HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The mainboard operates with Intel® CeleronTM/Coppermine processor. The
mainboard uses a CPU socket called Socket 370 for easy CPU installation.
The CPU should always have a eat Sink and a cooling fan attached to
prevent overheating.
3. Press the lever down to
complete the installation.
2. Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CPU. Match
Pin 1 with the white dot/cut
edge. Then, insert the CPU.
It should insert easily.

from the socket. Then, raise
the lever up to a 90-degree
angle.

The BIOS can be used to set the CPU ost Bus Frequency Clock.
If CPU Clock = 66M z
Core/Bus ratio = 3.5
then CPU core speed = ost Clock x Core/Bus ratio
= 66M z x 3.5
= 233M z

2.1-3 Fan Power Connectors: CPUFAN SYSFAN
These connectors support system cooling fan with + 12V. It supports three
pin head connector. When connecting the wire to the connector, always
take note that the red wire is the positive and should be connected to the
+12V, the black wire is Ground and should be connected to GND. If your
mainboard has System ardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of this function.
For fans with fan speed sensor, every rotation of the fan will send out 2
pulses. System ardware Monitor will count and report the fan rotation
speed.
Note: 1. Always consult vendor for proper CPU cooling fan.
2. CPU FAN supports the FAN control. You can install PC Alert
utility. This will automatically control the CPU FAN Speed according
to the actual CPU temperature.

Note: You can clear CMOS by shorting 2-3 pin, while the system is off.
Then, return to 1-2 pin position. Avoid clearing the CMOS while
the system is on, it will damage the mainboard. Always unplug
the power cord from the wall socket.

A. ow to install a DIMM Module
1. The DIMM slot has 2 Notch Keys VOLT and DRAM, so the
DIMM memory module can only fit in one direction.
2. Insert the DIMM memory module vertically into the DIMM slot.
Then push it in.
3. The plastic clip at the side of the DIMM slot will automatically
close.

2. To operate properly, at least one 168-pin DIMM module must be
installed.
3. This mainboard supports Table Free memory, so memory can be installed
on DIMM1 or DIMM 2 in any order.
4. Supports 3.3 volt DIMM.
5. The DRAM addressing and the size supported by the mainboard is
