TechPowerUp Announces MemTest64 - Test Memory from Within Windows

TechPowerUp today announced MemTest64, our lightweight, standalone utility that lets you test your system memory for hardware faults and other errors. The application has a graphical user interface (GUI), and can be run from within Windows, without needing any administrator privileges. MemTest64 can also be used to test the stability of your memory performance tuning, such as overclocks and tight timings. The utility puts your memory through a battery of test patterns, while juggling data from the memory to the page file. The app is portable, and does not require any installation. This is our first public release of MemTest64, after thorough internal testing. We welcome your feedback in the app's dedicated forum on TechPowerUp Forums.
DOWNLOAD: TechPowerUp MemTest64 1.0

  • Runs on Windows XP, Vista, Windows 7, Windows 8, Windows 10. 64-bit OS only
  • Supports all modern processors, including Intel Core and AMD Ryzen
  • No reboot or DOS-mode required
  • You can control how much memory to test, to reduce operational impact

Pretty cool tool.


My findings are most memory issues are from incorrect timings and voltage being to low.

I got a little spoiled by EFI loaded USB drives containing passmark's memtest v6.
Ill give this one a go, guess. This is truly more for OCers and less for technitians.

Looks like complicated software. Do you code stuff for living then? I don't suppose TPU can generate enough money to live off?

I would only wish if such tool would exist for testing GPU memory errors. There was some long time ago one for ATI cards... but well... that's dino age.

The program recognizes only two modules out of four. Gigabyte MW50-SV0.

Hey @W1zzard, will the results output by this tool be any different from what you can get from Memtest86? Is it possible that Memtest86 will find errors that Memtest64 won't?

Memtest86 runs under DOS so that it can test virtually all of your memory. Despite the name it also is 64-bit and handles memory above 4GB just fine.

This MemTest64 program can't test memory that is in use, but you don't have to reboot to run it. As was said above it is more for testing an overclock than for diagnosing RAM issues.

Aha, so it's for stability testing. Gotcha.

If you select a sufficiently large test size, it will send everything to pagefile, freeing memory to test, except for the kernel, which is roughly 1 GB.

I guess that's true. Good point.
