Your board does not support overclocking.
Overclocking is best done in the BIOS, yours does not have the options.
Software overclocking does not generally work well, but the ones that work at all (reasonably safely) are the ones that are supplied with some boards that DO support overclocking and they work only on those boards, due to built in support.
Sorry, you will need to keep it, replace the board (G43 or G45 chipset from Gigabyte, Asus, Biostar or a few others) but make sure it supports your CPU, or better, wait and replace the whole thing. In the mean time, you can upgrade your video card if you are using the stock or onboard video which will give you a significant boost, especially in gaming and graphic programs.
You have to be a little bit crazy to keep you from going insane.
