Should you suspect a failing RAM stick, please follow the instruction below regarding the download and use of Memtest to test your memory for faults.
Firstly please visit the following website: http://www.memtest.org/
Once on the website please select Download (pre-built & ISOs) which can be found under the About Memtest 86+ heading.
Then, select Download – Auto-Installer for USB Key
Make a note of the download location of Memtest and run the installer.
Before plugging in your USB Key, ensure that there is no important information on the key as this will be deleted.
Once you have checked this, plug in your USB key.
Then, please select your USB Key from the drop-down menu and tick the format check box.
Then, click Create and all the necessary files will be copied onto the USB Key
Reboot the machine with that USB Key still plugged in, it should now boot into the memory testing program.
If this is not the case you may need to use the one time boot menu (usually F12 on boot) or ensure that USB is set to the first boot device in the BIOS.
If you have any issues when navigating the BIOS, please refer to your motherboards' manual or contact our technical support team,
Please allow this to run for 3 passes.
The current pass number Memtest is on can be located to the left of the Errors heading and to the right of the Test heading. The location has also been circled in black below so that it can be referred to easily.
This test will continue to loop until you press the Esc Key to stop the test and reboot.
The time it takes for the test to loop depends on the amount of memory being tested. However, i can confirm that the tests will take approximately 4-5 hours.
This will be indicated by red blocks across the bottom of the screen.
If you get any of the red blocks on the screen please look at the Failing Address listed in MB (shown in blue above)
This should help identify the RAM module that is at fault.
An example of identifying what RAM module is at fault is if you have 2x 4GB stick installed in the computer and all the errors are in the first 4096MB then it would point to it being the first stick of RAM that is faulty.
Therefore ,with this logic, If it is in the second 4096MB then it would be the second stick and so on.
To confirm that stick is faulty, remove the suspected faulty stick and re-run the test.
If you would like to discuss your results please feel free to give us a call on 02392 322 500 and choose to speak with technical support.
