Can someone help me find a cable that will be compatable for me over 60hz?

I'm running SLI on two Zotac 1080ti'sinto my Predator X34 monitor, but I can't get over 60hz with the default HDMI 2.0 that it was shipped with. Can someone link me a compatible cable to help?

DisplayPort 1.2 should do 100Hz @ 3440x1440
