One of the biggest things for PC enthusiasts to do is attempt to overclock their computers to the highest stable speed possible. For the Zen 3 AMD Ryzen 5000 CPU lineup, that officially has been to overclock up to 4.9GHz for stable speeds. But now, a new third-party software update is aiming to not only reach higher speeds, but do so safely.

ClockTuner for Ryzen is a utility that promises to safely increase AMD CPU performance. Launched alongside AMD’s Zen 2 processors, ClockTuner is an automated application that makes it easier than ever to jump into the overclocking world. Creator Yuri Bubliy, also known as “1usmus,” is looking to push Zen 3 processors above 4.9GHz clock speeds with the new 2.1 beta version of ClockTuner.


The latest version of the software features a new profile setting that allows the CPU to reach over 5GHz on the latest Ryzen Zen 3 chips. In his example, he showed off reaching over 5GHz on a Ryzen 9 5900X with a lower power voltage of 1.45V. 

Can you overclock other AMD Ryzen CPUs?

According to the utility’s website, ClockTuner supports the following processors:

  • Zen 3: Ryzen 9 5950X, Ryzen 9 5900X, Ryzen 7 5800X and Ryzen 5 5600X
  • Zen 2: Threadripper 3970X, Threadripper 3960X, Ryzen 9 3950X, Ryzen 9 3900X, Ryzen 9 3900XT, Ryzen 9 3900, Ryzen 7 3800XT, Ryzen 7 3800X, Ryzen 7 3700X, Ryzen 5 3600XT, Ryzen 5 3600X, Ryzen 5 3600, Ryzen 5 3500X, Ryzen 5 3500, Ryzen 3 3300X and Ryzen 3 3100
  • APU: Ryzen 7 PRO 4750G, Ryzen 7 PRO 4650G and Ryzen 3 PRO 4350G

Though ClockTuner supports lower-end processors, it should be noted that it’s unlikely to reach 5GHz on Zen 2 chips. That said, you can get close to or at the 5GHz mark on the mid-level Zen 3 Ryzen 5 5600X.

What it gives you each time is the highest possible speeds based on the selected profile. During its initial diagnostic of your system, ClockTuner will find the best cores (up to six) for the 5800X and 5950X and automatically set the frequency for the recommended cores. On the 5900X and 5600X, the software will select a maximum of four cores, while it will select just two cores for Zen 2 CPUs.

If you are nervous about entering the OC arena, the new update will include UI changes to make it easier for new users. The new update is currently only available for supporters of the software, but a full public release is coming. If you do decide to give ClockTuner a try, please do so at your own risk. As with any third-party software, overclocking results are not guaranteed and could void any warranty you have on your AMD Ryzen CPU.
