2.1 Beta 5 (May 13th, 2021)
PX PROFILEs for all CPUs. Unlock maximum performance in low-threaded applications and games.
Fast and accurate creation of P1, P2, and PX profiles during diagnostic (only for Zen 3 and Renoir). The whole process takes about 7 minutes.
Redesigned CTR HYBRID OC. Smooth, safe profile switching. The profile switching speed is up to 62 times per second (up to 4x times more than earlier releases).
Preloading profiles. Increases CTR response rate to load changes.
The effective throtlling system for the CTR HYBRID OC allows your CPU to deal effectively with an extra heavy workload (base frequency at 1.1 volts).
Auto-recommendation of the lowest possible voltages for each profile. Allows maximum energy efficiency without performance degradation. In most cases, it is capable of outperforming PBO.
Improved Idle state.
Reading CPPC information via Advanced Configuration and Power Interface (ACPI).
Improved security of communication CTR with the System Management Unit (SMU).
CTR BOOST TESTER - whether you use CTR or Curve Optimizer (CO), you can compare the results of each core booster with advanced information (temperature, PPT, etc.).
"CLEAR CONFIG & CLOSE" - button that allows you to reset all CTR settings to their defaults.
Real-time Profiles switching statistics (PROFILES tab).
Auto-recovery after sleep. Both for HYBRID OC and manual profiles.
CALCULATE button for PX, P2, and P1. If you need to recalculate the profile, you don't need to restart the entire diagnostic process (Zen 3 and Renoir).
Windows Hardware Error Architecture (WHEA) checker for tuning process.
Improved protection against dangerous and unintentional user settings.
Automatic recovery of configuration files after a failure.
Phoenix mode has been improved (fixed "PLATINUM sample" etc.).
Independent profile system. If one profile breaks, the other profiles are safe.
Improved support for unique dual CCD 5600X and 5800X processors.
AGESA 1.2.0.1 and newer fully supported.
TO TRAY - individual button. The user can choose how to minimize CTR.
Improved logging for all modes and functions.
Rebalanced CPU quality categories (gold, silver, and so on).
CTR automatically adjusts "Holding time". No longer available to the user.
Increased CTR launch speed (up to 4x times).
CTR has driver priority. Allows it to work more efficiently when the system is under maximum load.
Reduced CTR's CPU usage.
Alt-Tab fix when CTR is in the system tray.
A simpler way to activate profiles (no saving required).
Numerous minor bug fixes.


2.0 Beta 5 (March 8th, 2021)
Lower reference frequency values for Zen3 (extra safety when pressing the TUNE button)
The number of attempts to contact the SMU is increased from 5 to 10
Testing Mode - only AVX Light (fixed a bug where it was possible to unlock this switcher)


2.0 Beta 4 (March 4th, 2021)
Using RC4 is recommended. CTR's protection system now controls not only its own processes but also all processes that take place in Windows. If you deliberately try to corrupt the processor, you won't succeed.

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.


2.0 Beta 3 (February 3rd, 2021)
Support for Ryzen 5000 Series (X processors)
Support for Ryzen Renoir (AM4)
Updated Tuning and Diagnostic modes
New Monitoring (No longer needs Ryzen Master)
Phoenix feature (Restores the operation after reboot or BSOD)
CTR HYBRID OC (Utilizes both, manual OC and PBO simultaneously)
Initial Frequency Smart Offset 2.0
Improvements in software perfomance and safety
Improved profile management
