v
When you install the second microprocessor, you must also install additional
memory and the fourth fan. See “Installing a memory module” on page 167 for
details about the installation sequence.
v
To ensure proper server operation when you install an additional
microprocessor, use microprocessors that have the same QuickPath Interconnect
(QPI) link speed, integrated memory controller frequency, core frequency, power
segment, internal cache size, and type.
v
Mixing microprocessors of different stepping levels within the same server
model is supported.
v
When mixing microprocessors with different stepping levels within the same
server model, you do not have to install the microprocessor with lowest
stepping level and features in microprocessor socket 1.
v
Both microprocessor voltage regulator modules are integrated on the system
board.
v
Read the documentation that comes with the microprocessor to determine
whether you have to update the server firmware. To download the latest level of
server firmware and other code updates for your server, go to
http://www.ibm.com/supportportal/.
v
The microprocessor speeds are automatically set for this server; therefore, you
do not have to set any microprocessor frequency-selection jumpers or switches.
v
If the thermal-grease protective cover (for example, a plastic cap or tape liner) is
removed from the heat sink, do not touch the thermal grease on the bottom of
the heat sink or set down the heat sink. For more information about applying or
working with thermal grease, see “Thermal grease” on page 273.
Note:
Removing the heat sink from the microprocessor destroys the even
distribution of the thermal grease and requires replacing the thermal grease.
v
To order an additional optional microprocessor, contact your IBM sales
representative or IBM reseller.
Installation tool has two settings for installing two different sizes of
microprocessors. The settings that are marked on the tool are “L” for smaller low
core microprocessors, and “H” for larger high core microprocessors.
To replace a microprocessor and heat sink, complete the following steps:
