Pi 3 won't let me overclock?

[Willreaper]

I'm trying to overclock my Pi 3 just enough to play N64 games without lag but when I try to do it the easy way it tells me I can't and I'm not sure how to get past that?

@willreaper you need to manually do it in /boot/config.txt

I used this guide for the overclocking and this was the correct method and worked for me:

Take a close look of that console image, where the lines are positioned in the boot config, that is the key thing that has to be correct.

After that, you need to try out different settings in the emulation, by opening the Quick Menu while game is running and changing the emulation options.
