard manual does wonders, frak. It would likely tell you what Green Performance Mode does.
