5. Locate the DIMM connectors on the system board. Determine the connectors
into which you will install the DIMMs. Remember that DIMM 1 and DIMM 3
must be paired together (and must be the first installed pair) and DIMM 2 and
DIMM 4 must be paired together. The following table shows the installation
sequence.
