g46 is only part of the model of your motherboard. It should say MSI-XXXX G46 without the other part it is difficult to assist you. You should be able to overclock your processor in the bios screen by changing the multiplier and or frequency. But, from some reviews I have seen the MSI G46 (and this depends on your specific model) was VERY difficult to overclock. Feel free to respond if you have more info, such as the complete model number of the motherboard.
