Hi folks, i have a fix for the black screen issues, weird freezes and even artifacting onscreen to a total crash of the gpu.
It's all about your gpu temp.
The main problem is the amd radeon default fan control settings and temps when they supposed to kick in.
The way they work now is when they reach 80 degrees the fans start to kick in and not even at 100% fan speed, but by the time they start cooling down it's all ready to late, resulting in a crash, black screen or artifacting onscreen.
Go to radeon performance and set your own fan control settings, make sure your fan runs at full speed when it reaches 58 degrees, and set fan noise control to max, lowering fan noise control makes the fan kick in at a later time overruling temps and fan settings, so setting this to max 100% will make sure your gpu gets the cooling it needs.
Save it as default.xml or any other name you like, and make sure when you update your drivers you need to apply the defaultl settings again, so keeping a backup of your default.xml on your harddisk is recommended.
One other thing based on freesync is to change the voltage swing and preemphasis under display overrides, especialy when you use hdmi/displayport cable longer then 1 mtr, it will sure help.
I have been testing with these settings for a whole year now and had no issues, unless the radeon software and drivers got updates and i forgot the apply my default fan control/noise control/override settings again, the whole black screen freezes and artifacting came back.
A note to amd, change your default fan control and noise control settings, they are the cause of the black screens people are having, and a note to all of you the default settings is gpu breaking, and eventualy will result in total failure of your gpu card when you do not change your fan/noise control, your card will fail due to high temps and wrong config on default fan /noise control settings.
Don't mid the typos
Update; added some snapshots radeon default delivered by amd note the fan speed when it reaches 85 degrees and noise control at half causing the gpu get hotter then it can handle around 90 degrees and still fans wont reach 100% speed.
Custom the way i have set it up now making sure it does not go beyond 75 degrees, now when heavy gaming temp are around 72 to 75 degrees with fans at max speed and noise control at max to let the fans kick in when it needs it.
