RX480 - "Display driver amdkmdap stopped responding" while gaming


Recently, my computer started freezing unexpectedly while gaming. Game freezes, sound continues, screen goes black, and either the game unfreezes or goes to desktop. The only error (warning) I see is in the Event Viewer : "Display driver amdkmdap stopped responding and has successfully recovered". Most of the time, the first freeze happens within 5 minutes of gaming. "Grim Dawn" is an example of a game I have played for over 200 hours without any issue, but now getting freezes.

PC specs :

  • GPU: Sapphire RX480 4GB
  • CPU: Intel i5-6600K
  • PSU: Corsair SF600
  • Motherboard: Asus Z170i Pro Gaming
  • OS: Windows 10

Things that I have tried :

  • Reverting AMD Driver to 19.2.2. using DDU (same issue so reinstalled latest recommended version)
  • Updating BIOS
  • Reinserting GPU into Motherboard slot, and changing PCI-E cable
  • Undervolting GPU and setting power limit to +50%
  • Memtest86
  • Some stress tests (OCCT, Furmark, Heaven)

As you can see, OCCT GPU 3D test has detected multiple errors, but there is no detail. Temperature seems to have capped to 80°C.GPU_OCCT.png

On the other hand, CPU stress test shows no sign of errors.



I have read multiple threads where people are having a similar issue, but no solution has worked for me.
