I was using an overlay while gaming for CPU and GPU numbers. Temps are fine, usage ~60 for CPU, 80 for GPU. I can't find the culprit, maybe I need to monitor/log the clock voltages?
Both temperatures are around 67C, so no worries there. Windows is around 1.5 years old. I just installed the driver with DDU because I come from Nvidia. But I will check the chipset drivers
It was not a problem with the 1080, albeit with way lower settings. It's 4x 2666mhz ddr4
