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.


  • GPU: HD 7950
  • OS: Windows 10 64bit
  • Driver: 17.12.1 Adrenaline
  • Displays: 3 displays, one 720p television, one 144hz 1080p monitor, and a vertical 1680x1050 monitor.
  • CPU: Phenom ii 720 black edition
  • Motherboard: Gigabytyte GA-MA790XT-UD4P
  • PSU: Silencer 750w 80+
  • RAM: 8gb ddr3, 1333mhz mixed


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.
