Take care when installing processor as it has very fragile connector pins below the
processor and can bend and break if inserted improperly.
Heatsink Retention Frame and Back Plate Installation
After you are done installing the processor, you should proceed to installing the heatsink. Heatsink
will ensure that the processor does not overheat and continues to operate at maximum
performance for as long as you own it. Overheated processor may damage the motherboard.
The back plate assembly prevents excessive motherboard flexing in the area near the processor
and provides a base for the installation of the heatsink retention frame and heatsink.
Because there are many different types of heatsinks available from many different manufacturers,
a lot of them have their own method of installation. For the safest method of installation and
information on choosing the appropriate heatsink, please refer to AMD's website at
http://www.amd.com.
The following diagram will illustrate how to install the most common CPU heatsink retention frame
and back plates:
1) Remove the adhesive cover from the back plate.
2) Align the back plate screw bolts to the holes around processor socket on the back of
motherboard.
3) Align the heatsink retention frame to the back plate screw bolts on the front of
motherboard.
4) Insert screws to fasten the retention frame and back plate.
