I am new here and i have a friend with a problem, she has a new compaq computer with only 128mb memeory she ordered a 256 mb stick of memory, and i installed it. The computer says only 224 mb is avaliable and with a 128+256 should be reading at 384,is there a setting that could be wrong or is it a bad memory chip? I never have had this problem as it either was non- reconized or the full memory was avaliable. Any help or suggestions are welcome.
