MP 1,1-5,1 Mac Pro 5,1 RX 580 Forced RGB also forces 60hz

[thewoolysheep08]

I have two ASUS VG258QR monitors capable of running at 165hz. I used to use a GTX 680 in my Mac Pro and had no trouble running both at atleast 120hz using one HDMI and one DVI to HDMI. I got my RX 580 today and tried the same setup except that the monitor using the DVI to HDMI cable showed up in all pink, i used the "patch-edid" script to force RGB on the second monitor and it worked except now both monitors are forced to use 60hz instead of atleast 120hz (what i was able to run them at before). The option to change the refresh rate is completely greyed out, i have tried SwitchResX and that doesn't work either.

What i want: To be able to run both monitors at 120hz while using the force RGB script.

Any help would be appreciated.

Make sure you only have one override for the display.
It should be stored in /Library/Displays/Contents/Resources/Overrides
Instead of in /System/Library/Displays/Contents/Resources/Overrides
