DDR SDRAM is a type of SDRAM that supports data transfers on both edges of each clock cycle (the rising and falling edges), effectively doubling the memory chip's data throughput. 8 Chapter 2: Motherboard Installation Memory Module Installation Procedure These modules can be installed with up to 2 GB system memory. Refer to the following to install the memory module. 1. Push down the latches on both sides of the DIMM socket. 2. Align the memory module with the socket. There is a notch on the DIMM socket that you can install the DIMM module in the correct direction. Match the cutout on the DIMM module with the notch on the DIMM socket. 3. Install the DIMM module into the socket and press it firmly down until it is seated correctly. The socket latches are levered upwards and latch on to the edges of the DIMM. 4. Install any remaining DIMM modules. 9 Motherboard User's Guide Jumper Settings Connecting two pins with a jumper cap is SHORT; removing a jumper cap from these pins, OPEN. CLR_CMOS1: Clear CMOS Jumper Use this jumper to clear the contents of the CMOS memory. You may need to clear the CMOS memory if the settings in the Setup Utility are incorrect and prevent your motherboard from operating. To clear the CMOS memory, disconnect all the power cables from the motherboard and then move the jumper cap into the CLEAR setting for a few seconds. Function Jum per Clear CMOS Short Pins 1-2 Normal Short Pins 2-3 Install The Motherboard Install the motherboard in a system chassis (case). The board is a Micro ATX size motherboard. You can install this motherboard in an ATX case. Make sure your case has an I/O cover plate matching the ports on this motherboard. Install the motherboard in a case. Follow the case manufacturer's instructions to use the hardware and internal mounting points on the chassis. 10 Chapter 2: Motherboard Installation Connect the power connector from the power supply to the PWR1 connector on the motherboard. PWR2 is a +12V connector for CPU Vcore power. If there is a cooling fan installed in the system chassis, connect the cable from the cooling fan to the SYS_FAN1 fan power connector on the motherboard. Connect the case switches and indicator LEDs to the PANEL1 header.

Users please note that when installing 24-pin power cable, the latches of power cable and the PWR1 connector match perfectly. Note: Users please note that the 20-pin and 24-pin power cables can both be connected to the PWR1 connector. While connceting the 20-pin power cable, just align the 20-pin power cable with the pin 1 of the PWR1 connector. However, using 20-pin power cable may cause the system the unbootable or unstable problem because of insufficient electricity. The minimum recommended power is 300W for a fully-configured system.

Via a specific audio cable, you can connect the SPDIFO1 header (S/PDIF output) on the motherboard to the S/PDIF digital input on the external speakers or AC Decode devices. Pin 1 3 Signal SPDIF OUT KEY Pin 2 4 Signal +5V GND 14 Chapter 2: Motherboard Installation Install Other Devices Install and connect any other devices in the system following the steps below. Floppy Disk Drive The motherboard ships with a floppy disk drive cable that can support one or two drives. Drives can be 3.5" or 5.25" wide, with capacities of 360 K, 720 K, 1.2 MB, 1.44 MB, or 2.88 MB. Install your drives and connect power from the system power supply. Use the cable provided to connect the drives to the floppy disk drive connector FDD1. IDE Devices IDE devices include hard disk drives, high-density diskette drives, and CDROM or DVD-ROM drives, among others. The mainboard ships with an IDE cable that can support one or two IDE devices. If you connect two devices to a single cable, you must configure one of the drives as Master and one of the drives as Slave. The documentation of the IDE device will tell you how to configure the device as a Master or Slave device. The Master device connects to the end of the cable. Install the device(s) and connect power from the system power supply. Use the cable provided to connect the device(s) to the Primary IDE channel connector IDE1 on the motherboard. 15 Motherboard User's Guide If you want to install more IDE devices, you can purchase a second IDE cable and connect one or two devices to the Secondary IDE channel connector IDE2 on the motherboard. If you have two devices on the cable, one must be Master and one must be Slave. Serial ATA Devices The Serial ATA (Advanced Technology Attachment) is the standard interface for the IDE hard drives, which is designed to overcome the design limitations while enabling the storage interface to scale with the growing media rate demands of PC platforms. It provides you a faster transfer rate of 150 MB/s. If you have installed a Serial ATA hard drive, you can connect the Serial ATA cables to the Serial ATA hard drive or the connector on the motherboard. On the motherboard, locate the Serial ATA connectors SATA1-2, which support new Serial ATA devices for the highest data transfer rates, simpler disk drive cabling and easier PC assembly. It eliminates limitations of the current Parallel ATA interface, but maintains register compatibility and software compatibility with Parallel ATA. Analog Audio Input Header If you have installed a CD-ROM drive or DVD-ROM drive, you can connect the drive audio cable to the onboard sound system. 16 Chapter 2: Motherboard Installation When you first start up your system, the BIOS should automatically detect your CD-ROM/DVD drive. If it doesn't, enter the Setup Utility and configure the CD-ROM/DVD drive that you have installed. On the motherboard, locate the 4-pin header CD_IN1.

Secure the metal bracket of the card to the system chassis with a screw. PCI-E1 (PCI-Express x16) Slot You can install external PCI Express graphics cards in the PCI-E1 (PCIExpress x16) slot. PCI1-2 Slots You can install the 32-bit PCI interface expansion cards in the slots. CNR Slot You can install CNR (Communications and Networking Riser) cards with LAN, Modem and Audio functions in this slot. 18 Chapter 3: BIOS Setup Utility Chapter 3 BIOS Setup Utility Introduction The BIOS Setup Utility records settings and information of your computer, such as date and time, the type of hardware installed, and various configuration settings. Your computer applies the information to initialize all the components when booting up and basic functions of coordination between system components. If the Setup Utility configuration is incorrect, it may cause the system to malfunction. It can even stop your computer booting properly. If it happens, you can use the clear CMOS jumper to clear the CMOS memory which has stored the configuration information; or you can hold down the Page Up key while rebooting your computer. Holding down the Page Up key also clears the setup information. You can run the setup utility and manually change the configuration. You might need to do this to configure some hardware installed in or connected to the motherboard, such as the CPU, system memory, disk drives, etc. Running the Setup Utility Every time you start your computer, a message appears on the screen before the operating system loading that prompts you to "Hit if you want to run SETUP". Whenever you see this message, press the Delete key, and the Main menu page of the Setup Utility appears on your monitor. If you manually clear CMOS, you need to press the F1 key that enters the Main menu page of the Setup Utility.
