Generally not much, unless you're using the integrated graphics.
So even if you have a ram like Crosair Vengeance which have a speed of 1600Mhz you do at all other than if you have onboard graphics?
I'm not sure what you are trying to say with that.
If you are using a discrete GPU then you might see 1-2% performance increase in gaming, and maybe a 5-10% increase in certain memory critical operations, (high end maths and analysis etc.).
if you are using an integrated GPU that uses your RAM, then you might see 5-10% improvement in gaming and 5-10% in the same memory critical operations.
So for serious gamers there is no point in overclocking memory
For Benchmarkers there is a point.
