INSTALLATIONS
Installing the CPU
The MB879 board supports a Socket 479 processor socket for Intel
Pentium
®
M or Celeron® M processors.
The processor socket comes with a screw to secure the processor. As
shown in the left picture below, loosen the screw first before inserting
the processor. Place the processor into the socket by making sure the
notch on the corner of the CPU corresponds with the notch on the inside
of the socket. Once the processor has slide into the socket, fasten the
screw. Refer to the figures below.
®
NOTE:
6
Ensure that the CPU heat sink and the CPU top surface are in
total contact to avoid CPU overheating problem that would
cause your system to hang or be unstable.
MB879 User’s Manual
INSTALLATIONS
Installing the Memory
The MB879 board supports one DDR2 memory socket for a maximum
total memory of 1GB in DDR2 memory type.
Installing and Removing Memory Modules
To install the DDR2 modules, locate the memory slot on the board and
perform the following steps:
1. Hold the DDR2 module so that the key of the DDR2 module align
with those on the memory slot.
2. Gently push the DDR2 m odule in an upright position until the clips of
the slot close to hold the DDR2 module in place when the DDR2
module touches the bottom of the slot.
3. To remove the DDR2 module, press the clips with both hands.
