The VIA EPIA Mini-ITX Mainboard includes an embedded VIA Eden
Processor or VIA C3TM E-Series Processor. Two fan connectors (Fan 1 &
Fan 2) are provided on the mainboard, alllowing for the connection of a
CPU fan and an additional system case fan.

CPU Fan Connector
The VIA C3TM E-Series Processor
With low power consumption and advanced thermal dissipation properties,
the embedded VIA C3TM E-Series requires only a small fan to guarantee
performance and reliability. Ensure that the CPU Fan Connector is
correctly installed, as displayed below.

Overclocking
This motherboard is not designed to support overclocking.
Any attempt to operate beyond product specifications is
not recommended. We do not guarantee the damages
or risks caused by operation beyond product
specifications.
WARNING!
The VIA Eden Processor
Providing ultra-low power consumption and advanced thermal dissipation
properties, the VIA Eden Processor features a fanless design. The VIA
Eden Processor requires only a heatsink, as shown below.

The VIA EPIA Mini-ITX Mainboard provides two 168-pin DIMM slots for
PC 100/133 SDRAM memory modules. To operate properly, at least one
module must be installed.
Memory Installation
DIMM 1 & DIMM 2
SDRAM Module Installation Procedures
1.) Push the white retaining latches at either end of the DIMM slot
outwards.
2.) Align the SDRAM module with the corresponding notches on the
DIMM slot. The modules will only fit if placed in the correct position.
2.) With both hands, press the SDRAM module down into the DIMM slot
so that the white retaining latches rotate up and secure the module in
place (see picture below).

ATX 20-Pin Power Connector
To connect the ATX power supply, make sure the plugs of the power
supply are inserted in the proper orientation and the pins are correctly
aligned. Then, push down the power supply plug firmly into the connector.
The VIA EPIA Mini-ITX Mainboard requires an ATX power supply to be
connected. Before inserting the power supply connector, always make
sure that all components are installed correctly to ensure that no damage
will be caused.
