Notes

  1. Two pairs of DIMMs forms a group of four DIMMs.
  2. All four DIMMs within a group must be the same size.
  3. The minimum memory requirement is four DIMMs in Group 0.
  4. DIMMs can be installed in Group 1, Group 2, or Group 3 in any order.
  5. Each group addresses 512MB of memory. Unused memory is mapped out by the memory management hardware.
