Installing A CPU Upgrade

If you are installing this mainboard it will not have a CPU
installed unless your vendor installed one when you purchased
the board. If the mainboard is installed in a system, there will
already be a CPU installed. In either case the information and
procedure for installing a CPU is the same. Since the more likely
scenario is that you are installing an upgrade, this section assumes
that is what you are doing.

The Basic Procedure

To install a CPU on this mainboard you need to set up the
board for a specific CPU by doing the following:
• Set the External Clock Speed
• Set the Clock Multiplier Factor
• Set the CPU Voltage
You configure the CPU settings by adjusting jumper settings
on the board. In order to do this, you will need to know some
information about the CPU you plan to install. This should be
provided by the CPU vendor or by the vendor you buy the chip
from. You'll need the following information:
• CPU Internal Clock Speed
• CPU Voltage
The internal clock speed is the speed the CPU operates at to
process data and is the one used by CPU manufacturers to indi-
cate the speed of the chip, for example, a 233MHz Intel Pentium
The CPU also has an external clock speed which is the speed at
which it interacts with external components.
CPU voltage may either be the same internally and externally
or it may be split, depending on the CPU design. Some proces-
sors use one voltage for the 'core' (Vcore) and another for input/
output (Vio).
