CPU
The VIA Eden-N Processors
The VIA VT310-DP Mini-ITX
mainboard includes two embedded
VIA Eden-N Processors. The dual
Eden-N Processors provides ultra-low
power consumption and advanced
thermal dissipation properties. The
dual Eden-N Processors requires only
a heatsink to provide sufficient cooling,
as a fanless solution, by satisfying the VIA recommended system-level
thermal guideline. For systems designed to include a CPU fan, please
ensure that the CPU fan is correctly installed as shown.
Installation
11
CPU Fan and System Fan: CPUFAN1, SYSFAN and FAN3
The CPUFAN1 (CPU fan), SYSFAN2 (system fan) and FAN3 runs 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.
CPUFAN_PWM is a switch that is used by high-quality fans to monitor the
system temperature and will automatically adjust according to the
environment.

MEMORY MODULE INSTALLATION
The VIA VT310-DP Mini-ITX mainboard provides two 184-pin DIMM slots for
DDR400/333/266 SDRAM memory modules and supports the memory size
up to 1.5GB.
DDR SDRAM Module Installation Procedures
• Locate the DIMM sockets in the motherboard.
• 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.
Available DDR SDRAM Configurations
Refer to the table below for available DDR SDRAM configurations on the
mainboard.
Slot Module Size Total
DIMM1 64MB, 128MB, 256MB, 512MB, 1GB 64MB-1GB
DIMM2 64MB, 128MB, 256MB, 512MB, 1GB 64MB-1GB
Maximum supported system memory 64MB-1.5GB
Installation

CONNECTING THE POWER SUPPLY
The VIA VT310-DP Mini-ITX mainboard supports a conventional ATX power
supply for the power system. Before inserting the power supply connector,
always make sure that all components are installed correctly to ensure that
no damage will be caused.
ATX 20-Pin Power Connector
To connect the ATX power supply, make sure the power plug is inserted in
the proper orientation and the pins are aligned. Then push down the plug
firmly into the connector.

CONNECTORS
Hard Disk Connector: IDE1
The mainboard has a 32-bit Enhanced IDE and Ultra DMA 133/100 controller
that provides PIO mode 0~4, Bus Master, and Ultra DMA 133/100 functions.
You can connect up to two hard disk drives, CD-ROM and other devices.
IDE1

If two drives are connected to a single cable, the jumper on the second
drive must be set to slave mode. Refer to the drive documentation supplied
by the vendor for the jumper settings.
Serial ATA Connectors: SATA1 and SATA2
These next generation connectors support the thin Serial ATA cables for
primary internal storage devices. The current Serial ATA interface allows up
to 150MB/s data transfer rate, faster than the standard parallel ATA with
133 MB/s (Ultra DMA).
