4. Apply the proper amount of thermal compound to the CPU die and place
the heatsink on top of the CPU. Make sure the heatsink sits completely flat
on the CPU. If not completely flat, the space between the two will degrade
the heat dissipation function of the heatsink, which may cause the proces-
sor to overheat.
5. Secure the heatsink by locking each retention clip into its proper position.
When correctly installed, the clips should *click* into place and the three
black tabs on the CPU retention pieces should protrude fully through the
corresponding holes on the each clip. See Figures 5-2a and 5-2b for dia-
grams of the retention clips and the heatsink installation procedure.
IMPORTANT: Please note that special, new silver heat sink retention clips
must be used with all Xeon 533 MHz FSB (front side bus) 604-pin proces-
sors. These new retention clips have “604P” clearly marked on them. Using
the old clips will not keep the proper amount of pressure applied and may
cause the processor to overheat. In addition, you should not use these
new retention clips with Xeon 400 MHz FSB processors (even in 604-pin
CPU sockets) as they will be too tight and may damage the CPU socket.
6. If installing two processors, repeat these steps to install the second
processor in the CPU #2 slot.

Warning!
Make sure you lift the lever completely when
installing the CPU. If the lever is only partly raised, damage
to the socket or CPU may result.
