Uncertain RAM can cause a large number of problems. Broken data, crashes and unknown behaviour. Bad RAM is one of the most irritating computer issues to have as symptoms are often random and really hard to resolve. The program can help identify bad RAM (or rule it out as a cause of system fluctuation). As such it is commonly used by system builders, computer repair shops, overclockers and computer manufacturers.


  • Great tool for testing for RAM errors.
  • Free.


  • It can also be slow to run.
