Installing a second microprocessor
Your computer comes with one microprocessor installed on the system board. Your
computer supports up to two microprocessors. With two microprocessors, your
computer can operate as a symmetric multiprocessing (SMP) computer. With SMP,
certain operating systems and application programs can distribute the processing
load among the microprocessors.
Note: When installing microprocessor options, lay the computer on its side.
The following notes describe information that you must consider when installing an
additional microprocessor in your computer:
v Read the documentation that comes with the microprocessor to determine
whether you need to update the computer basic input/output system (BIOS)
code. The most current level of BIOS code for the computer is available from
http://www.ibm.com/support.
v (Optional) Obtain an SMP-capable operating system. For a list of supported
operating systems, go to http://www.ibm.com/pc/us/compat/.
v To ensure proper computer operation, use microprocessors that have the same
cache size and type, and the same clock speed. Microprocessor internal and
external clock frequencies must be identical. You can use the
Configuration/Setup Utility program in your computer to determine the specific
type of microprocessor on your system board.
Important: The first microprocessor must always be installed in the
Microprocessor 1 socket.
v The microprocessor speeds are automatically set for this computer; therefore,
you do not need to set any microprocessor frequency-selection jumpers or
switches.
v Terminator cards are not required for empty microprocessor sockets. However,
for airflow, an empty microprocessor socket must contain a microprocessor
baffle.
v If you need to replace a microprocessor, see “Microprocessor and heat sink” on
page 60.
v For additional illustrations of the system-board components, see “System board
option connectors” on page 71.
v To order additional microprocessor options, contact your IBM marketing
representative or authorized reseller.
v For a list of supported microprocessor options for your computer, go to
http://www.ibm.com/pc/; then, select your country and navigate to the list of
options for your computer
The Microsoft Windows XP operating system that comes preinstalled on your
computer automatically configures itself when an additional microprocessor is
installed. Other operating systems might have to be manually configured to support
an additional microprocessor. See the User’s Guide on the IBM IntelliStation
Documentation CD for instructions.
Complete the following steps to install an additional microprocessor:
1. Read the safety information beginning on page 127 and the guidelines in
“Handling static-sensitive devices” on page 23.
2. Turn off the computer and all attached devices. (See “Turning off the
computer” on page 9.)
