Cannot overclock AMD GPU on Ubuntu 18.04 LTS
I am trying to overclock the memory on my GPU with AMDGPU Pro 18.40 driver.
Nonetheless, /sys/class/drm/card0/device/pp_od_clk_voltage is an empty file and I cannot write to it.
When I try
echo "m 2 1600 950" > /sys/class/drm/card0/device/pp_od_clk_voltage
as root it produces the following error:
-bash: echo: write error: Invalid argument
I have amdgpu.ppfeaturemask=0xffffffff in GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub.
I have also tried running:
echo manual | sudo tee /sys/class/drm/card0/device/power_dpm_force_performance_level
My question is based on the answer to the following question: Can't overclock GPU using amdgpu driver on archlinux
The author claims that this method works, however it obviously does not.

I had to install this:
https://github.com/BoukeHaarsma23/WattmanGTK
and then I ran it, and it told me the value I needed to pass to amdgpu.ppfeaturemask.
In my case on a Vega 64 the value is 0xfffd7fff
And yea you add that to grub :)
