The interface in OCCT: OverClock Checking Tool couldn't be more intuitive. On the left, you have three different graphics showing the use of CPU, GPU and RAM. At anytime, you can run a specific test that will put these three aspects of your computer to the test to detect any possible error. Meanwhile, on the right side of the interface, you'll find a detailed summary of your computer, the temperature, voltage, frequency, and fan speed.
