Removing the modules one by one from motherboard
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is simplest method for isolating a failing module, but this may apply only if the motherboard have more than one module on the SIMM or DIMM Slot. By selectively removing module one at a time from the system and then running the test you will be able to find the bad module very quickly. Be sure to mark the module that passes or when it test fails.

Swap the modules around
~~~~~~~~~~~~~~~~~~~~~
When none of the modules can be removed, swap and rotate modules to find which module is defective. This technique can only be used if there are two or more modules in the system. Change the location of two modules one at a time.

For instances, place the module from SIMM slot 1 into slot 2 and place the other module from slot 2 in slot 1.
Run the diagnostic test and if either the failing data bit or address changes, you know that one of the module you have just swap is defective. By using several combinations of module swapping you should be able to check which module is defective.

Replacing with known good module
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you are unable to use either of the above two techniques, you are left to use known good modules and selectively replace of modules one by one to pin point the memory failure. This is the easiest way to detect memory failure.

Removing and cleaning the metal contacts
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If your PC system is older, sometimes dust and oxidation will cause poor contact in the SIMM/DIMM slot. Remove the module and clean the gold or tin contact with a “pencil eraser” or any cleaning solution used for video and audio head cleaning. Make sure you remember which slot is being used, and be careful not to reverse the module while reinserting into the SIMM/DIMM slot

Identifying memory failure using motherboard BIOS codes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If you are not trained to perform the correct diagnostic methods – majority BIOS developers and motherboard manufacturers have device a simple way of telling you if your system is having problem by emitting beeping tones from the build in speaker on the motherboard, without the aid of a memory tester.
