Unable to overclock AMD R9 290 using amdgpu driver

I would like to overclock my GPU (AMD R9 290) using the amdgpu driver, but I have not found much on the ArchWiki. I read here (https://linuxconfig.org/overclock-your- … ith-amdgpu) that you are supposed to do it by setting a number between 0 and 20 for the GPU overclock percentage like this:

echo "5" > /sys/class/drm/card0/device/pp_sclk_od

or this for the memory:

echo "8" > /sys/class/drm/card0/device/pp_mclk_od

However, even when running these commands as root and without using sudo, if I then do

cat /sys/class/drm/card0/device/pp_sclk_od

or

cat /sys/class/drm/card0/device/pp_mclk_od

I still get 0.

Any ideas?

Note: Running

cat /sys/class/drm/card0/device/pp_sclk_od

does always return either 1 or 0, no matter the value added to it via echo.
