CHAPTER 2: HARDWARE INSTALLATION
A770 A2G+
2.1 I
NSTALLING CENTRAL PROCESSING UNIT (CPU)
Step 1: Remove the socket protection cap.
Step 2: Pull the lever toward direction A from the socket and then raise the
lever up to a 90-degree angle.
Step 3: Look for the white triangle on socket, and the gold triangle on
CPU should point towards this white triangle. The CPU will fit only
in the correct orientation.

Motherboard Manual
Step 4: Hold the CPU down firmly, and then close the lever toward direct
B to complete the installation.
Step 5: Put the CPU Fan on the CPU and buckle it. Connect the CPU
FAN power cable to the CPUFAN. This completes the installation.
Note: Please update the BIOS to the latest version while using AM2+ CPUs. Due to the latest CPU
transition, you may encounter the situation that the new system failed to boot while using new
AM2+ CPUs. In this case, please install one standard AM2 CPU to boot your system, and
update the latest BIOS from our website for AM2+ CPUs support.
