Hardware Installation This section will guide you through the installation of the motherboard. The topics covered in this section are: Preparing the motherboard ¾ Installing the CPU ¾ Installing the CPU fan ¾ Installing the memory Installing the motherboard Connecting cables and setting switches Safety Instructions To reduce the risk of fire, electric shock, and injury always follow basic safety precautions.
Preparing the Motherboard Installing the CPU Be very careful when handling the CPU. Make sure not to bend or break any pins within the socket. Hold the processor only by the edges and do not touch the bottom of the processor. Use the following procedure to install the CPU onto the motherboard. 1. Unhook the socket lever by pushing down and away from the socket. 2. Lift the load plate. There is a protective socket cover on the load plate to protect the socket when there is no CPU installed. 3.
Installing the Motherboard The sequence of installing the motherboard into the chassis depends on the chassis you are using and if you are replacing an existing motherboard or working with an empty chassis. It is recommended to secure the motherboard first before making all connections. Use the following procedure to install the I/O shield and secure the motherboard into the chassis. Be sure that the CPU fan assembly has enough clearance for the chassis covers to lock into place and for the expansion cards.
Connecting Cables and Setting Switches This section takes you through all the connections and switch settings necessary on the motherboard. This will include: Power Connections ¾ 24-pin ATX power (PWR1) ¾ 8-pin ATX 12V power (PWR2) Internal Headers ¾ Front panel ¾ USB Headers ¾ Audio ¾ Speaker ¾ COM FDD IDE Serial ATA II Chassis Fans Expansion slots CMOS jumper settings See Figure 1 on page 5 to locate the connectors and jumpers referenced in the following procedure.
Power Connections To support 2-way SLI, this motherboard has the following specific minimum power supply requirements: An SLI-Certified power supply. 6-pin and/or 8-pin PCI-E power connectors configured in either of the following configurations (see Figure 3): ¾ Two 6-pin (3x2) and two 8-pin (4x2) PCI-E power connectors ¾ Four 6-pin (3x2) PCI-E power connectors ¾ Two 6-pin (3x2) PCI-E power connectors 8-pin (4x2) PCI-E Connector Figure 3.
24-pin ATX Power (PWR1) PWR1 is the main power supply connector located along the edge of the board next to the DIMM slots. Make sure that the power supply cable and pins are properly aligned with the connector on the motherboard. Firmly plug the power supply cable into the connector and make sure it is secure. This connector is notched, do not force in. PWR1 connector Plug power cable from system power supply to PWR1 Board edge Figure 4. PWR1 Motherboard Connector Table 1.
8-pin ATX 12V Power (PWR2) PWR2, the 8-pin ATX 12V power connection, is used to provide power to the CPU. Align the pins to the connector and press firmly until seated. This connector is notched, do not force in. 1 5 GND 12V 4 8 Connecting IDE Hard Disk Drives IDE Connector Card Edge The IDE connector supports Ultra ATA 133/100/66 IDE hard disk drives. 1. Connect the blue connector (the cable end with a single connector) to the motherboard. 2.
Connecting Serial ATA Cables The Serial ATA II connector is used to connect the Serial ATA II device to the motherboard. These connectors support the thin Serial ATA II cables for primary storage devices. The current Serial ATA II interface allows up to 300MB/s data transfer rate. There are six serial ATA connectors on the motherboard that support RAID 0, RAID 1, RAID 5, RAID 0+1 and JBOD configurations. Connect the locking cable end to the motherboard connector.
Connecting Internal Headers Front Panel Header The front panel header on this motherboard is one connector used to connect the following four cables: (see Table 2 for pin definitions) PWRLED Attach the front panel power LED cable to these two pins of the connector. The Power LED indicates the system’s status. When the system is in S0 status, the LED is on. When the system is in S1, S3, S4, S5 status, the LED is off. Some chassis do not have all four cables.
