Fast Ram Compatible With Mobo

I have an ASRock Z77 Extreme4 and I was wanting to upgrade me ram. i currently have 2 x 8GB Samsung DDR3 1600 (http://www.newegg.com/Product/Product.aspx?Item=N82E16820147096) and i wanted to upgrade to faster ram like Kingstons HyperX Beast (either 2133 or 2400). My motherboard says that it supports 2400(OC) and 2133(OC). Does that mean I can use the beast or can i only use memory like 1600 then overclock it myself?

Why do you want faster RAM.

But to the point, there should be a list of RAM on the website of your mobo with aproved RAM.

yeah, i think  you can use the beast, but you gotta set the speed manually
