G586OPC
Installing Upgrade CPUs
The G586OPC is equipped with a 321-pin Zero
Insertion Force (ZIF) socket at location U26 of the
system board. This socket is designed for easy removal
of the old CPU and easy insertion of the upgrade CPU.
The socket allows you to carefully place the new CPU
into its position. If you need to apply excessive force to
insert the CPU, the installation is being done incorrectly.
Warning:
Open the socket only if actually installing a CPU. The
warranty on the original CPU will be voided if the S/N
seal is broken.
Do not change any factory CPU speed jumper settings.
You do not need to change any jumpers to properly
install the 3.3V Pentium Upgrade Processor.
Before proceeding with the upgrade, take note of the
following. The microprocessor and heat sink may be hot
if the system has been running. To avoid the possibility
of a burn, power the system off and let the processor
and heat sink cool for 10 minutes.
The 321-pin ZIF socket consists of the four rows of pin
holes on each side. To prevent improper OverDrive
Processor installation, the ZIF socket has a Plug/Keying
mechanism. Several holes in the socket are plugged so
OverDrive Processors will go in only one way. If you
cannot easily insert the OverDrive Processor, verify that
pin 1 of the CPU is aligned with pin 1 of the socket. A
warning note — be extremely careful to match pin 1 of
the CPU with pin 1 of the socket. Only Intel's
OverDrive Processor is keyed to prevent improper
placement in the ZIF socket. Other Intel CPUs, as well
