How Do I stop My V-Sync and how do I turn On The Overclock

Hey everyone, 

I have this new Helios 300, like 2 months or so and I was wondering how do I stop My V-Sync. And yes, I tried to do it in the games I've been playing, but the fps never goes up or down. It always sits at 244 fps. I thought it may be something in the laptop settings and I don't know.

Also, on YouTube, on a video posted by Predator Gaming, at the presentation of Helios 300, the guy has the Overclock Menu there, in Predator Sense, thing which I can't find in mine. I can only find my Monitoring Menu and of course the Fan Control.
