Overclocking or modifying AMD graphics cards under Linux?

Besides our MorePowerTool and the RBE (Red BIOS Editor), as well as the required third party files for flashing the supported BIOSes under Windows, there is now a very elegant method for Linux. Patrick Schur has published AMD's mysterious atitool on Github and recently updated it again, so I don't want to keep it from you, also to round off our own tools.

Even if Linux seems a little more niche, users with Radeon cards are not a small minority. And since the AMD drivers under Linux actually do exactly what they are supposed to do, namely work, such an opportunity to manually modify the card itself is ultimately more than just a nice bonus from the community.

You don't necessarily have to overclock the Radeon cards, but can also make them significantly more economical and even more stable. In this respect, the feature set of the atitool reads like the menu of a fine restaurant with a chef's menu:

  • Clock and Voltage management
  • PowerPlay support
  • Device information and status reporting
  • I2C operations off GPU
  • MC control/status
  • GRBM soft reset
  • PCIE control/status
  • Serial ID reporting
  • HDCP A-Key reporting

In contrast to the Windows tools, which we host and update ourselves, Patrick organizes this via Github and takes care of the file maintenance there as well. Because Patrick can't offer support at the moment due to time constraints, I would like to refer to the forum and the linked thread.
