Upgrading the CPUs
CAUTION!
Allow time for the processor and heatsink to cool before touching either of them.
The Pentium III processors together with Level 2 cache chips are housed in a
protective cartridge called a SECC2. The SECC2 modules are attached to the
computer using a slot 1 interface. Vertical supports, retention pillars, are used to
keep the module fixed into place.
The design of the computer makes it a simple job to replace or upgrade
the processors. To do so, please refer to
Figure 1
and
Figure 5
and follow the
instructions below.
1. Read the warnings at the start of this chapter and ensure a static free
environment.
2. Remove the lid from the computer by removing the screws at the rear of the
case.
3. Locate the SECC2 module(s) or Termination card (
If upgrading from one
processor
) by referring to
Figure 1
if necessary.
4. Carefully pull back the tab of the retention mechanism marked B in
Figure 5
with
your left hand until the processor/Terminator card can be rotated out of the slot.
With your right hand, grasp the processor/Terminator card on the side closest to
the retention mechanism tab you are pulling back on, and rotate the one side of
the processor/terminator card out of the slot. Once that side is free, you can pull
the other side out of the slot.
5. You can now fit the additional or replacement SECC2 module and heatsink into
the slot 1 interface.
If the replacement Pentium III processor(s) is of a different speed (MHz) to the
previous one you will now have to configure the Processor speed in the BIOS, see
chapter 5.
