MemTest86+ is a software tool that tests the capability of RAM. When the test is run, the RAM will accept and keep random patterns of data sent to it. It’s to be remembered that there are no errors when different parts of memory try to interact and there are no conflicts between memory addresses. You will need a bootable USB Flash drive to perform the function.
