The name OCCT comes from OverClock Checking Tool. This application will let you benchmark and overclock your system components.

Features:

  • Up to 16-core support ( for instance, up to a Quad-Kentsfield or an Octo-Conroe )
  • Customizable tests ( Duration, Priority, CPU or RAM, ... )
  • CPU and Motherboard detection
  • Monitoring support through 3rd party application ( i.e. MBM5, Speedfan and Everest Ultimate Edition 3.50 or above )
  • Can produce graphs showing temperature and voltages during the test : Unique feature !
  • Multi-language support

What's New:

  • Main: Small update to avoid a false positive detection in Microsoft's antivirus
  • Main: Added an auto-updater feature
  • Main: Lots of code cleanup and refactoring
  • Main: Workaround - Nvidia drivers apply G-sync to OCCT's GUI (which is pointless), which results in mouse stuttering
  • UI: Revamped the settings screen and moved it into its separate section
  • Monitoring: Added Core usage monitoring section
  • Monitoring: Added a no monitoring option - the engine will still be started, but never updated to keep CPU usage low
  • Monitoring: Added a "Monitoring interval" settings, controlling how often should the monitoring be updated
  • Monitoring: Added a "Graph update" setting, controlling how often should the graphs be updated
  • Monitoring: Improved CPU Core usage sensor detection algorithm
  • CPU: Fixed issues with core affinity on systems with more than 64 cores
  • CPU: Added "Cycle" display in summary, which shows which cycle you are in. Each cycle uses different operands
  • CPU: Added "Start at cycle" option, which enables you to skip to a particular cycle if it proved more effective than others
  • Memory: Fixed various issues on systems with more than 64 cores
  • GPU: You can now test simultaneously several GPUs, even of different brands (no SLI/Crossfire required)
  • Power: You can now test simultaneously several GPUs, even of different brands (no SLI/Crossfire required)
  • Enterprise: Added a new program "OcctCmd", to the enterprise edition - you can now run OCCT without any GUI, using a full command line interface (supports running tests only, there's no way to replicate OCCT's GUI in command line)
  • Enterprise: Greatly improved the report generation speed at the end of a long test
