    Flashing colors R9 390




      I've recently bought a new Sapphire R9 390 Nitro. The screen starts displaying flashing colors under load after a few minutes. This only happens in games and stops when I quit the game. I have reinstalled my drivers a few times already but that didn't help at all. The GPU is not overclocked. I can play LoL and CS:GO just fine without any problems.





      Windows 10 Pro (64 bit)

      Crimson Edition 16.1.1 Hotfix

      Intel Core i7 4770

      Sapphire Radeon R9 390

      Asrock B85M Pro4

      Cooler Master GM G750M (750 watts)

      8GB RAM

          That looks like it could potentially be a faulty GPU, but here are some things you can try first of all.


          How is the GPU connected to the monitor? Try using a different display cable and a different display connection on the graphics card.

          Try a different power supply. Perhaps yours is failing when put under heavy load but working fine under lighter loads, LoL, CS:GO etc.

          Try underclocking the core and memory to see if that reduces the artifacts.


          Download DDU, extract it and run it. Follow the prompt to restart in safe mode and then click Clean and Restart. You can download DDU here.


          Try reverting to Catalyst 15.11.1 Beta.

              The GPU is connected to the monitor over HDMI. I have also tried to connect it with DVI but I had the same results. I can't really test another PSU but I bought this PSU with the GPU so it is around 1-2 weeks old. Catalyst also didn't fix the problem. It's artifacting less than when I tried the card for the first time. The artifacting seems lower on ultra and low settings but gets worse if I set it to high/medium. When V-Sync is turned on the artifacting is happening less frequently aswell.
