Installing a second microprocessor
The following notes describe the type of microprocessor that the server supports
and other information that you must consider when you install a microprocessor:
Important: Always use the microprocessor installation tool to install a
microprocessor. Failing to use the microprocessor installation tool may damage the
microprocessor sockets on the system board. Any damage to the microprocessor
sockets may require replacing the system board.
v The server supports certain Intel Xeon scalable multi-core microprocessors,
which are designed for the LGA 1366 socket. These microprocessors are 64-bit
dual-core or quad-core microprocessors with an integrated memory controller,
quick-path interconnect, and shared last cache. See http://www.ibm.com/servers/
eserver/serverproven/compat/us/ for a list of supported microprocessors.
v The server supports up to two microprocessors. If the server comes with one
microprocessor, you can install a second microprocessor.
v Do not install an Intel Xeon
™
5500 series microprocessor and an Intel Xeon
™
5600 series microprocessor in the same server.
v Both microprocessors must have the same QuickPath Interconnect (QPI) link
speed, integrated memory controller frequency, core frequency, power segment,
cache size, and type.
v Read the documentation that comes with the microprocessor to determine
whether you must update the server firmware for the server. To download the
most current level of server firmware and many other code updates for your
server, complete the following steps:
1. Go to http://www.ibm.com/systems/support/.
2. Under Product support, click System x.
3. Under Popular links, click Software and device drivers.
4. Click System x3650 M3 to display the matrix of downloadable files for the
server.
v (Optional) Obtain an SMP-capable operating system. For a list of supported
operating systems and optional devices, see http://www.ibm.com/servers/eserver/
serverproven/compat/us/.
v To order additional microprocessor optional devices, contact your IBM marketing
representative or authorized reseller.
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 you have to replace a microprocessor, call for service.
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.
v Do not remove the first microprocessor from the system board to install the
second microprocessor.
