7 Chapter 2 Installing the Motherboard Safety Precautions • • • • • Follow these safety precautions when installing the motherboard Wear a grounding strap attached to a grounded device to avoid damage from static electricity Discharge static electricity by touching the metal case of a safely grounded object before working on the motherboard Leave components in the static-proof bags they came in Hold all circuit boards by the edges.
8 Do not over-tighten the screws as this can stress the motherboard. Checking Jumper Settings This section explains how to set jumpers for correct configuration of the motherboard. Setting Jumpers Use the motherboard jumpers to set system configuration options. Jumpers with more than one pin are numbered. When setting the jumpers, ensure that the jumper caps are placed on the correct pins. The illustrations show a 2-pin jumper. When the jumper cap is placed on both pins, the jumper is SHORT.
9 Checking Jumper Settings The following illustration shows the location of the motherboard jumpers. Pin 1 is labeled. Name Type Description Setting (default) 1-2: NORMAL CLR_CMOS 3-pin Clear CMOS 1 2-3: CLEAR Before clearing the CLR_CMOS CMOS, make sure to turn off the system. To avoid the system unstability after clearing CMOS, we recommend users to enter the main BIOS setting page to “Load Default Settings” and then “Save Changes and Exit”.
10 Installing Hardware Installing the Processor Caution: When installing a CPU heatsink and cooling fan make sure that you DO NOT scratch the motherboard or any of the surface-mount resistors with the clip of the cooling fan. If the clip of the cooling fan scrapes across the motherboard, you may cause serious damage to the motherboard or its components. On most motherboards, there are small surface-mount resistors near the processor socket, which may be damaged if the cooling fan is carelessly installed.
11 CPU Installation Procedure The following illustration shows CPU installation components. 1 2 3 4 5 Install your CPU. Pull up the lever away from the socket and lift up to 90-degree angle. Locate the CPU cut edge (the corner with the pin hold noticeably missing). Align and insert the CPU correctly. Press the lever down and apply thermal grease on top of the CPU. Put the CPU Fan down on the retention module and snap the four retention legs of the cooling fan into place.
12 Installation Procedure Refer to the following to install the memory modules. 1 2 3 4 5 6 This motherboard supports unbuffered DDR3 SDRAM only. Push the latches on each side of the DIMM slot down. Align the memory module with the slot. The DIMM slots are keyed with notches and the DIMMs are keyed with cutouts so that they can only be installed correctly. Check that the cutouts on the DIMM module edge connector match the notches in the DIMM slot.
13 Expansion Slots Installing Add-on Cards The slots on this motherboard are designed to hold expansion cards and connect them to the system bus. Expansion slots are a means of adding or enhancing the motherboard’s features and capabilities. With these efficient facilities, you can increase the motherboard’s capabilities by adding hardware that performs tasks that are not part of the basic system.
14 Follow these instructions to install an add-on card: 1 2 3 Remove a blanking plate from the system case corresponding to the slot you are going to use. Install the edge connector of the add-on card into the expansion slot. Ensure that the edge connector is correctly seated in the slot. Secure the metal bracket of the card to the system case with a screw.
15 Connecting Optional Devices Refer to the following for information on connecting the motherboard’s optional devices: SATA1~6: Serial ATA connectors These connectors are used to support the new Serial ATAIII devices for the highest data transfer rates (6.0 Gb/s), simpler disk drive cabling and easier PC assembly. It doubles the transfer rate of current SATA 3.0Gb/s interface.
16 F_USB1~2: Front Panel USB 2.0 headers The motherboard has six USB 2.0 ports installed on the rear edge I/O port array. Additionally, some computer cases have USB 2.0 ports at the front of the case. If you have this kind of case, use auxiliary USB 2.0 connector to connect the frontmounted ports to the motherboard. Unlike F_USB2 in this mainboard, F_USB1 supports EZ Charger technology, provides 3 times current than general USB port in off mode for USB devices.
17 USB3F: Front Panel USB 3.0 header This Motherboard implements one USB 3.0 header supporting 2 extra front USB 3.0 ports, which delivers 5Gb/s transfer rate.
18 LPT: Onboard parallel port Header This is a header that can be used to connect to the printer, scanner or other devices.
19 Installing a SATA Hard Drive This section describes how to install a SATA hard drive. About SATA Connectors Your motherboard features six SATA connectors supporting a total of six drives. SATA refers to Serial ATA (Advanced Technology Attachment) is the standard interface for the IDE hard drives which are currently used in most PCs. These connectors are well designed and will only fit in one orientation.
20 Connecting I/O Devices The backplane of the motherboard has the following I/O ports: PS/2 mouse and keyboard combo connector Connect the PS/2 Keyboard or PS/2 Mouse to the PS/2 combo port. USB 2.0 Ports Use the USB 2.0 ports to connect USB 2.0 devices. USB 3.0 Ports Use the USB 3.0 ports to connect USB3.0 devices. LAN Port Connect an RJ-45 jack to the LAN port to connect your computer to the network. HDMI Port (DVI port optional) Connect the HDMI port to the HDMI devices.
21 Connecting Case Components After you have installed the motherboard into a case, you can begin connecting the motherboard components. Refer to the following: 1 Connect the CPU cooling fan cable to CPU_FAN. 2 Connect the standard power supply connector to ATX_POWER. 3 Connect the case switches and indicator LEDs to the F_PANEL. 4 Connect the system cooling fan connector to SYS_FAN. 5 Connect the auxiliary case power supply connector to ATX12V. 6 Connect the case speaker cable to SPK.
22 Connecting 4-pin power cable The ATX12V4P power connector is used to provide power to the CPU. When installing 4-pin power cable, the latches of power cable and the ATX12V4P match perfectly. 4-pin power cable CPU_FAN: Cooling FAN Power Connector Pin 1 2 3 4 Function Signal Name GND +12V System Ground Power +12V Sense Sensor PWM CPU FAN control Users please note that the fan connector supports the CPU cooling fan of 1.1A~2.2A (26.4W max.) at +12V.

63 Chapter 7 Trouble Shooting Start up problems during assembly After assembling the PC for the first time you may experience some start up problems. Before calling for technical support or returning for warranty, this chapter may help to address some of the common questions using some basic troubleshooting tips. a) System does not power up and the fans are not running. 1.Disassemble the PC to remove the VGA adaptor card, DDR memory, LAN, USB and other peripherals including keyboard and mouse.
64 2. From the BIOS setting, try to disable the Smartfan function to let the fan run at default speed. Doing a Load Optimised Default will also disable the Smartfan. Start up problems after prolong use After a prolong period of use your PC may experience start up problems again. This may be caused by breakdown of devices connected to the motherboard such as HDD, CPU fan, etc. The following tips may help to revive the PC or identify the cause of failure. 1. Clear the CMOS values using the CLR_CMOS jumper.
If fail, contact RMA CLR CMOS and restart. Yes Halt at POST screenΛ Yes Check if monitor has display Yes Check if Power Supply Unit (PSU) is working Power Bu on is pressed but PC fails to start. need to CLRCMOS. HDD problem.
