Installing A Second Microprocessor And Heat Sink - IBM System x3690 X5 Installation And User Manual

Installing a second microprocessor and heat sink

The following notes describe the type of microprocessor that the server supports
and other information that you must consider when you install a microprocessor
and heat sink:
v Be extremely careful, the contacts are very fragile.
v The server supports up to two Intel Xeon four-core, six-core, or eight-core
microprocessors (depending on your model). To confirm that the server supports
the microprocessor, see http://www.ibm.com/systems/info/x86servers/
serverproven/compat/us/ for a list of supported microprocessors.
v Do not mix four-core, six-core, and eight-core microprocessors in the same
server.
v The microprocessor options that IBM supports are limited by the capacity and
capability of the server. Any microprocessor options that you install must have
the same specifications as the microprocessor(s) that came with the server.
v The first microprocessor must always be installed in microprocessor socket 1 on
the system board.
v When one microprocessor is installed, a heat sink filler is not required for
microprocessor socket 2, however, the microprocessor air baffle, the DIMM air
baffle, or the memory tray must be installed to provide proper system cooling.
v Do not remove the first microprocessor from the system board when you install
the second microprocessor.
v When you install the second microprocessor, you must also install additional
memory. See "Installing a memory module" on page 51 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 Do not mix Intel Xeon
Series microprocessors in the same server, it is not supported. In addition:
– Intel Xeon EX versions of the 6000 and 7000 Series microprocessors are
supported only on machine types 7148 and 7149.
– Intel Xeon EX E7 Series microprocessors are supported only on machine types
7147 and 7192.
v Both microprocessor voltage regulator modules are integrated on the system
board.
v If you have to replace a microprocessor, call for service.
v Read the documentation that comes with the microprocessor, so that you can
determine whether you have to update the server firmware. To download the
latest level of the server firmware and other code updates for your server, go to
http://www.ibm.com/supportportal/.
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 details, see the information about
thermal grease in the Problem and Determination Service Guide.
