An enthusiast of Reddit KBSK1 has just developed software called Renoir Mobile Tuning. The latter allows you to overclock or underclocker the Ryzen 4000 processors. It has just put online the first RC V 1.0.0 version and laptop holders hosting these processors can customize their operating settings.
Software to customize your processor
Entrepreneurs always leave tuning software for the Ryzen. Indeed, Clocktuner has been used by many enthusiasts to modify the parameters of the Ryzen 3000 series processors as they please. It is therefore now on the 4000 series. Users can use the RMT or Renoir Mobile Tuning to Overclocker or Underclocker these processors. Overclocking provides more performance but autonomy will decrease well awaited. These are the notebooks that have these 4000 Ryzen processors while the Ryzen 3000 mainly equip office computers. With overclocking, if you will have a higher performance, the battery fits less quickly. It is logical.
It should be noted that this software is provided by a third party and not by AMD, the manufacturer of the Ryzen processors, or by the manufacturer of the laptop. The use of this software is therefore more or less reserved for advanced users. Indeed, it is necessary to take into account the factors of use of the processor when you boost the processor: temperature parameters and the limits set by the OEM. Thus, the cooling settings should not be overlooked so as not to damage the processor and the laptop.
Overclocking or Underclocking, the RMT does everything
It is quite possible to Underclocker the CPU with this tool to have better battery life. We can therefore fix the maximum power or temperature. For example, by reducing the work power to 20 Watts, the processor operating temperature is around 60 ° C, while in normal use with a nominal power of 40 Watts, the processor generally operates at 90 ° C. Underclocking also reduces the noise emitted by the computer. Indeed, drop in operating temperature means, less cooling system (fans, etc.) that runs.

The RMT 1.0.0 software is quite complete. It includes a reporting system, allowing you to know and monitor power consumption, clock speed, temperatures, memory speeds, Infinity Fabric as well as GFX and SoC. This software allows you to modify the TDP PL0, PL1 and PL2. It also allows you to customize the duration of power supply boosts (on power supply ) of PL1 and PL2. Thus the PL1/PL2 power defined by default at 37.5W / 48 W can be reduced to 15W / 25 W. In this context, the operating temperature has dropped considerably by 30°C: From 90°C to 60°C . We can also play on the TCTL temperature and the operating power of the TDC and EDC.
From experience, Ryzen-H types are more sensitive to overclocking compared to Ryzen-Us. For underclocking, the 2 types H and U responded favorably to the different settings.
