Hi. I have exactly same GPU and same problem, I thought it was something wrong with my MB but how I see it’s not. I been trying to do everything. No idea how to fix it. 100% faulty gpu
I had constant crashes until i tried using 2 separate power cables to the gpu from PSU. After that i have not had any crashes. Before that i tried fiddling with undervolting and trying out different drivers.
It works for me so try it out.
Same problem, tried changing drivers, Win10, mobo, cpu, ram, psu, ssd, hdd at no avail, but changing the PSU to a red devil 5700xt fixed it 100%.
The card is still under warranty, but due to the current shortages my dealer advised that I wait as long as possible to RMA it. Normal turnaround is 3-5 weeks, currently its more like 4-8 weeks and most cards doesn't get repaired (or replaced) but rather reimbursed. That would be useless since a similar card will cost be double if I can find it anywhere. 😞
Currently I have down-clocked the card to 1890Mhz, and the last 3-4 days I haven't had any crashes. My MW Warzone 1440p performance is down approx. 20 FPS, but at least I can play the game at around 100 FPS.
Might work for you...
