How to test the RAM memory:

Memory tests do not catch all errors such as mismatched memory (possible even for sticks

that appear to be identical) and when faster memory is placed in system behind slower memory. So it is best to also swap sticks in and out to check for those even if all memory tests fail to show a problem.

To test RAM check here - let it run 4+ hours or so.  <-- best methodwww.memtest.org
