Want to benchmark or do stress test on your Linux PC or laptop? The all-in-one solution OCCT can now do the job for you!

OCCT, stands for Overclock Checking Tool, is a popular computer hardware stability testing, benchmark, and monitoring tool. It offers pro, enterprise, and command line versions that need to pay for use, as well as a personal use edition with all core functions for free.

OCCT was a Windows only software. Since few weeks ago, it added native Linux support! And, it’s been made pre-installed in CachyOS Linux Distribution.

With OCCT, you may do stability test on your CPU, Memory, GPU, Video RAM, Power supply, and combination which is useful to identify hardware instability issues, such as overheating.

It can also benchmark CPU, Memory, and upload to its online database, where you can compare your CPU / Memory performance with others by viewing the rankings and scores.

As you see in the screenshot above, it also monitor CPU, GPU, Memory usage, temperature, and frequency in header bar. While, there’s detailed monitoring support with table view and graph view of the following information:

• per core CPU usage, temperature, and frequency.
• GPU usage, temperature, VRAM usage, power limit.
• physical memory load in MB and percentage.
• fan speed.
• battery voltage.
• storage disk (HDD/SSD) temperature.

OCCT also has downside. That’s every time when I clicking “Start”, it pops up a dialog that needs to wait 10 seconds counting down, though it may be for the personal version only.

How to Install OCCT in Ubuntu & other Linux

• Then, launch text editor and create an empty document, and paste the following lines into file:

  [Desktop Entry]
  Name=OCCT
  Comment=all-in-one stability, stress test, benchmark and monitoring tool
  Exec=OCCT
  Icon=occt
  Terminal=false
  Type=Application
  Categories=Utility;
