Replacing Or Adding A Processor - Gateway 8400 System Manual

Replacing or adding a processor

The system is compatible with the Intel
processors with 100 MHz front-side bus (FSB). As many as four processors may
be installed in the system (they must have the same processor and FSB speed).
Processor and FSB speed are automatically detected by the system. Processors
must be installed in order, from slot 1 through slot 4 and a Voltage Regulator
Module (VRM) must be installed for each processor added to the system.
Whenever processors are installed, the most current version of the BIOS
should be installed as well (see "Updating the BIOS" on page 73).
When adding or replacing a processor, order a processor upgrade kit from
Gateway. The kit includes the processor, a heatsink, and a VRM.
Caution
To replace a processor:
1
Observe the safety and ESD precautions in "Preventing static electricity
discharge" on page 15.
2
Turn off the system and disconnect the power cord(s), modem cord (if
installed) and all other external peripheral devices.
3
Remove the back access panel. (See "Removing the side panels" on
page 18.)
4
Loosen the captive screw securing the memory module retention bracket
to the chassis, then swing the retention bracket out from the chassis and
remove it.
5
Remove the foam cover from the electronics bay. (Do not remove the
plastic air baffle attached to the foam cover.)
48
Replacing and Adding System Components
A heatsink must be installed on each processor. Installing
a processor without a heatsink could result in damage to,
or failure of, the processor.
