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 diff erent types of pin cap. Please refer below
instruction to r emove the pin cap.
Step 1: Pull the socket locking lever out from the socket and then raise
the lever up.
Step 2: Remove the Pin Cap.
6
Hi-Fi Z77X
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: Hold the CPU down firmly, and then lower the lever to locked
position to complete the installation.
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.
