MSI 815 PRO User manual

CHAPTER 1 INTRODUCTION
1-1
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.
