1-3 Installing the CPU Read the following guidelines before you begin to install the CPU: •• Make sure that the motherboard supports the CPU. (Go to GIGABYTE's website for the latest CPU support list.) •• Always turn off the computer and unplug the power cord from the power outlet before installing the CPU to prevent hardware damage. •• Locate the pin one of the CPU. The CPU cannot be inserted if oriented incorrectly.
1-5 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.
Line Out Jack (Green) The default line out jack. Use this audio jack for a headphone or 2-channel speaker. This jack can be used to connect front speakers in a 4/5.1/7.1-channel audio configuration. Mic In Jack (Pink) The default Mic in jack. Microphones must be connected to this jack. To configure 7.1-channel audio, you have to use an HD front panel audio module and enable the multi-channel audio feature through the audio driver.
1/2) ATX_12V/ATX (2x2 12V Power Connector and 2x12 Main Power Connector) With the use of the power connector, the power supply can supply enough stable power to all the components on the motherboard. Before connecting the power connector, first make sure the power supply is turned off and all devices are properly installed. The power connector possesses a foolproof design. Connect the power supply cable to the power connector in the correct orientation.
5) BAT (Battery) The battery provides power to keep the values (such as BIOS configurations, date, and time information) in the CMOS when the computer is turned off. Replace the battery when the battery voltage drops to a low level, or the CMOS values may not be accurate or may be lost. You may clear the CMOS values by removing the battery: 1. Turn off your computer and unplug the power cord. 2. Gently remove the battery from the battery holder and wait for one minute.
8) F_PANEL (Front Panel Header) Connect the power switch, reset switch, speaker, and system status indicator on the chassis to this header according to the pin assignments below. Note the positive and negative pins before connecting the cables. 1 OS Switcher (X58A-OC) 1 SPEAK- SPEAK+ PLED+ PLEDPW+ PW- PWR_LED+ PWR_LEDPWR_LED- HD+ HDRESRES+ CICI+ Hard Drive Reset Activity LED Switch Power LED Chassis Intrusion Header F_PANEL Connects (H61M-D2)to the power switch on the chassis front panel.
10) F_USB1/F_USB2 (USB 2.0/1.1 Headers) The headers conform to USB 2.0/1.1 specification. Each USB header can provide two USB ports via an optional USB bracket. For purchasing the optional USB bracket, please contact the local dealer. 9 10 1 2 Pin No. 1 2 3 4 5 Definition Power (5V) Power (5V) USB DXUSB DYUSB DX+ Pin No. 6 7 8 9 10 Definition USB DY+ GND GND No Pin NC •• Do not plug the IEEE 1394 bracket (2x5-pin) cable into the USB header.
Chapter 2 BIOS Setup BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup, saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that allows the user to modify basic system configuration settings or to activate certain system features.
2-2 M.I.T. This section provides information on the BIOS version, CPU base clock, CPU frequency, memory frequency, total memory size, CPU temperature, Vcore, and memory voltage. Whether the system will work stably with the overclock/overvoltage settings you made is dependent on your overall system configurations. Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory and reduce the useful life of these components.
&& Uncore Ratio Allows you to set the CPU Uncore ratio. The adjustable range is dependent on the CPU being used. Displays the current CPU Uncore frequency. Allows you to determine whether to enable the Intel CPU Turbo Boost technology. Auto lets the BIOS automatically configure this setting.
&& Extreme Memory Profile (X.M.P.) (Note) Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance when enabled. Disabled Disables this function. (Default) Profile1 Uses Profile 1 settings. (Note) Profile2 Uses Profile 2 settings. && System Memory Multiplier Allows you to set the system memory multiplier. Auto sets memory multiplier according to memory SPD data.
`` PC Health Status && Reset Case Open Status Disabled Keeps or clears the record of previous chassis intrusion status. (Default) Enabled Clears the record of previous chassis intrusion status and the Case Open field will show "No" at next boot. && Case Open Displays the detection status of the chassis intrusion detection device attached to the motherboard CI header. If the system chassis cover is removed, this field will show "Yes", otherwise it will show "No".
2-3 System Information This section provides information on your motherboard model and BIOS version. You can also select the default language used by the BIOS and manually set the system time. && System Language Selects the default language used by the BIOS. Sets the system date. The date format is week (read-only), month, date, and year. Use to switch between the Month, Date, and Year fields and use the or key to set the desired value.
2-4 BIOS Features && Boot Option Priorities Specifies the overall boot order from the available devices. For example, you can set hard drive as the first priority (Boot Option #1) and DVD ROM drive as the second priority (Boot Option #2). The list only displays the device with the highest priority for a specific type. For example, only hard drive defined as the first priority on the Hard Drive BBS Priorities submenu will be presented here.
&& VGA Support Allows you to select which type of operating system to boot. Auto Enables legacy option ROM only. EFI Driver Enables EFI option ROM. (Default) This item is configurable only when Fast Boot is set to Enabled or Ultra Fast. && USB Support Disabled All USB devices are disabled before the OS boot process completes. Full Initial All USB devices are functional in the operating system and during the POST.
&& CSM Support Enables or disables UEFI CSM (Compatibility Support Module) to support a legacy PC boot process. Always Enables UEFI CSM. (Default) Never Disables UEFI CSM and supports UEFI BIOS boot process only. This item is configurable only when Windows 8 Features is set to Windows 8 or Windows 8 WHQL. && Boot Mode Selection Allows you to select which type of operating system to boot.
2-5 Peripherals && Initial Display Output Specifies the first initiation of the monitor display from the installed PCI Express graphics card or the onboard graphics. IGFX Sets the onboard graphics as the first display. PCIe 1 Slot Sets the graphics card on the PCIEX16 slot as the first display. (Default) && xHCI Mode Allows you to determine the operating mode for the xHCI controller in OS.
&& Audio Controller Enables or disables the onboard audio function. (Default: Auto) If you wish to install a 3rd party add-in audio card instead of using the onboard audio, set this item to Disabled. && Intel Processor Graphics Enables or disables the onboard graphics function. (Default: Enabled) Allows you to set the onboard graphics memory size. Options are: 32M~1024M. (Default: 64M) Allows you to allocate the DVMT memory size of the onboard graphics. Options are: 128M, 256M, MAX.
&& Parallel Port Enables or disables the onboard parallel port. (Default: Enabled) This item is configurable only when Parallel Port is set to Enabled. Selects an operating mode for the onboard parallel (LPT) port. Options are: Standard Parallel Port Mode (Default), EPP Mode (Enhanced Parallel Port), ECP Mode (Extended Capabilities Port), EPP Mode & ECP Mode. && Device Mode `` Realtek PCIe GBE Family Controller This sub-menu provides information on LAN configuration.
&& AC BACK Determines the state of the system after the return of power from an AC power loss. Memory The system returns to its last known awake state upon the return of the AC power. Always On The system is turned on upon the return of the AC power. Always Off The system stays off upon the return of the AC power. (Default) && Power On By Keyboard Allows the system to be turned on by a PS/2 keyboard wake-up event.
&& Save & Exit Setup Press on this item and select Yes. This saves the changes to the CMOS and exits the BIOS Setup program. Select No or press to return to the BIOS Setup Main Menu. && Exit Without Saving Press on this item and select Yes.
