Installing an additional microprocessor
The following notes describe the type of microprocessor that the server supports
and other information that you must consider when installing a microprocessor:
v The server supports certain Intel Xeon dual-core or quad-core flip-chip land grid
array 771 (FC-LGA 771) microprocessors, which are designed for the LGA771
socket. See http://www.lenovo.com/accessories for a list of supported
microprocessors.
Important: Dual-core and quad-core microprocessors are not interchangeable
and cannot be used in the same server. For example, if the server has a
dual-core microprocessor, you cannot install a quad-core microprocessor as the
second microprocessor. Use the Configuration/Setup Utility program to determine
the type and speed of the microprocessor that is currently installed in the server.
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 cache size and type, front-side bus
frequency, and the same clock speed. Microprocessor internal and external clock
frequencies must be identical.
v When you install an additional microprocessor in microprocessor connector 2,
you must also install the voltage regulator module (VRM), which comes with the
microprocessor, in the VRM connector.
v Read the documentation that comes with the microprocessor to determine
whether you must update the basic input/output system (BIOS) code for the
server. To download the most current level of BIOS code and many other code
updates for your server:
1. Go to: http://www.lenovo.com/support.
2. Enter your product number (machine type and model number) or select
Servers from the Select your product list.
3. Select Servers from the Brand list.
4. From Family list, select ThinkServer RD120, and click Continue.
5. Click Downloads and drivers to download firmware updates.
v (Optional) Obtain an SMP-capable operating system. For a list of supported
operating systems and optional devices, go to http://www.lenovo.com/support/.
v To order additional microprocessors, contact your Lenovo 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.
The following illustration shows the microprocessor connector locations and other
microprocessor-related components on the system board.
