If your system is crashing or is reporting memory issues or errors in the logs, you should perform a memory test before filing any public bug reports or support requests.

This page explains how to perform a memory test on an Ubuntu Live CD and on installed Ubuntu systems.

  1. Turn On or Restart the system from a clean power on cycle,.
  2. Hold down the Shift to halt the default GRUB timeout and bring up the GRUB menu.

  3. Use the arrow keys to move to and select the entry labeled Ubuntu, memtest86+, if one exists.

  4. The test will run automatically, and continue until you end it by pressing the Escape key

  5. Allow the test to run for at least one full pass and view the report results.

If your Live CD does not include the memtest86+ entry in the GRUB menu, you can install the package on your running or installed Ubuntu system by using sudo apt install -y memtest86+, and it should add an entry for you in the GRUB menu. From there, you can reboot and follow the steps above.
