WARNING: Electrostatic Sensitive Device (ESD)
Static electricity can easily damage your motherb oard and will void your motherboard warran ty. Keep the motherboard
and other system components in their anti-static packaging until you are re ady to install them. Touch a grounded surface
before you remove any system component from its protective anti-s tatic packaging. Unpacking and installation should be
done on a grounded, anti-static mat. The operator should be wearing an anti-static wristband, grounded at the same
points as the anti-static mat. During configuration a nd installation touch a grounde d surface frequently to dis charge any
static electrical charge that may have built up in your body. Avoid touching the components when handling the
motherboard or a peripheral card . Handle the motherboa rd and peri pheral card s ei ther b y the edge s or b y the peri ph eral
card case-mounting bracket.
WARNING: Misplaced Jumper Damage
Incorrect jumpers and connectors settings may lead to damage to your motherboard and will void your motherboard
warranty. Please pay special attention to not connect these headers in the wrong direction. DO NOT change ANY jumpers
while the motherboard has power.

CPU Installation
This processor is intended to be professionally installed. Take proper electrostatics discharge (ESD)
precautions such as using appropriate ground strips, gloves, and ESD mats.
• Insert CPU into CPU socket and turn the screw to the lock position.
Note: Do not force the CPU into the socket. It may bend the pins and damage the CPU.
Installing the CPU Cooler
z -Insert the retention bracket through the screw hole from bottom side of motherboard.
-Match and place CPU cooler assembly on the top of CPU and retention bracket.
-Tighten the screws into the retention bracket.
Screw holes Retention bracket CPU cooler & Retention bracket
(rear side)
Note: Make sure CPU cooler assembly and CPU top surface are in total contact to avoid CPU
overheating problem which would cause the system to hang or unstable.
