1usmus has announced the official release of CTR 2.0 (Clock Tuner For Ryzen) which comes with AMD Ryzen 5000 'Zen 3' CPU support and a handful of new features to maximize your gains with the latest processors that AMD has to offer.

1usmus's CTR 2.0 (Clock Tuner For Ryzen) Adds Support For AMD Ryzen 5000 'Zen 3' Desktop CPUs, Now Available For Download - Includes Hybrid OC & Phoenix Modes, Several New Features & Bug Fixes

The Clock Tuner For Ryzen has finally left its v1.* variation and entered the V2.0 release with CTR 2.0. This major update finally adds support for AMD Ryzen 5000 CPUs based on the Zen 3 uArch. According to the release log, the update brings the following highlighted features:

NVIDIA: ARM Chips Can Almost Beat x86 Processors, A100 GPU 104x Faster Than CPUs

  • Support for Ryzen 5000 Series (X Processors)
  • Support for Ryzen Renoir (AM4)
  • Updated Tuning & 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 & PBO simultaneously)
  • Initial Frequency Smart Offset 2.0
  • Improvements in software performance and safety
  • Improved Profile Management

CTR 2.0 (Clock Tuner For Ryzen) is available to download through the following links:

Starting with the changes, the CTR 2.0 update brings a new graphical user interface that offers dark mode support and blends in with a more modern UI. The whole interface is now more streamlined and looks cleaner than the previous versions. However, the main feature to talk about aside from the addition of AMD Ryzen 5000 Zen 3 CPU support is the new Hybrid OC feature.

According to the data shared by Yuri, the Hybrid OC mode is a combination of custom profiles and auto boost which means that users won't have to worry about choosing between standard boost & manual overclocking. Hybrid OC mode has two main profiles, P1 and P2. The P1 profile is designed to offer the maximum all-core boost while the P2 profile maximizes gaming performance by tuning the CPU to offer the maximum performance for a singular and best CCX (or multiple CCX). Both of these profiles can also be configured manually by users themselves.

In this picture, the standard boost frequency is marked in red relative to the number of cores used. Also, in this picture, I see P1 and P2 profiles, which I got during troubleshooting and tuning. I managed to gain 200 MHz for all-thread load, and for 6-thread, I got around 200 MHz with the same power consumption. The actual Cinebench R20 performance has grown from 4289 to 4616 (+8%) for 12 threads and from 2842 to 3144 (+10%) for 6 threads, leaving the single-thread performance unchanged. It looks impressive, doesn’t it? Anyway, it’s up to you to judge.

In performance benchmarks shared by Yuri, Hybrid OC manages to offer up to 10% better multi-threaded performance and identical single-core performance which means there's no loss in the overall single-core perf when tuning multiple CCX's. The profiles also don't break past the TDPs set by AMD as default and hence this feature actually helps improving energy efficiency for AMD Ryzen 5000 Zen 3 and also Ryzen 3000 Zen 2 CPUs.

In another benchmark with the AMD Ryzen 9 5900X, 1usmus demonstrates a 7.5% gain in content creation performance within Cinbench R20 with the same levels of power consumption. The under-volting feature is also supported and the chips can offer the same amount of performance with a massive 28% reduction in power consumption. Finally, we have the new Curve Optimization feature that was demonstrated using the Ryzen 9 5900X CPU too. This feature is kept for manual tuning for now but auto-tuning will be added within the CTR 2.1 release.

There's also the new Phoenix mode which lets users continue with fine-tuning their systems where they left off. In previous versions of CTR, the CPUs crashed during auto-tuning and there was no proper recovery system in place. Users had to manually go through the logs to recover their configs but that changes with Clock Tuner For Ryzen 2.0.

Other features for the CTR 2.0 (Clock Tuner For AMD Ryzen CPUs) include:

  • New Monitoring - has the highest response time of all existing monitoring programs: 1ms in
    idle and 7ms in all-core load mode. Does not requires AMD chipset drivers. Additional
    information about processor telemetry, the temperature, and the VID of each core (Zen3).
  • Phoenix feature —BSOD or reboot happened? Worry not! CTR will automatically recover and
    will finish the diagnostic or profile creation. If necessary, it will test in Cinebench R20 as well.
  • Initial Frequency Smart Offset 2.0 - diagnostic mode will predict the recommended
    frequencies more accurately, so you can significantly reduce tuning time. Important for AMD Ryzen 5000 processors that have 4 and 8 CCX. The evaluation is based on dynamic FIT, not static data.
  • Improvements in software performance - most of the code has been rewritten. CTR now uses
    less CPU time, particularly when minimized. Special attention was paid to safety when
    communicating with SMU.
  • Diagnostic mode now provides information about the basic coefficients of the voltage curve
    (Zen 3) as well as information about the values that are recommended for Pl and P2 profiles.
  • An advanced logging system allows you to create a logbook individually for each CTR startup.
  • Improved profile management system for more comfort.

1usmus has also released a roadmap for his CTR utility for 2021. Also in the first quarter of 2021, the utility will see the official v2.1 release (currently in early access) which will add Auto Curve Optimizer & CTR Hybrid OC 2.0 modes for AMD Ryzen 5000 Zen 3 CPUs along with a new measurement mode and additional optimizations for Zen 3 based chips.

In Q3 2021, CTR 2.2 will be released with support for AMD Ryzen Threadripper 'Genesis' CPUs and will also add support for Ryzen 5000G 'Cezanne' APUs.
