CHAPTER 2: HARDWARE INSTALLATION
2.1 I
NSTALLING CENTRAL PROCESSING UNIT (CPU)
Notice:
1. Remove Pin Cap before installation, and make good preservation for future use.
When the CPU is removed, cover the Pin Cap on the empty socket to ensure pin
legs won’t be damaged.
2. The motherboard might equip with two different types of pin cap. Please refer
below instruction to remove the pin cap.
Step 1: Pull the socket locking lever out from the socket then raise the
lever and load plate to the fully open position.
Step 2: Remove the Pin Cap.

Step 3: Hold processor with your thumb and index fingers, oriented as
shown. Align the notches with the socket. Lower the processor
straight down without tilting or sliding the processor in the socket.
Step 4: Close the load plate. Pressing down on the load plate, close and
engage the socket lever.
Step 5: Put the CPU Fan and heatsink assembly on the CPU and buckle it
on the retention frame. Connect the CPU FAN power cable into
the CPU_FAN1 to complete the installation.
