I finally figured out the solution. One thing I have never cared for with this GPU is it’s cooling setup. It has a big heat pipe type cooler and a pair of 90mm fans. In the default settings the fans only work when needed. The average temperature was 50°C (122°F) it never dropped below that even in idle. According to the gaming forums that was more or less a normal operating temperature. To me that seemed rather high I keep my FX9590 at less than 30°C (86°F) I finally figured out how to take manual control of it’s cooling fans. The fans showed a speed of less than 400 rpm in Automatic. In the Radeon connsole => Gaming => Global Settings => Global Wattman, scroll down to the fan controls you will see speed (RPM) click on the manual control. I increased the fan speed to bit more than 1700 RPM. Noise is not a factor, My Corsair 750D full tower has 3 140mm case fans that run at 1500 RPM. The liquid cooler has a pair 140mm fans also running +/- 1500rpm so 2 more 90mm fans running at 1700, or so, rpm is not going to add much to that. All of the fans are very quiet anyway. Now the GPU is running at less than 38°C (100°F) no matter what the load is, and I have not been able to trigger a freezing incident since going manual, and I have tried very hard.
