Top 5 Free Memory Testing Software Tools
A List of the Best Free Computer Memory Test Tools
Memory testing tools are software programs that perform detailed tests of your computer's memory system.
The memory installed in your computer is very sensitive. It's always a good idea to test newly purchased memory for errors and a memory test is always in order if you suspect that you may have a hardware problem.
Memtest86 is a completely free, stand-alone, and extremely easy to use memory testing program. If you only have time to try one memory testing tool on this page, try Memtest86.
While this program is free, BradyTech Inc. can ship you a CD-ROM with Memtest86 preinstalled plus detailed documentation, all for around $10USD.
Unless you're a hardware developer or other expert, the free download and free basic support available on the site should be enough.
I highly recommend Memtest86!
Windows Memory Diagnostic is a free memory test tool provided by Microsoft. Very similar to other memory testing programs, Windows Memory Diagnostic performs a series of extensive tests to determine what, if anything, is wrong with your computer memory.
Important: You do not need to have Windows (or any operating system) installed to use Windows Memory Diagnostic.
Simply download the installer program and then follow the instructions to create a bootable floppy disk or ISO image for burning to a CD.
After booting to the CD or floppy disk, Windows Memory Diagnostic will automatically begin testing the memory and will repeat the tests until you stop them. If the first set of tests finds no errors, chances are your memory is good.
3. M2K MemScope
M2K MemScope is a free memory testing software program from the makers of Micro-Scope - a large suite of professional, time tested (and expensive) computer diagnostic tools.
MemScope performs a wide variety of tests in an attempt to locate even the smallest issue with your memory. Many advanced testing options are available but the "Run All" test is equivalent to tests in other programs and is a safe bet if you're not a memory expert.
MemScope is freely downloadable from M2K's site, linked below. You will have to fill out a short form but you're quickly brought to the download link. I couldn't get the provided ISO file to work but I did use the "MemScope installer" option to create a bootable floppy disk without problem.
Memtest86+ is a modified and presumably more up-to-date version of the original Memtest86 memory testing program, profiled in the #1 position above. Memtest86+ is also completely free.
I would recommend performing a memory test with Memtest86+ if you have any problems running the Memtest86 memory test or if Memtest86 reports errors with your memory and you would like a really good second opinion.
It might seem a bit strange that I rank Memtest86+ as the #4 pick, but since it's so incredibly similar to Memtest86, your best bet is to try Memtest86 followed by my #2 and #3 picks, both of which operate differently, providing you with a more well-rounded set of tests.
DocMemory Memory Diagnostic is yet another computer memory test program and works very similarly to the other programs I have listed above.
One major disadvantage of using DocMemory is that it requires that you create a bootable floppy disk. Most computers today don't even have floppy drives. The better memory test programs (above) use bootable CDs instead.
I would recommend using DocMemory Memory Diagnostic only if the programs I have listed above do not work for you or if you'd like yet one more confirmation that your memory has failed.
On the other hand, if your computer isn't able to boot a CD, which is what most of the above programs require, DocMemory Memory Diagnostic may be exactly what you've been looking for.
