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
