I've tried the new CRU (v1.2.3) and changed the range from 30-75 to 30-85 and even just doing this prevents FreeSync; this is without even creating a new 85hz option in CRU.

Any ideas?

I don't have a FreeSync monitor, so I don't know what's required for FreeSync to work. The only document I found from AMD says the EDID must indicate that it is a "continuous frequency display" and report the range of refresh rates that the display supports, which is what CRU does when you include the range limits descriptor. The FreeSync "hack" is just modifying the range limits descriptor with an EDID override like CRU does, so I don't understand why it's not working.

Did you make sure to include the range limits? It should show in the detailed resolution list. CRU doesn't include the range limits by default so you have to enable it.

If that's not working, run reset-all.exe and restart.exe. Then use MonInfo to save the EDID to a .bin file and post it here. I want to see if there's anything else that might be required.
