OCCT is the most popular all-in-one stability check & stress test tool available.OCCT is great at generating heavy loads on your components ( CPU, GPU, Memory, GPU Memory & Power supply ) , and aims at detecting hardware errors or stability issues faster than anything else.A monitoring engine is also embedded, to ease diagnostic and see how your computer reacts under heavy load using graphs.

OCCT is free for personal use only !

If you are running OCCT in a corporate or commercial environment, you have to buy a PRO license to use OCCT

I see an increasing number of companies downloading the free version of OCCT and shamelessly using it in their corporate environment.The free version of OCCT is meant to make OCCT as useful and widely used as possible. This has been the case since it started, back in 2003.

This time, when you do this, you aren't stealing from a big company !

OCCT isn't enough to make a living as of now (far from it). Please support me and participate in keeping the free edition... free for everyone !

OCCT includes 6 different tests : OCCT and Linpack for your CPU, Memory for testing system RAM, 3D and VRAM for your Graphic card, and Power to stress your power supply. You can even monitor your PC while using an external app to generate reports using the Monitoring-only test !
