No. You need Z370. Also, Even if you could do it with some hacks, B360s don't have the high-quality parts needed to sustain that OC. Just make sure turbo is enabled. I think Asus called it multi-core enhancements. You have to look at BIOS if it doesn't use turbo.

And two, if you're a gamer, you would gain more from overclocking your GPU, as the CPU is strong enough for every game you throw at it.

No. There have been claims that B series motherboards are overclockable. But the fact is they are not suited for that purpose. Both the B & H series of motherboards are stripped down versions of the Z series of motherboards. They were stripped down to reduce the selling price (basically for people that had no desire to overclock ).

If you want to overclock the processor, buy a Z370 motherboard.
