Installing An Additional Microprocessor - IBM 8670 - Eserver xSeries 345 Installation Manual

Installing an additional microprocessor

The following notes describe the type of microprocessor that your server supports
and other information that you must consider when installing a microprocessor:
v Your server supports up to two microprocessors. With two microprocessors, your
v You might need to update the server BIOS code. Be sure to read the
v (Optional) Obtain an SMP-capable operating system. For a list of supported
v To order additional microprocessor options, contact your IBM reseller or IBM
v When you install the microprocessor in socket J6, you must also install the
v The microprocessor speeds are automatically set for this server; therefore, you
v If you need to replace a microprocessor, call for service.
v If your server supports a 400 MHz front-side bus, install only a microprocessor

server can operate as a symmetric multiprocessing (SMP) server. With SMP,
certain operating systems and application programs can distribute the processing
load between the microprocessors. If your server comes with one
microprocessor, you can install a second microprocessor.

removed from the heat sink or fan sink, do not touch the thermal grease on the
bottom of the heat sink or fan sink or set down the heat sink or fan sink.
Note: Removing the heat sink or fan sink from the microprocessor destroys the
even distribution of the thermal grease and requires replacing the thermal
grease. Setting down the heat sink or fan sink onto any surface when the
