Installing DIMMs (DIMM1, DIMM2)
The following is a procedure for installing DIMM modules into a DIMM socket. 
Step 1:
Line up the DIMM module as illustrated in Figure 1, pin 1 is indicated by a small triangle on the motherboard. Insert the module straight into the socket. The DIMM module is keyed and can only be inserted one way.
Step 2:
Insure that the DIMM module is secure in the socket and snap the locking tabs located on both ends of the socket firmly into place as illustrated in Figure 1.

Once the DIMM modules are installed, the system will display the correct amount of memory, since the system automatically detects the amount installed; there are no jumper settings for memory configuration. The memory should be enabled and fully functional.
