But when I run lshw -C memory it show all 9GB:

How can I go about using all 9GB?

  • You have two different models of RAM. Try putting the same models in the same matched pair slots. This means put the KP223C-ELD into DIMM0, DIMM1 and DIMM2; and the KTW149-ELD into the other DIMM positions. – Clive van Hilten Nov 4 '12 at 10:34

I got all 9GB to show up. Here is what I did:

  1. Place 2GB modules into banks 0, 1, 2
  2. Place 1GB modules in banks 3, 4, 5
