It's a binary executable compiled for harmattan. You need to give the file a permission to execute and also you would have to have it in a directory that's included in your $PATH variable (for example /usr/local/sbin) if you want to execute it by simply typing it's filename.

Here's a step by step example how to download and run it. There are ofcourse countless of other ways. I assume that you have developer mode enabled and wget installed.

1. Either login via SSH or open meego-terminal on your N9. Change to root and download the memtester binary file:

Code:

$ devel-su
<rootme>
# wget http://raspi.dy.fi/ladoga/harmattan/memtester/memtester

2. Give memtester executable rights and run it from current directory:

Code:

# chmod a+x memtester
# ./memtester 1G 5

Then let it complete and it will tell you the results. If your RAM is faulty your phone can reboot or freeze during the test.
[EDIT] Above is only a very quick test and won't spot all problems. For more though one you might want to run "memtester 1G" (just leave the loop argument out) and let it run overnight.

After a succesfull run you'll see something like this:

Code:

Loop 5/5:
  Stuck Address       : ok         
  Random Value        : ok
  Compare XOR         : ok
  Compare SUB         : ok
  Compare MUL         : ok
  Compare DIV         : ok
  Compare OR          : ok
  Compare AND         : ok
  Sequential Increment: ok
  Solid Bits          : ok         
  Block Sequential    : ok         
  Checkerboard        : ok         
  Bit Spread          : ok         
  Bit Flip            : ok         
  Walking Ones        : ok         
  Walking Zeroes      : ok         
  8-bit Writes        : ok
  16-bit Writes       : ok
