Installation

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 1Step 1

Step 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 2Step 2

Step 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.

COM CONNECTORS

The COM connectors on the bottom of the COME8X80 provide

full IO support from the COME8X80 CPU module to the

baseboard. The pinout of the COM connectors is as shown in the

table below.
