--- Comment #3 from Vittorio vittorio88@gmail.com --- I can confirm the issue.
I have tested on Ubuntu 16.04.2 and 17.04. Both give the same results. 17.04 as of today uses kernel 4.10.0-33-generic #37-Ubuntu.
I am using Radeon Rx470 for testing.
I can successfully overclock memory on Windows.
Many other people have this issue on amd.com and phoronix.com forums.
I do not believe I have run across a single instance of this working across many forums where I have investigated.
I am willing to provide further info and testing if required, and have placed myself on CC.
Thanks, Vittorio
