I got it to hit 75hz with the driver patch. Do DVI monitors have a scaler? I am trying to enable freesync with a range of 55-74hz (monitors spec sheet says its range is 55-76hz vertical).
I used the HDMI block OC'd to 660MHz along with the freesync module but after a reboot the driver still detects the monitor as DVI-D not HDMI. That means it wont allow the freesync option to be available. There are other AOC monitors with 2460 in their model number that support freesync at 75hz. They have the same panel as mine. Is there anything im doing wrong in my configuration

Any monitor with an OSD has a scaler. Getting FreeSync to work with DVI requires tricking the driver into thinking it's HDMI, which requires physically unplugging and reconnecting the DVI cable with the RX 480. This has to be done after every reboot, so it's not practical. I don't understand why you are setting the maximum TMDS clock to 660 MHz when that does nothing, or why you are including the range limits in the main window with the maximum pixel clock set to 170 MHz, which isn't necessary either and contradicts your config. You shouldn't need anything except the HDMI data block and the FreeSync data block and a detailed resolution for the maximum refresh rate.

I don't like that thread because it gives the impression that FreeSync can work with any monitor when that's not the case. Only a few monitors don't have scalers. I've only confirmed this works with the overclockable Korean Catleap/QNIX monitors. I haven't seen any proof of it working with anything else. People keep asking for help on monitors that clearly can't do it, and CRU was not intended for that purpose.

Unplugging and repulgging alsways results in it not detecting the replug. Meaning I have to reboot to get display again. I think I'll try a HDMI to dvi cable. If that fails I may just buy a freesync monitor anyway.
