1-3 Installing the Memory Read the following guidelines before you begin to install the memory: •• Make sure that the motherboard supports the memory. It is recommended that memory of the same capacity, brand, speed, and chips be used. •• Always turn off the computer and unplug the power cord from the power outlet before installing the memory to prevent hardware damage. •• Memory modules have a foolproof design. A memory module can be installed in only one direction. If you are unable to insert the memory, switch the direction. Dual Channel Memory Configuration This motherboard provides two DDR3L memory sockets and supports Dual Channel Technology. After the memory is installed, the BIOS will automatically detect the specifications and capacity of the memory. The two DDR3L memory sockets are divided into two channels and each channel has one memory socket as following: Channel A: SODIMM_1 Channel B: SODIMM_2 Due to SoC limitations, read the following guidelines before installing the memory in Dual Channel mode. 1. If only one DDR3L memory module is to be installed, be sure to install it in the SODIMM_1 socket, and Dual Channel mode cannot be enabled if only one memory module is installed. 2. When enabling Dual Channel mode with two memory modules, it is recommended that memory of the same capacity, brand, speed, and chips be used for optimum performance. 1-4 Installing an Expansion Card Read the following guidelines before you begin to install an expansion card: •• Make sure the motherboard supports the expansion card. Carefully read the manual that came with your expansion card. •• Always turn off the computer and unplug the power cord from the power outlet before installing an expansion card to prevent hardware damage. 1-5 Back Panel Connectors PS/2 Keyboard/Mouse Port Use the upper port (green) to connect a PS/2 mouse and the lower port (purple) to connect a PS/2 keyboard.
