Yuri Bubliy (1usmus) has released a new version of his popular software tool, Clock Tuner for Ryzen. The latest rendition, version 2.1, allows Ryzen 5000 Series owners to easily and safely boost their Zen 3 processors all the way to 5.0 GHz by leveraging a new “PX” profile that is 25 mV lower than the standard voltage (1.45 vs. 1.475 V). It provides a stable, fixed, and effective frequency that isn’t affected by any limits—no EDC throttling, temperature throttling, or stretching.

We’ve copied the main improvements that come with version 2.1 of CTR below, but you’ll also want to check out Bubliy’s slides for other specifics, such as a redesigned profile system with new functions and usability updates. Bubliy has also shared a video demonstrating how the new PX profile works.

Clock Tuner for Ryzen 2.1 Features

  • CTR will automatically find the best cores for PX PROFILE during the diagnostic (for AMD Ryzen 5900X and 5600X-4 maximum, for 5950X and 5800X — 6, and for Zen 2 — 2 temporary maximum). There is no increase in diagnostic time. You will see the result on the PROFILES page.
  • CTR will automatically set the frequency for all recommended cores (it also happens during diagnostics). All other cores that are not in the group will run at a reduced frequency. Due to this maximum stability and fault tolerance are achieved.
  • Since the processor very often works with a combined load of 1-6 cores, a high speed of load evaluation is needed to switch profiles as accurately as possible. Depending on the current operating profile, the sensor polling rate also changes. PX PROFILE is the most sensitive, the sensor polling period is every 150ms (for P1 — 250 and for P2 – 200).
  • The updated HYBRID OC has a reduced profile activation time. For processors with 6, 12, or 24 cores P1 or P2 activation time is reduced by 30%.
  • Updated priority system. P1 PROFILE has a higher priority than P2. P2 PROFILE has a higher priority than PX. This makes it possible to avoid frequent or false profile switching. It also allows you to significantly reduce the temperature of the processor.
  • PX PROFILE has holding settings just like the other profiles. This will avoid a false shutdown of the profile if the load on the cores is pulsed.
  • If the current TDC value is lower than the TDC trigger (A), PX PROFILE will automatically be disabled and the AMD Ryzen 5000 processor will go into standard boost mode. That is, in this mode the maximum power saving is maintained.
  • Improved security. While HYBRID OC is running, CTR will monitor the current-voltage. If this value exceeds 1.525V- CTR will automatically restart the system without user confirmation. I believe that some users may ignore the instructions, so I have updated the rules for the security system.
  • Checking stuck sensors. There are situations when a sensor stops responding. At this point, the user may see an abnormal temperature, frequency, or voltage value. I have implemented a system that analyzes the state of the sensor.
