The mainboard supports Intel® Pentium
TM
4/Northwood/Prescott
processors. The mainboard uses a CPU socket called Socket 478 for easy CPU
installation. The Hetis 865G has its specific CPU cooler that is included in the
package. Follow the procedures as below to install the CPU. You can also refer
to p. 3-7 for more information.
CPU Installation Procedures
1. Turn off the power and unplug
the power cord before installing the CPU.
2. Pull the lever sideways away
from the socket. Make sure to
raise the lever up to a 90-degree
angle.
3. Look for the gold arrow. The
gold arrow should point towards the lever pivot. The CPU
can only fit in the correct
orientation.

4. If the CPU is correctly
installed, the pins should be
completely embedded into the
socket.
Any violation of the correct
installation procedures may
cause permanent damages to
your mainboard.
5. Press the CPU down firmly into
the socket and close the lever.
As the CPU is likely to move
while the lever is being
closed, always close the lever with your fingers pressing tightly on top of the CPU
to make sure the CPU is properly and completely embedded into the socket.

Overheating
Overheating will seriously damage the CPU and system, always make sure the cooling fan can work properly to protect
the CPU from overheating.
Replacing the CPU
While replacing the CPU, always turn off the ATX power supply or unplug the power supply’s power cord from grounded
outlet first to ensure the safety of CPU.

The mainboard provides two sockets for 184-pin DDR SDRAM DIMM
(Double In-Line Memory Module) and supports the memory size up to 2 GB.
You can install PC3200/DDR400, PC2700/DDR333 or PC2100/DDR266 modules
into the DDR DIMM slots.
Introduction to DDR SDRAM
DDR (Double Data Rate) SDRAM is similar to
conventional SDRAM, but doubles the rate by transferring data twice per cycle. It uses 2.5 volts as opposed to 3.3 volts used in SDR SDRAM, and requires
184-pin DIMM modules rather than 168-pin DIMM
modules used by SDR SDRAM. Three types of DDR
are available at the time of writing: PC2100, PC2700
and PC3200. High memory bandwidth makes DDR
an ideal solution for high performance PC, workstations and servers.
2.5 Memory Installation
DDR1 DDR2
Install at least one DIMM module into the slots. Memory modules can
be installed into the slots in any order. You can install either single or doublesided modules to meet your need.

1. The DDR DIMM has only one notch on the center of module. The module
will only fit in the right orientation.
2. Insert the DIMM memory module vertically into the DIMM slot. Then
push it in.
3. The plastic clip at each side of the DIMM slot will automatically close.

Installing DDR Modules
NOTE: Refer to p. 3-7 for more information.
DDR Population Rules
Install at least one DIMM module on the slots. Each DIMM slot supports
up to a maximum size of 1GB. Users can install either single- or double-sided
modules to meet their own needs. Please note that each DIMM can work
respectively for single-channel DDR, but there are some rules while using
dual-channel DDR (Please refer to the suggested DDR population table on p.
2-8).Users may install memory modules of different type and density on differentchannelDDR DIMMs. However, the same type and density memory modules
are necessary while using dual-channel DDR, or instability may happen.

ATX 20-Pin Power Connector: ATX1
This connector allows you to connect to an ATX power supply. To
connect to the ATX power supply, make sure the plug of the power supply is
inserted in the proper orientation and the pins are aligned. Then push down
the power supply firmly into the connector. The power connector supports
instant power on function which means that system will boot up immediately
when the power supply connector is inserted on the board.
