A single license allows personal use of the software on up to five computers at a time. The price of a license is 9,99 € including VAT 24 %.

Once the payment is complete, a download link and a product key will be automatically sent to your e-mail address.

Q: An error was detected, is my RAM bad?

A: If you haven't overclocked your system, yes.

Q: The test runs very slowly on Windows 7, how to fix this?

A: Change the RNG (Random Number Generator) to XORWOW on the Advanced tab. The default RNG is a function provided by the Windows API and its implementation is somehow different on Windows 7 causing poor performance.

Q: How long should I test?

A: Error detection rates by test duration*:

  • Duration ≤ 1 min: 47,44 %
  • Duration ≤ 5 min: 74,41 %
  • Duration ≤ 10 min: 83,66 %
  • Duration ≤ 30 min: 95,67 %
  • Duration ≤ 60 min: 98,43 %

* RAM Test 1.1.0.0, stop on error

Q: How much coverage is enough?

A: Error detection rates by test coverage*:

  • Coverage ≤ 100 %: 64,57 %
  • Coverage ≤ 200 %: 75,79 %
  • Coverage ≤ 400 %: 82,68 %
  • Coverage ≤ 800 %: 91,34 %
  • Coverage ≤ 1600 %: 96,06 %
  • Coverage ≤ 3200 %: 98,03 %
  • Coverage ≤ 6400 %: 99,41 %

* RAM Test 1.1.0.0, stop on error, normalized to 16384 MB test region size

Q: Can CPU cache instability distort the test results?

A: Yes, but on default settings this is very unlikely. You shouldn't start overclocking RAM until your system is otherwise completely stable.
