My GPU is normal at idle usage (300 MHz clock and 300 MHz memory) but after I start a game and exit it the clock speed doesn't come back at idle one.
Here's my specs:
RX 580 Red devil 8GB
16 GB memkit (tridentz) at 3200 MHz
Gigabyte GA AB 350 gaming 3
Edit : Can you help me solving this problem?
Use HWMonitor to see the min/max GPU temps/clocks
