Mine was fine and stable for awhile but again last night it crashed while playing F1 2019 and stopped showing GPU temp and fan speed and caused a crash which then locked up my monitor and wouldn't show anything at all until I unplugged the monitor and rebooted again.
And now it's ok showing temp and fan speed until I start up F1 2019 again and it stops. You can literally see in the performance graphs where it stops showing the data and then starts again as soon as I close F1 2019.
I'm almost at the point I want to return the card and go to Nvidia. I have until today to decide and cancel my waterblock order with EK for the 5700 XT.
Hey. The exact same problem (the sound on hdmi also breaks). I have a 1440p monitor and a refresh rate of 75 Hz. I noticed that if you set the refresh rate to 60 Hz, then everything works fine. Or if you connect a second monitor with 60Hz. I'm really starting to think that this is a video card problem, not a driver issue.
