GPU: R9 390
OS: Windows 10 Pro KB4015583
Monitor: 1050x1680 60Hz, 1920x1080 76Hz, both connected to R9 390 via DVI
Problem: Overclocking( adjusting core clocks by any %(it doesn't matter) + any voltage adjustment) works temporarily but causes my monitors to start flickering after pressing reset in Wattman or MSI Afterburner. The only way to remedy the flickering problem is with a complete system reboot. I've been dealing with this for 5+ months now. The last stable driver was 16.11.5.
