5. By default, the Windows Memory Diagnostics Tool will run a standard test mix, use the default cache setting of each test, and use a pass count of 2 for the total number of times the entire test mix will repeat.

If you would like to change any of these default test settings, press the F1 key, use the Tab key to select which setting (Test mix, Cache, or Pass count) you want to change, change the setting to what you want, and press F10 when finished with your changes to apply them. (see screenshots below)
Note   Note
When you press F10 to apply your changes, Windows Memory Diagnostics will start over running the test based on your settings.
