Verifying the health and capabilities of the system's installed physical memory can be done using a variety of dedicated applications. Among those who take the time to investigate deeper and in areas not even detectable for most utilities you can find Memscope.
This is not a standalone program but an image that you have to burn to a disc then run it at system boot. The utility has all the RAM at its disposal for testing since the operating system is not running and this means that the results will consequently be more precise than those of a tool that can only be loaded from Windows.
Cross-platform and OS independent, Memscope is ready to be put either on an optical disc or on a floppy, so you have to choose the download package that best suits your needs.
The great thing about this software is that it doesn't require complex configurations or advanced knowledge to use it. Less experienced users will only have to write the data image and use that medium as the first boot device to have the test start automatically.
All in all, Memscope can surely be a good solution for assessing the performance abilities of your RAM. Since it doesn't need more than a CD or a floppy disk, and is really easy to deploy, it might be worth a try if you want to get detailed information about your system's physical memory.
