How to Use Windows Memory Diagnostic Tool to Test RAM

Windows has an awesome tool called Windows Memory Diagnostic tool which you can use to check for possible memory problems, including testing of the Random Access Memory (RAM) on your computer. Also, whenever Windows suspects and finds any problems with your computer’s memory, It will ask you to run the Windows Memory Diagnostic tool. If you are facing any Blue screen of death (BSOD) Error, the Computer frequently hangs and often reboots during RAM intensive use (in games, 3D applications, video and graphics editors). All these problems could be symptoms of hardware problems. A defective memory stick could cause all sorts of problems to your computer. And running a Memory diagnosis would be a good thing to do as the first step of your troubleshooting process, which helps you to detect the memory problem of your PC.

The Memory Diagnostic Tools runs a comprehensive test and displays the test results so you can take immediate action.

Run Windows Memory Diagnostic Tool

Press the Windows key + R keyboard shortcut, type mdsched.exe, and click OK to launch the tool. Alternatively, search for memory and select the first result, Windows Memory Diagnostic

Now you have to choose between two options: ‘Restart now and check the problems’ or ‘Check for problems the next time I restart my computer.

• If you choose to restart and check the problems, make sure to save all your work and close all the running programs on your Windows 10 computer, or do so the next time when starting your computer.
• When you restart Windows, the Memory Diagnostics Tool automatically starts running tests on your PC’s memory.
• By default, this will start Standard mode and run all the scans available in the Basic mode, in addition to LRAND, Stride6 (cache enabled), CHCKR3, WMATS+, and WINVC tests.

You can also press the F1 key at any time to open the Windows Memory Diagnostic page to change the scan options.

You can adjust the following settings:

• Test mix. Choose what type of test you want to run: Basic, Standard, or Extended. The choices are described in the tool.
• Cache. Choose the cache setting you want for each test: Default, On, or Off.
• Pass count. Type the number of times you want to repeat the test.

Now after making changes for advanced options press F10 To Apply changes and start the Test.

It might take several minutes for the tool to finish checking your computer’s memory. Once the process is finished, your computer will reboot and return to the Windows desktop. Now When you log on, It will show you the Result. But sometimes, You may not see the result automatically. In that case, you have to find it manually. The result can be found in the Windows Event Viewer.

Find Memory Diagnostic Test Results

Sometimes, You may not see the Memory diagnostic test result automatically. In that case, You have to find it manually. The result can be found in the Windows Event Viewer.

• Press Windows + R, type eventvwr.msc and ok to open Event Viewer.
• Expand the Windows Logs Right-click System, and click on Find.
• Type MemoryDiagnostics-Results, and click the Find Next Close the Find
• On Event Viewer, double-click the MemoryDiagnostics-Results source, and see the message.

1. If the result reads “The Windows Memory Diagnostic tested the computer’s memory and detected no errors,” then you can discard memory as the root of the problem.
2. If the result shows one or more errors, you can try running an extended memory test, and recheck the results. If you continue to see at least one error, one of the RAM modules probably has problems, and it may need to be replaced.
3. Sometimes, when the test fails, the tool will be able to indicate which module has a problem with the results.

However, if it’s unable to provide that information, you may need to remove and test each memory module until you find out the one that is faulty.
