The815PRO(MS-6326)ATX S2 mainboardisahigh-performance
computer mainboard based on Intel®815 chipset. The 815 PRO is optimized
to support the Intel®Pentium®III (FC-PGA) processor for high-end busi-
ness/personal desktop markets.
The Intel®815 chipset integrates a Display Cache SDRAM control-
ler that supports a 32-bit 133MHz SDRAM array for enhanced integrated 3D
graphics performance. It is a highly-flexible chipset which is designed to
extend the basic graphics/multimedia PC platform up to the mainstream
performance desktop platform.
The Intel®815 chipset implements the host address, control, and
data bus interfaces within a single device. It takes advantage of the
pipelined addressing capability of the processor to improve the overall
system performance. In addition, the chipset also integrates a system
memory controller that supports a 64-bit 100/133 MHz SDRAM array.
The Intel®82801AA (ICH) chipset is a highly integrated
multifunctional I/O Controller Hub that provides the interface to the PCI Bus
and integrates many of the functions needed in today’s PC platforms. It
communicates with the host controller over a dedicated hub interface and
provides added flexibility in designing cost-effective system solutions.

HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The mainboard operateswith Intel®CeleronTM/Pentium®III (FC-PGA)
processor. The mainboard uses a CPU socket called Socket 370 for easy
CPU installation. The CPU should always have a Heat 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.

The mainboard CPU Bus Frequency can be set through BIOS setup.
If CPUClock = 100MHz
Core/Bus ratio = 7
then CPU core speed = Host Clockx Core/Bus ratio
= 700MHz

Note: If you used this jumper for overclocking, you also need to
modify the CPU Bus ratio through BIOS.

2.1-4 Fan Power Connectors: CPUFAN, SYSFAN &
PSFAN
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 con-
nected to the +12V, the black wire is Ground and should be connected to
GND. If your mainboard has System Hardware 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 Hardware 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.

A. HowtoinstallaDIMMModule
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.
