5. Use a “Slot head” screw driver to turn the CPU locking screw on the CPU socket 180
degree counter clockwise to unlock position.
6. Now you are ready to install the CPU. Do not touch the CPU pins directly with fingers.
Use a suction tool to handle the CPU if possible. Or else, only handle the CPU by the
edge of PCB.
7. Make sure the surface of the CPU is clean and shinny. This is very important
especially using one CPU which has been installed and having thermal grease residual
on top of the chip. Remove all residuals in this case.
8. Drop the CPU into the socket with the pin 1 of CPU sitting in pin 1 of the socket.
.
9. Make sure the CPU is sitting properly by slightly rocking it, then lock the CPU locking
screw on the socket by turning it 180 degree clockwise.

already. Remove the foil which protects the compound. Carefully put back the heat
sink covering the CPU, making sure the fin portion of the heat sink goes into the space
as before it was taken out, and fasten the four screws by evenly applying the
approximately same few turns one by one. If a heat sink is reused, make sure to clean
the thermal compound completely, and reapply ample compound. A silicon thermal
pad can be used too.
