Are you sure about mixing memory densities. If I'm understanding you
right now have 2 sticks of 2GB and 2 sticks of 1GB for a total of 6GB.
My main PC is a MSI MoBo and it tells you that all sticks must be same
density or you will get weird things happening with lock-ups not
uncommon. My Gig-A-Byte MoBo is the same.
