dmesg kernel-4.12.4

Powerplay is not working tested on several kernels, kernel 4.12.4, amd staging 4.11, 4.13rc3.
Whatever I do the clock won't change they are stuck in the lowest value which makes my card completely useless.
I'm attaching a bios a believe is correctly signed but drm say the signature is wrong.

IMO I think amdgpu kernel module is not parsing the voltage values correctly.

I tested on Windows 7 and for Windows the bios is correctly signed.

Ok so it seems, I'm an idiot!! I was setting incorrectly
