CHAPTER 2: HARDWARE INSTALLATION
2.1 INSTALLING 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.
A740G M2+
Step 3: Look for the white tri angle on socket, and the gold triangle on
CPU should point towards this white tri angle. The CPU will fit only
in th e cor r ec t or i en tatio n.

Motherboard Manual
Step 4: Hold the CPU down firmly, and then close the lever toward direct
B to complete the insta llation.
Step 5: Put th e CP U Fan on t he CP U and bu c kl e it . Co nn ec t the CPU
FAN power cable to the JCFAN1. Thi s completes the installation.
Note: Please update the B IOS to the latest version wh ile using AM2+ CP Us . Due to the latest CPU
transition, you may encounter the sit uation that the new system fail ed to boot while using new
AM2+ CPUs. In this case, please i nstall one standar d AM2 CPU to boot your s ystem, and
update the latest BIOS from our website f or AM2+ CPUs support.
