Publisher's Description

An extensive tool for tesing PC stability, RAM and CPU:

OCCT is a stability checking tool that was created back in 2003, and was regularly updated since. It enables you to fully test your computer's stability, using 4 different tests : CPU:OCCT and CPU:Linpack aimed at testing the CPU, GPU:3D for the GPU stability, and Power Supply, a combination of CPU:Linpack and GPU:3D to fully load your Power Supply.

Each test can be run indefinitly, or for a fixed amount of time. You can even include an idle period at the beginning or at the end of a test, to better see how your computer's temperature rise from an IDLE state to fully loaded, and the other way round.

OCCT also embeds a monitoring engine, giving you complete readings of the computers inner temperatures, voltages, and fan speed, and displays them both in graphs plotted in real-time and at the ne of a test.

OCCT features and highlights:
  • Up to 16-core support
  • Customizable tests (Duration, Priority, CPU or RAM)
  • CPU and Motherboard detection
  • Monitoring support through 3rd party application
  • Can produce graphs showing temperature and voltages during the test
  • Multi-language support
  • OCCT's main UI has been completly revamped
  • Graphs now shows a 2nd line showing the CPU usage / FPS during the test
  • CPU usage is now instantaneous instead of an average since the start of the test
  • OCCT now has 5 different tests. The descriptions are at the end of the changelog
