How to overclock my iGPU?

[Astralogic]

Hi, I have a 4770K and would like to overclock the igpu to see what performace improvement I can get from using it to record/stream etc.

I have IXTU, I assume I just increase the Processor Graphics Ratio Limit and Processor Graphics Voltage slowly?

Edit: And I don't know what the voltage offset slider is for :/

If it doesn't perform well enough as is, you won't get it to run much better. All you can do is overclock the CPU and your RAM. The better solution is to get a graphics card.
