The VIA EPIA-V Mini-ITX Mainboard includes an embedded VIA Eden Proc-
essor or VIA C3™ E-Series Processor. Two fan connectors (Fan 1 & Fan 2)
are provided on the mainboard, allowing for the connection of a CPU fan and
an additional system case fan.

CPU Fan Cable CPU Fan / Heatsink
CPU Fan Connector
The VIA C3™ E-Series Processor
With low power consumption and advanced thermal dissipation properties,
the embedded VIA C3™ 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 guar-
antee the damages or risks caused by operation be-
yondproductspecifications.
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-V 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-V 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.
