OCCT is a Windows tool for evaluating the performance of your PC. It applies artificial loads to various critical hardware components, ensuring that they operate smoothly under stress. Additionally, there is an option to verify the reliability of the main power supply.

Benchmark configuration

Users can tweak the overall test duration according to personal preferences. It is possible to select the desired data set size and load type for the processor as well. Moreover, tools to change the GPU intensity range are provided.

The application lets you test RAM modules by running complex instruction sets like SSE and AVX2. This is especially advantageous for troubleshooting common memory issues. Similar to PCMark10, evaluation results can be saved as a text document and shared with IT professionals via email.

System monitoring

There are instruments for tracking critical PC metrics in real time. Users are able to view:

CPU and GPU temperature;
Clock speeds;
Voltages;
Memory capacity and more.

You can access detailed technical specifications of each internal hardware component. This includes models, serial numbers, firmware versions and other important information.
