Below you can read how I did it, what I achieved, metrics and some other stuff. Just recently I read somewhere that you have to edit registry files, in order for MSI afterburner to work properly with Radeon cards, where as with nvidia cards, all you have to do is change the value in the Config file.Out of scientific curiosity, I tried (and succeeded) overclocking the Radeon Pro 575 on my iMac 2017 2.5 GHz 27”. Now, no matter how little I went over the factory allowed 840/1350 I would get crashes or major instability. It allowed me to do this in both MSI afterburner and CCC, so the MSI program kinda went backdoor into the CCC and edited the max allowed OC values. Now, I remember having to go into a Config file, change some value from 0 to 1 and paste some sentence in there stating I knew the risk I was taking, blah blah blah.Īfter doing this, I was able to push my values from 840 up to 1000(never tried going that high) and something like 1350 to 1500(not sure). When I went to edit my values, they would not go past the factory allowable overclock settings that were in the Catalyst Control Center which are 840/1350 mhz respectively. A while back, I downloaded MSI afterburner.
