Installing a microprocessor and heat sink
The following notes describe the types of microprocessor that the server supports
and other information that you must consider when you install a microprocessor:
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
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. 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 x3400 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
The heat-sink FRU is packaged with the thermal grease applied to the underside:
– 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.
– You must replace the thermal grease if it becomes contaminated or has come
in contact with another object other than its paired microprocessor.
– The thermal grease is available as a separate FRU.
v
Do not remove the first microprocessor from the system board to install the
second microprocessor.
v
Some models support dual-core processors and quad-core processors. Do not
use dual-core processors and quad-core processors in the same server. Install all
dual-core or all quad-core processors in the server.
