I have spotted this post by someone and it sparked my interest in trying to accomplish this but looking for some more knowledgeable folks to break it down for me .
The post
what monitor/tv is it, does it have displayport?,
if i recall correctly the hd 6000 series has partial displayport 1.2 support but has some limitations, using the clock patcher will bypass the soft limit, you should be able to get 4k @ 45 hz with cru + clock patcher+ displayport.
you can also try the clock patcher with hdmi, but I wouldn't count on good result, make sure to have a way of getting into safe mode before attempting any patching aswell.
you can find the clock patcher here

So right now i currently have my two AMD graphics running in Dual at 1080p this is the maximum reported on my windows 10.
The 6670 has 1 hdmi 1 dvi and 1 vga output and the onboard has the same options im currently just plugged into the 6670.
I have two HDMI cables with one of them actually being a HDMI to DVI so that i could try this out.
Am i wrong in guessing i would plug one of the cables into the 6670 and one of them into the onboard and then both into hdmi ports on my tv to achieve this 4k ?
