Windows 7 x64 - How can I test my memory?

Memtest86+


The quickest and easiest way in 7 is to use the built-in memory diagnostic.

  1. Click Start or press the Windows key
  2. Type "mdsched.exe" (without the quotes)
  3. Chose one of the available options.

If you choose the second option, the scan will start the next time you boot the computer. If you choose the first option, the computer will reboot and start the scan immediately.

During the scan, you will see options to change the type of scan and how many times to scan. You should leave it alone unless you really suspect something wrong with your RAM and the normal scan does not find it.

Once the scan finishes, Windows will start, and within moments a bubble notification will appear, stating that the scan is finished. Click on this bubble to view the scan report.

Memtest86+ does have more options, but requires a separate download and has to be burned to a disc, and does not generate a printable report.


Right after BIOS, before windows starts, push F8. Select Memory Test from the options. Run the long test, it'll take a long time.
