CPU

The VIA COME8X80 board is designed with the VIA Nano

1.6 GHz NanoBGA2 processor. Other processor options (e.g., VIA
Nano 800 MHz NanoBGA2 processor) are also available as
manufacturing options. The VIA Nano 1.6 GHz processors
requires a heatsink with fan to provide sufficient cooling.

CPU Fan Connector: CPUFAN

CPUFAN run on +12V and maintains system cooling. When
connecting the cable to the connector, always be aware that the
red wire (positive wire) should be connected to the +12V pin. The
black wire is the ground wire and should always be connected to
GND.

MEMORY MODULE INSTALLATION

Memory Socket: SODIMM1

The VIA COME8X80 has one 200-pin SODIMM socket for DDR2
533/667 SODIMM SDRAM, non-ECC, memory module and
supports memory the sizes up to 2 GB.

Available DDR2 SDRAM Configuration

Refer to the table below for available DDR2 SDRAM configurations
on the mainboard.

Slot Module Size Total

SODIMM 64 MB, 128 MB, 256 MB, 512 MB, 1 GB, 2 GB 2 GB

Maximum supported system memory 2 GB

Installing the memory

Step 1

Step 1

Step 1Step 1
Insert the memory module into the SODIMM socket at a 45 degrees
angle. And make sure the notch is on the proper side.

Step 2

Step 2

Step 2Step 2
Then push down until the memory module snaps into place. The
SODIMM socket has two locking mechanisms that will click once the
memory module has been fully inserted.
