I have so far been unable to find much pertaining to overclocking and overvolting on linux with amdgpu. I did find some informtion and had overclocks about a year ago but have lost the scripts. More recently however I have only seen mostly non-functional tools and going by the documentation found here: the interfaces dont seem to work the same and I was unable to see the date for the documentation and suspect it is out of date for the current drivers I am using (20.45). But utilising "echo 's 2 2020 1200' > pp_od_clk_voltage" returns "Invalid Argument". I was wondering if someone had upto date information regarding the amdgpu library and the powerplay features.
While I have found a solution to the previous problem I seem to have created a new problem. For anyone with the issue of being unable to overclock I would recommend checking out CoreCtrl. But with the new issue it seems irregardless of my ppfeaturemask and clocks set when ever I turn of the display the amdgpu dkms fails with a dmesg error "flip_done time out". I am seeing if anyone is aware of this issue.
A large portion of the last issue seems to have been related to kernel 5.11 and the drivers present there, but there is an ongoing thread on Reddit at this address:

I found the archlinux AMDGPU page quite useful for this though a little dated. They have some links to various tools the most useful of which I found to be , which is a handy script for doing what you want along with having some useful pointers in the readme.
