Any RedHat compatible distribution, has a memory test included in the
first install CD.
Just boot on it, an type memtest or mem86 or memtes86 or something
like that to start the test.
Be carrefull, some VGA adapter share the begining of the memory and
this part of the memory must be
skipped to avoid false error.
