Does anyone have better performance on old version of AMD drivers than the latest ones? Or is that a thing of the past?
Did you set radeon settings to performance rather than balanced? Balanced setting will screw with multiple cards. Did you lower intensity in crimson? Not all cards are made the same, even if its the same card. Also, did you purchase new from store or used? Someone could have modded the bios and thats why you read them differently at "stock" settings
Actually I uninstalled all those settings and only the driver remains... Maybe I should do a clean reinstall. Do most people just install drivers or the whole package with Wattool, Settings, etc...? All of my cards are new.
Do a clean uninstall with ddu, reinstall latest crimson. You dont need ReLive part of crimson install. Once its done and restarted, Right click the little crimson tray icon to make sure its set to performance. You could flash your bios, not sure what settings you want with your cards (make sure you save original bios rom though) or just try to lower intensity on core clock and up memory clock with wattman.
