Gskill memory 2011 v3 Socket

Hey all I'm building my new pc x99 2011 v3 socket and I have a Asrock x99 2011 v3 with a 6850k but memory I'm still a little stuck I was thinking these gskill 2400 https://www.newegg.ca/Product/Produc...-791-_-Product
is this better if you are going to do a little OC or should I buy a higher speed memory?

Thanks

should be fine with 2400mhz, IRL it's not much difference with higher rams.
