Installing Upgrade Cpus - DFI G486VPA User Manual

G486VPA

Installing Upgrade CPUs

The G486VPA is equipped with a 237-pin Zero
Insertion Force (ZIF) socket at location U27 of the
system board. This socket enables you to remove the
old CPU and insert the upgrade CPU easily. 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. Installation of an OverDrive Processor
will not affect the original system warranty.
The 237-pin ZIF socket consists of the four rows of pin
holes on each side. To avoid improper installation, the
ZIF socket is designed with a Plug/Keying mechanism.
There are several holes in the socket that are plugged so
the CPU will only go in one way. If you are unable to
easily insert the CPU, please verify that pin 1 of the
CPU is being plugged into pin 1 of the socket. Pin one
is located as shown on the next page.
Caution:
You will need to change the CPU-type jumper settings.
(Please see the previous pages of this manual.)
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.
