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.

5. Secure the heatsink by locking the retention clips into their proper posi-

tion. When correctly installed, the retention clips should *click* into place

and the three black tabs on the CPU retention pieces should protrude fully

through the corresponding holes on the retention clips. See Figures 5-2a

and 5-2b for diagrams of the retention clips and the heatsink installation

procedure.

6. If installing two processors, repeat these steps to install the second

processor in the CPU #2 slot.

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.

See Figure 5-2a.
