CTR (ClockTuner for Ryzen) software allows each user to customize the system with maximum energy efficiency. In this case, CTR is fully automated and does not limit the user in actions. The program has a kind of artificial intelligence, which will help in any situation, and the protection system will monitor each step so that your components were not exposed to danger. CTR is compatible with all motherboards on the AM4 socket, despite the artificial limitations of AMD. As for conditions, it is probably one thing - the processor should be based on ZEN2 and now ZEN3 architecture. CTR is made by Guru3D's oldtimer 1USMUS.

Please read the original v1 guide before usage on how to use and setup ClockTuner for Ryzen., seriously do that. We also have an updated guide based on v2.0 that you can read here. Our discussion forum on this topic can be found here.

What's New:

  • Updated driver. Full compatibility with all anti-cheats. Full compatibility with Ryzen Master.
  • The response speed of profile switching has increased by 5 times. The 1 cycle time is now 50ms.
  • HYBRID OC redesign. More stability and smoother profile switching.
  • Automatic acceptance of the Cinebench R20 license (less user actions before you start working with CTR).
  • Improved security of CTR and processor communication.
  • Improved protection against dangerous user actions (from forced attempts to interfere with CTR processes).
  • Improved support for unique dual CCD processors (5600X, 5800X, 3600, 3600X).
  • Updated PROFILE MANAGEMENT. Multifunctional buttons, simpler interface (PROFILES tab).
  • The CPU category (Gold, Silver etc) is now protected from "LLC cheaters".
  • Redesigned LLC tips.
  • Added tips when entering data incorrectly for profiles.
  • Profile status. On PROFILES and TUNER tab you can see which profile is currently active.
  • Fixed visual bug of high VID or high TEMPERATURE.
  • Fixed random crash when using HYBRID OC.
  • Fixing other minor bugs.

For correct work, CTR is necessary:


  • Download CTR and unpack the ZIP archive in a directory of your choice
  • Then download the Cinebench R20 archive and extract the contents of the archive to the “CB20” folder (this folder is located inside the CTR folder).
  • You can now run the Cinebench R20 one time. Please accept the license agreement, and close it Cinebench R20. CTR is now ready for use.

The main principle of this software is to evaluate the quality of each CCX and adjust the frequencies individually. Prime95 with a number of special presets assesses the stability of each CCX. A step-by-step frequency algorithm with multiple rules allows you to select the most stable frequency for all CCX simultaneously without disturbing the energy balance between the CCX. CTR also contains a plug-in (optional) test package Cinebench R20 from Maxon, which will evaluate the results of the tuning.
