To prevent damage to the CPU, CPU socket, or main board, ensure that the securing rod 
on the CPU socket is fully open before you install the CPU in the socket. 
 
When you close the securing rod, do not exert excessive force or touch any components 
and gild pins on the CPU. 
 
Do not move the CPU if it is not correctly placed to avoid any twisted pins. Lift the CPU 
until it is out of the socket, and then place it in the socket properly. 
Keep CPUs straight down and slide the CPUs in CPU sockets. See step (1) in Figure 
5-54. 
Align the triangle mark on the CPU with the triangle mark on the CPU socket to ensure 
that the CPU is properly installed. Figure 5-55 shows a CPU that is incorrectly place.
