Installing DIMMs
CAUTION
Install memory in the DIMM sockets prior to installing the PCI Express* x8
card to avoid interference with the memory retention mechanism.
To make sure you have the correct DIMM, place the DIMM on the illustration in Figure 6 showing
the DDR2 DIMM. All the notches should match with the DDR2 DIMM.
