Installing an Upgrade/Overdrive Processor
Contact your authorized reseller for more details.
CAUTION If you install a processor other than a Pentium Overdrive processor,
ensure that your Vectra PC supports it. Refer to the table below for more
information.
CAUTION If you install a 120 MHz processor or greater, add a drop of special
‘thermal compound’ between the processor and the heat sink when
replacing the processor. Contact your reseller to obtain the thermal
compound. Failing to add the thermal compound could result in damage
to the processor.
If you use an AMD, Intel P55, or Intel Vcc VRE processor, it is supplied
with its own Voltage Regulator Module (VRM), which must be installed
with the processor. The VRM ensures that the processor is provided
with the correct voltage.
1 Disconnect the computer power cords from the power outlets, and
disconnect the PC from any telecommunications network.
2 Remove the computer’s cover and lift the power supply from it’s
seating as described in “Moving and Replacing the Power Supply”, on
page 16.
