I have triple checked everything, and everything seems to be properly installed?

I have attempted to force 'amdgpu' to be the main one(by changing the modules order on mkinitcpio.conf), but:

  • It doesn't load Vulkan at all
  • If I plug the HDMI in, GFX_MCLK pegs to 100% constantly, and the fans goes to full throttle until the entire system crashes (GPU overheating?)

Okay so, I don't know what I did, but I switched to amdgpu default, GFX_MCLK is at 10%, and vulkan works
But now the DVI port doesnt work lmfao
