Installation
This chapter provides you with information about hardware
installation procedures. It is recommended to use a grounded wrist
strap before handling computer components. Electrostatic discharge
(ESD) can damage some components.

CPU
The VIA C3 E-Series Processor
The VIA EPIA-PE Mini-ITX mainboard includes an embedded VIA C3 or Eden
Processor. The VIA C3 Processor provides ultra-low power consumption and
advanced thermal dissipation properties. The VIA C3 Processor requires
heatsink and a CPU fan to provide sufficient cooling. Ensure that the CPU
fan is correctly installed as shown.
WARNING: This mainboard is not designed to support overclocking.
Any attempt to operate beyond product specifications is not
recommended. We do not guarantee against damages or risks
caused by inadequate operation or beyond product specifications.

Fans: CPUFAN, SYSFAN and PWRFAN
The CPUFAN (CPU fan), SYSFAN (system fan) and PWRFAN (power fan) run
on +12V and maintain system cooling. When connecting the wire to the
connectors, always be aware that the red wire is the Positive and should be
connected to the +12V. The black wire is Ground and should always be
connected to GND. The CPU system and power fan connectors have sensors
to support fan monitoring.

•Unlock a DIMM socket by pressing the retaining clips outward.
•Align a DIMM on the socket such that the notch on the DIMM
matches the break on the socket.
•Firmly insert the DIMM into the socket until the retaining clips snap
back in place and the DIMM is properly seated.
