You do, but also kep in mind that it's base frequency is 4.2GHz (it does not turbo). So you might not need to overclock and you might not get much overclocking out of it. Also the more heat and power you are using on the CPU side the less performance you can get from the iGPU with out running into power\thermal throttling if your cooling and your board's power delivery is not up to it.
