DIMM Module Installation
Figure 5 displays the notch marks and what they should look like on your DIMM memory module.
DIMMs have 168-pins  and two notches that will match with the onboard DIMM socket. DIMM modules are installed by placing the chip firmly into the socket at a 90 degree angle and pressing straight down (figure 6) until it fits tightly into the DIMM socket (figure 7).
