Occasionally I use MemTest86 to perform a memory diagnostic, however, it is a bootable application, then I'm in search of a similar application that can run under the OS environment.

I'm aware of MemTest (is not the previouslly mentioned MemTest86), however, it seems very simple, I would like to discover something more complete.


  • For Windows.
  • Free or paid, no matter.
  • In continued development.
  • Has a GUI.
  • DDR2/DDR3/DDR4 support.
  • Can perform x64 tests (see image below).


These are all the noticeable features that MemTest86 shows in their website, I just would like a program complete of good features like these:

    The problem is that memtest needs complete control of all of the RAM and Windows itself takes control of the same, not to mention using a chunk, plus of course for all of the timing tests would be thrown out by windows. And if your memory area under test got swapped to disk - shudder. Feb 19, 2016 at 7:12

    As @SteveBarnes said, this most likely isn't possible. Even if it were possible, the results would be incomplete/inaccurate. The only (good) way to test your RAM is to boot a computer into a RAM testing utility where said utility has full control over the RAM and can run freely, uninterrupted by an OS.

  • Thankyou guys for the explanations. If I delete my question without no answers, it will affect to my ban-rate?, well, no matter, I will no risk, maybe is better to let this open so people can learn from the comments above. Feb 20, 2016 at 11:53
