[. . . ] After restarting your computer, you will find "VIA HD Audio Deck" tool on your system. for Windows® XP / XP 64-bit OS: Please click "VIA HD Audio Deck" icon , and click "Speaker". Then you are allowed to select "2 Channel" or "4 Channel". Because the motherboard specifications and the BIOS software might be updated, the content of this manual will be subject to change without notice. [. . . ] To improve heat dissipation, remember to spray thermal grease between the CPU and the heatsink when you install the PC system. Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Take note of the following precautions before you install motherboard components or change any motherboard settings. Before you install or remove any component, ensure that the power is switched off or the power cord is detached from the power supply. Unplug the power cord from the wall socket before touching any component. to avoid damaging the motherboard components due to static electricity , NEVER place your motherboard directly on the carpet or the like. Also remember to use a grounded wrist strap or touch a safety grounded object before you handle components. Whenever you uninstall any component, place it on a grounded antistatic pad or in the bag that comes with the component. When placing screws into the screw holes to secure the motherboard to the chassis, please do not over-tighten the screws!Position the CPU directly above the socket such that the CPU corner with the golden triangle matches the socket corner with a small triangle. When the CPU is in place, press it firmly on the socket while you push down the socket lever to secure the CPU. After you install the CPU into this motherboard, it is necessary to install a larger heatsink and cooling fan to dissipate heat. You also need to spray thermal grease between the CPU and the heatsink to improve heat dissipation. Make sure that the CPU and the heatsink are securely fastened and in good contact with each other. For dual channel configuration, you always need to install two identical (the same brand, speed, size and chip-type) memory modules in the DDR3 DIMM slots to activate Dual Channel Memory Technology. It is not allowed to install a DDR or DDR2 memory module into DDR3 slot;otherwise, this motherboard and DIMM may be damaged. If you install only one memory module or two non-identical memory modules, it is unable to activate the Dual Channel Memory Technology. Please make sure to disconnect power supply before adding or removing DIMMs or the system components. It will cause permanent damage to the motherboard and the DIMM if you force the DIMM into the slot at incorrect orientation. Firmly insert the DIMM into the slot until the retaining clips at both ends fully snap back in place and the DIMM is properly seated. PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI interface. PCIE slots: PCIE1 (PCIE x1 slot) is used for PCI Express cards with x1 lane width cards, such as Gigabit LAN card, SATA2 card, etc. [. . . ] Before you enable Untied Overclocking function, please enter "Overclock Mode" option of BIOS setup to set the selection from [Auto] to [CPU, PCIE, Async. Therefore, CPU FSB is untied during overclocking, but PCI / PCIE buses are in the fixed mode so that FSB can operate under a more stable overclocking environment. Please refer to the warning on page 7 for the possible overclocking risk before you apply Untied Overclocking Technology. When you start up the computer, please press <F2> during the Power-On-Self-Test (POST) to enter BIOS Setup utility; otherwise, POST continues with its test routines. [. . . ]
