    GPU clock stuck when power plugged in.


      Good afternoon, I have a problem already some time that when I play games (in 3D) and the computer power is plugged in, the clock of the GPU gets stuck in 400mhz and VRAM at 600MHz, while the computer is connected only with the battery the GPU clock is 975mhz (maximum speed) and the VRAM at 900MHz, should not be on the contrary?


      I've tried several ways to figure out, uninstall the drivers for amd in safe mode, install only beta drivers, pass the windows 10 to windows 8.1, disable ULPS in afterburn and windows registry editor, put the computer to maximum performance as much as in windows as in crimson driver and catalyst center ...


      I do not know what to do, does anyone know how I can fix this?


      my computer is hp pavilion 15 n004sp

      cpu i3 4005u

      gpu amd radeon hd 8670m
