Hi Scott :)
   Ok.... Sorry for being late in replying... but I was sorta busy at the
moment you sent this email Scott :)

   What I learned when I contacted HP and Lund about memory upgrades for
our 979-200 was that if you have only 1 memory carrier then put the biggest
modules in the first bays... if you have 2 memory carriers then make sure
that you balance the memory... ie... make the 2 memory carriers as close to
identical twins in your setup as possible!

   If you unbalance the memory on the carriers you will see your
performance drop to a level that it will seem as if you took memory out!!!!
