CHAPTER 2: HARDW ARE INSTALLATION
2.1 INSTALLING CENTRAL PROCESSING UNI T (CPU)
Special Notice:
Remo v e Pin Cap before installa tion, and m ake goo d preservation
for future use. When the CPU is remo ved, cov er the Pin Cap on the
empty so cket to ensure pin legs won’ t be da mag ed.

945GC-M7G / 945GC Micro 775
Step 2: Look for the triangular cut edge on socket, and the golden dot on
CPU should point forwards this triangular cut edge. The CPU will
fit only in the correct orientation.
Step 2-1:
Step 2-2:
Step 3: Hold the CPU down firmly, and then lower the lever to locked
position to complete the installation.
Step 4: 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 JCFAN1. This completes the installation.
