I am currently running an HD 7950 on windows 10 using the latest adrenaline update,17.12.1. I am running multiple displays. Relive isn't installed.
When running at stock clocks everything runs as expected, however after applying any change to the GPU clock or memory clock my screen begins to flicker/shake uncontrollably when not running any 3d programs on my desktop. What's odd is when I run any kind of 3d application, furmark for example, all flickering in desktop stops and it runs just fine. After monitoring GPU clock speeds it seems like the GPU doesn't know what to do outside of high performance mode and the clock speed drops from my set overclock (anything other than 925mhz) down to 300mhz and the memory clock drops to 150mhz. Does anyone know of a work around such as locking the GPU in high performance mode? In the meantime I'm probably going to be reverting back to an older driver.
Similar issue with rx Vega 56. 3-1440p displays and an i7 7700k. Any attempt to overclock even the tiniest amount results in display driver crashing or locking up, requiring hard reboot. Rolled back to 17.11.1 as I had issues in 17.11.4 with overclock as well. 17.11.1 works great hopefully they can find the problem quickly id love to take advantage of the new features in adrenalin
