What is OCCT?

Had a bluescreen ? Find out if it was due to hardware failure using the best all-in-one stability check & stress test available !

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.

6 Tests 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 !

Monitoring OCCT will monitor your computer's reading and present you real-time graphs showing you temperatures, voltages, fan speed, frequencies, component usage, and power consumption during your tests. We are using the AWESOME engine from HwInfo !

Built-in protection for your computer Worried about frying your components ? Turn the maximum temperature threshold in OCCT's options ! Should a component reach this critical temperature during a test, OCCT will stop itself immediately.

Test report At the end of a test, you will be able to save a full graphical report of what happened during the test, for diagnostic purposes.
