OCCT (OverClock Checking Tool) is a highly valued tool among oveclockers to test basic computer components that have been "overclocked" in order to achieve the highest possible performance. It also provides detailed information about your processor. The program puts a heavy load on the computer during its operation, enabling it to monitor the basic features of its basic components - i.e.

the level of CPU and RAM usage, voltage and temperature of individual cores and GPUs (provided that the hardware is equipped with appropriate sensors). There are 4 types of tests at the user's disposal: author's tests and those using the Intel LINPACK library to test the processor, as well as benchmarks checking the graphics card for 3D objects rendering and a power supply.

With the latter, both the processor and the GPU are subjected to load. All of the available benchmarks can be configured to a greater or lesser extent. After completion of the tests, OCCT generates a set of several charts, which are stored as PNG files on the disk.

They show the CPU and graphics card usage time, CPU and GPU core temperature, and voltage.
