PowerColor Red Dragon RX 5700 XT crashing

Question asked by dawheeler on Apr 30, 2020



I purchased a PowerColor RX 5700 XT Red Dragon, 10 days ago. From the very first time, I had issues. During gameplay it crashes randomly, after 2-20 minutes (APEX, CoD: Warzone). It is very strange that the crash appears only during gameplay and when I try to over/underclock but not during benchmarks like 3D Mark or in any other load/stress test. Green screen appears for a second and the computer restarts itself. The problem almost immediately appears if I press alt-tab during game. After the first crash, the next one will almost immediately occurs after I start the game.
What I tried so far: 
  • Clean windows install (Window 10, up to date)
  • AMD chipset and Ryzen Master install
  • Bios update
  • Checked that PCI Express is in version 3
  • Tried multiple AMD drivers (even the popular most stable ones)
  • Tried to undervolt
  • There is nothing useful in event log
My configuration: 
Power supply: Chieftec Smart Series 700W - GPS700A8
Motherboard: Gigabyte Aerous Elite B450
CPU: Ryzen 3600
Memory: 2*8GB DDR4
Any suggestion is appreciated.
