Installing / removing processor
Replacing the processor
You can replace the processor in the slot of the first processor. The system board can be upgraded
by a second processor if it is inserted into the slot for the second processor.
If the system board only has one processor (inserted into the slot for the first processor (CPU 0)), a
terminating board is installed in the slot for the second processor.
!
You may only use processors of the same type on the system board (e.g. only Pentium II
or only Pentium III). The second processor must have the same clock rate (working and
FSB clock frequency) as the first.
If processors with different FSB clock frequencies are used, the board is held in reset and
the FSB mismatch LED lights up.
A suitable multiprocessor operating system must be used if dual operation is required.
Installing the processor
i
If you wish to upgrade the system with a new processor, the processor bracket on the
system board may need to be replaced beforehand. Should it be necessary to replace the
bracket, please contact our customer service center.
Depending on the design of the processor housing, the heat sink can be moved on the
processor and the processor in the bracket. This floating suspension in the installed state
ensures reliable contact between the processor and the heat sink. Detents in the bracket
prevent the processor from slipping out.
If the heat sink on the processor can be moved, then it must also be possible to move the
mounted processor in the bracket. This ensures optimum cooling.
If you replace the processor, grasp the processor housing by the processor and the heat
sink.
