To optimize or configure the processor (CPU) of the PC, the graphics card or even the RAM memory to improve the overall performance of the computer, there are several ways. Thanks to some programs it is no longer necessary, as it once was, to touch the BIOS options and you can change the speed of the processors via software, with tools that are more or less simple to use or in any case more intuitive and safe. .
This article will not be so much a guide of how to do it but a list of the best free programs released by the same manufacturers of CPU and vide cards, to use depending on the type of computer you have.

In general they can also be used by making experiments even if it is always necessary to keep in mind that increasing the speed (or Clock) of the processors leads, in addition to an increase in speed, also a greater consumption of energy and of the heat released. Furthermore, you need to change the power of the CPU and the video card, without exaggerating, step by step, trying to use the automatic options as much as possible and checking, every time you increase the speed, that the computer remains stable and does not give errors. Obviously their use is not absolutely obligatory, these are programs that can entertain the most geeks and those who want a computer as best as possible with the components it has.

1) AMD Wattman
If your computer uses an AMD CPU, you can adjust its performance settings, speed and even CPU and RAM memory management directly from the Radeon control software. AMD Wattman (for older video cards it is found under the name AMD OverDrive) is a free program that is also quite simple to use thanks to semi-automatic procedures for testing changes. The software allows you to control the speed of the fans and provides diagnostic tools to fix any problems with the PC components. With this utility you can manage the functions of the graphics card, enable graphics acceleration, change the power of the GPU and configure the displays.
Wattman can be found on the Games tab of the AMD Control Center settings. is the program to manage the performance of the graphics card. Wattman's settings are the default GPU settings, so if you load a stable overclocking configuration into Wattman, it will load on the next boot. With Wattman you can manage memory timing to add some extra FPS to games.
You can read a detailed guide on how to use it to overclock your AMD graphics card in another article.

2) Sapphire Trixx, for overclocking AMD Sapphire video cards. In addition to Overdrive or Wattman, it is possible to download and install Trixx to get the most out of the video card and perform a more decisive, more delicate, but which can give more satisfaction overclocking. Its main drawback is limited support for overvoltage and as heavy overclocking is dependent on increasing core voltage, even if voltage regulation does not void the warranty in most cases, overloaded chips can generate a lot of heat while consuming energy with the risk of damaging the components. Trixx is therefore for experts, for those who have an adequate cooling system for their video card.

3) Intel XTU (Extreme Tuning Utility)
This is the program for Intel processors in order to configure the performance of the CPUs and seek a balance in the parameters to increase their speed.
Using XTU, it is also possible to activate a technology called Turbo Boost for maximum performance without risking problems.
For older Intel video cards, you can download Intel Desktop Control Center no longer updated since 2011.

4) NVIDIA Control Panel
This is the control panel for NVIDIA video cards so you can change all graphics card settings from one place.
In addition to several basic options, it also offers some other utilities to manage CPU, motherboard, memory and power supply.
For older Nvidia video cards you can also download nTune even though it hasn't been updated since 2007.

5) MSI Afterburner is a very popular app because it works with everything, both NVIDIA GeForce and ATI Radeon graphics cards.
With Afterburner, you can overclock the processor, adjust the fan speed, adjust the voltage and control the clock speed, temperature and other settings, all from the desktop.

6) EVGA Precision X 1 is a program similar to MSI Afterburner, specialized for NVidia GeForce processors. The Precision X program allows you to adjust the voltage, the speed of the fans and create customized and automatic profiles to be activated in different conditions. The Precision X1 "OC scanner" has a key feature: the ability to automate the overclocking process by testing a range of clock speeds and voltages to identify stable overclocking for your computer.

7) AMD Ryzen Master, for overclocking the Ryzen processor. If you are lucky enough to have an AMD overclockable processor, you can easily achieve a massive speed boost with this program. Unlike Intel, AMD does not block the clock multiplier on Ryzen CPUs so you can freely set the clock speed without affecting anything else.

8) is a site that offers several small tools for monitoring the performance of CPUs and video cards.
The most popular program are CPU-Z (cited in the post on Test RAM, temperature, Cpu overclock, video cards and peripheral stability check), TMonitor and HWMonitor (cited among the programs to check the heat and temperature of the PC)

In another article there are also other programs to do theCPU processor and video card overclocking to increase PC performance
These above are just a few programs to use to change CPU and GPU processor speeds, but they are the easiest to use and also the most proven.
