This memory kit from Patriot comes with a 4000 MT/s rated XMP profile as well as a secondary 3833 MT/s just in case your CPU doesn't want to comply.

This Viper 4 Blackout kit is also already in a good starting position for those who are looking to squeeze something extra when it comes to overclocking.
