3. Position the CPU above the ZIF socket. Make sure pin 1 of the
CPU is aligned with pin 1 of the socket. Lower the chip until the
pins are inserted properly in their corresponding holes. Remember
that very little force is needed to install the CPU. If the CPU is not
easily inserted, verify whether or not pin 1 of the CPU is aligned
with pin 1 of the socket. Applying too much pressure can damage
the CPU or the socket.

4. Push the handle down until the handle locks into place. The top
plate will slide forward. You will feel some resistance as the pres-
sure starts to secure the CPU in the socket. This is normal and will
not damage the CPU. However, if the handle is not completely
closed, damage to the CPU and/or system board may result.
Clearance Requirements
Your CPU comes with a heat sink mounted on top. To maintain proper
airflow once the CPU is installed on the system board, the CPU and
heatsink require certain space clearances.
The clearance above the CPU' s fan/heat sink must be at least 0.4
inches. The clearance on at least 3 of 4 sides of the CPU must be at
least 0.2 inches. The cables (for floppy drive, hard drive, CD-ROM, etc.)
must be routed clear of the CPU and its airspace.
