Installing an additional 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.
Before you begin:
v
Thoroughly review the documentation that comes with the microprocessor to
determine the required BIOS update. The latest level of BIOS code for your
computer is available through the World Wide Web at
http://www.ibm.com/pc/support.
v (Optional) Obtain an SMP-capable operating system. For a list of supported
supported operating systems and other options for your computer, go to
http://www.ibm.com/pc/ on the World Wide Web; then, select your country and
navigate to the list of options for your computer.
Attention: To ensure proper computer operation when you install an additional
microprocessor, 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: A microprocessor must always be installed in socket CPU1 of the
system board.
Notes:
1. To order additional microprocessor options, see “Parts listing for the
IntelliStation Z Pro” on page 109.
2. Terminator cards are not required for empty microprocessor sockets. However,
for airflow, an empty microprocessor socket must contain a microprocessor
baffle.
3. The microprocessor speeds are automatically set for this computer; therefore,
you do not need to set any microprocessor frequency-selection jumpers or
switches.
4. If you need to replace a microprocessor, “Microprocessor and heat sink” on
page 78.
5. For additional illustrations of the system-board components, see “System-board
option connectors” on page 36.
Configuring the operating system
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 need to be manually configured to support
an additional microprocessor.
Installing an additional microprocessor on Windows NT:
If Windows NT is preinstalled on the computer, follow these steps:
1. Backup the hard disk.
2. Run the Multiprocessor Upgrade Option program, addcpu.exe before you install
the second microprocessor. The Multiprocessor Upgrade Option program is at
http://www.ibm.com/pc/support on the World Wide Web. From the IBM support
