Chapter 2 Hardware Setup This chapter provides you with the information about hardware setup procedures. While doing the installation, be careful in holding the com- ponents and follow the installation procedures. For some components, if you install in the wrong orientation, the components will not work prop- erly.
2.2 CPU (Central Processing Unit) The mainboard supports Intel® Core 2 Duo/Core Duo/Core Solo pro- cessors. 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.
Page 18
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. Release the metal clips on the retention mechanism. Note Mainboard photos shown in this section are for demonstration only and may differ from the actual look of your mainboard.
Page 19
Mount the cooler set (fan & heat sink bundled) on top of the CPU and fit it into the retention mechanism. Secure the metal clips back to the retention mechanism. Connect the fan power cable from the mounted fan to the 3-pin fan power connector on the mainboard.
2.3 Memory The mainboard provides one 240-pin non-ECC DDRII 533/667 DIMM slot and supports up to 2GB system memory.
