If the hardware cannot read the memory sticks as 1 GB modules, how can
the OS hope to see it?  Sounds like B.S. to me.  Once the replacement
modules come in, make sure they work, then request that they refund you
the difference for that "slightly higher price" junk.  If they refuse,
never deal with that company again, and pass on your experiences to us
so that others can avoid them.
