Display 4k at 60 hertz

[SquattingFox]

I have 2 4k displays both running at 30 Hz. It looks to me through research that the apple software doesn't not allow you to run 60 Hz.
I am running a Display port as well as an HDMI 2.0 rated for 4k @ 60. (link here)

Does anyone have a work around for this? Is 6oHz possible? Comp stats below.

MB-SABERTOOTH-Z97-MARK 2/USB3.1
INTEL CORE I7-4790K 4.0-4.4GHZ 8MB 1150
NVIDIA GeForce GTX 980
Dual 27" ASUS PB287Q

No I tried it with ResXtreme 2 and it worked great for my one monitor. The other one still wont give me an option for 60

Saw a post hear with a guy saying 4k60 was enabled with 10.13.4.
