Hardware Setup CPU (Central Processing Unit) The mainboard supports Intel ® Core 2 Duo/ Core Duo/ Core Solo/ Celeron M/ Celeron LV 423 BGA (with BGA Passive Cooler) processors in Socket M. When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating. If you do not have the heat sink and cooling fan, contact your dealer to purchase and install them before turning on the computer. Important 1.
MS-9642 Mainboard CPU & Cooler Set Installation 1. Place the CPU on top of the socket. Make sure to align the gold arrow on the CPU with the arrow key on the socket. 2. Push the CPU down until its pins securely fit into the socket. 3. On the front end of the CPU socket is a locking mechanism designed into the form of a screw. Make sure that you actuate or deactuate this mechanism with a screwdriver before and after installing the CPU. 4. Release the metal clips on the retention mechanism.
Hardware Setup 5. Mount the cooler set (fan & heatsink bundled) on top of the CPU and fit it into the retention mechanism. 6. Secure the metal clips back to the retention mechanism. 7. Connect the fan power cable from the mounted fan to the 3-pin fan power connector on the mainboard.
