5-33.  Align pin 1 of the CPU with pin 1 
of the socket. Once aligned, carefully 
place the CPU into the socket.  Do not 
drop the CPU on the socket, move the 
CPU horizontally or vertically or rub the 
CPU against the socket or against any 
pins of the socket, which may damage 
the CPU and/or the socket.
4. With the CPU inserted into the 
socket, inspect the four corners of the 
CPU to make sure that it is properly in-
stalled and fl ush with the socket.  Then, 
gently lower the silver CPU retention 
plate into place.
5. Carefully press the CPU socket le-
ver down until it locks into its retention 
tab.  For a dual-CPU system, repeat 
these steps to install another CPU into 
the CPU#2 socket (and into CPU#2, 
#3 and #4 sockets for a quad-CPU 
confi guration).      
Note: in dual-CPU configurations,  
only the CPU1 and CPU2 DIMM slots 
are addressable for a maximum of 16 
GB memory.
