2. The DIMM sockets are keyed with notches and the DIMMs are keyed with cut-
outs so that they can only be installed correctly. Check that the cut-outs on the
DIMM module edge connector matches the notches in the DIMM socket.
3. Push the latches on each side of the DIMM socket down.
4. Install the DIMM module into the socket and press it carefully but firmly down so
that it seats correctly. The latches at either side of the socket will be levered
upwards and latch on the edges of the DIMM when it is installed correctly.

Check all the Jumper Settings
Check all the mainboard jumpers to ensure that the board is configured correctly.
A Note on Jumpers
A jumper consists of two or more pins mounted on the mainboard. Some
jumpers might be arranged in a series with each pair of pins numbered
differently. Jumpers are used to change the electronic circuits on the
mainboard. When a jumper cap is placed on two jumper pins, the pins are
SHORT. If the jumper cap is removed (or placed on just a single pin) the pins
are OPEN.
JP1: Clear CMOS Memory Jumper
This jumper lets you erase the system setup settings that are stored in CMOS memory.
You might need to erase this data if incorrect settings are preventing your system from
operating. To clear the CMOS memory, turn off the system, disconnect the power
cable from the mainboard, and short the appropriate pins for a few seconds.
