It works but, as I've said on SMOS thread, using roc kernel and changing boot parameter makes power consumption goes from 1150W to 1550W (on the wall, at least on my rx580 rig). Have you checked your power consumption after this change?

I use roc kernel on smos and consume it is the same, maybe you changed power step (consume is setup at level of bios of gpu, i have steps from 2 to 7 to my target voltage), check them on console.

I've followed these steps:

wget -qO - http://repo.radeon.com/rocm/apt/debian/rocm.gpg.key | sudo apt-key add -
sudo sh -c 'echo deb [arch=amd64] http://repo.radeon.com/rocm/apt/debian/ xenial main > /etc/apt/sources.list.d/rocm.list'
sudo apt-get update
sudo apt-get install rocm

#edit grub
sudo nano /etc/default/grub
#2MB fragments for Ellesmere are enabled with a grub option:
GRUB_CMDLINE_LINUX="amdgpu.vm_fragment_size=9"

sudo update-grub
sudo reboot

And I haven't changed bios, oc parameters,... So, I have a few questions:
- how to check these power steps on linux console?
- how to change them?
- my power consumption at wall were too high also before change (4x rx580 @ 1150W at wall) with smos (oc 1175-2250 dpm state 2). what about yours?

Thank you in advance
