    The existing factory stick is Hynix PC2700, DDR 333 512MB SO-DIMM.

    When I try to add a TwinMos PC2700, DDR 333 512MB SO-DIMM (that is pulled from an Averatec in the office that just got a 1GB stick), the unit does two loud beeps and does not boot up. If I flip them around in the slots, same thing.

    Yet, I can boot up with either stick in alone. Any ideas why they won't play together?
