You may have bad sticks, or they may be unseated. First thing to try is an SMC re-set first:

Then try a PRAM reset:

If neither works, you may have to open it up and take a look, re-seating the RAM modules.

You could also ask the Mods to move this thread into the MacBOOK Pro laptop forum as this is for discussion of the desktop Mac Pro.

That said, you are still fairly likely to get some good help from folks here anyway.
