Free edition

6 thorough hardware 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 !


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.

Personal edition

No 1-hour test limitation

Buying a Personal license removes the one-hour test limit !


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.

Pro edition

Allowed to run on domain-joined computers

OCCT's free edition won't run on computers joined to domain, this version removes that limit entirely

CSV Readings export

OCCT will generate a CSV file containing all the monitoring readings upon saving a test report. Use it to build your own graphs !

Enterprise edition

Build your own test suite

Chain different test phases to build your own schedule. Everything is done graphically in the app, using drag&drop, for an easy configuration ! You can also export test configurations to a file

Command-line support

Gain access to OCCT Command-line, a special build of OCCT Enterprise that works from a classic CMD box. Automate testing, generate test reports, run different profiles... all that made easy !

Detailed test report

Gain access to fully detailed, fine-grain test reports in HTML file format (single-file), allowing you to analyze easily the behaviour of your computer during the test, and use it as a comparison point between two different test runs.

Json and CSV test reports

With the HTML report, OCCT will generate a test summary in JSON for easily parsing the outcome of a test, and a CSV file containing all monitoring data recorded during the test, just as the Pro version

Stability testing since 2003
