Best Free Memory Testing Utility


Many unusual and seemingly unrelated computer problems can occur if a computer memory module is malfunctioning. Memory testing utilities will help you discover if there are problems with your RAM.

If an error is found, you may have to remove all but one of your modules and test them one at a time to discover which one is actually causing the problem.

In a Hurry?

Memtest86+ is a stand-alone GPL utility that provides comprehensive memory testing for all x86 based PCs regardless of the operating system.

It can be run from a floppy disk, CD, or USB drive. It's a tool geared towards experienced users, so if that's you, download it now for your PC toolkit. It can be downloaded as an ISO file for creating a boot disk or as an executable file.


Another good testing utility is MemScope which runs from a self booting floppy disk.

It uses eight different testing patterns that can be run once or continuously. It has a good reporting feature, and can be set to reboot after the completion of its tests.

MemScope must be run from a floppy, which is created by the downloaded file, so have a floppy handy. Registration is required so expect some email advertising, and be aware there are also some harmless advertisements in the product itself.

Another good free program is Microsoft's Windows Memory Diagnostic. Unfortunately, it has problems dealing with 4 GB or more of RAM.
