[. . . ] 5V 1 En-19 MS-7681 Mainboard Buttons The mainboard provides the following buttons for you to set the computer’s function. This section will explain how to change your mainboard’s function through the use of button. OC Genie Button: TURBO1 This button is used to auto-overclock for the system. Press this button to enable the OC Genie function when the system is in power off state, meanwhile, the button will light and lock. And then the system will automatically detect the optimum values to overclock after booting the system. To disable the OC Genie function, please press the button again after power off the system, meanwhile, the button light will off and unlock, and the system will restore the default for next boot. Important • Please install the DDR3 1333 and up memory and equip better heat sink/ cooler with OC Genie function. € We do not guarantee the OC Genie overclocking range and the damages or risks caused by the OC Genie overclocking behavior. And we suggest you to save the OC Genie configuration to overclocking profile in BIOS for future using. Power Button: POWER1 This button is used to turn-on or turn-off the system. En-20 Voltage Check Point Voltage Check Point: FV1 This voltage check point set is used to measure the current CPU/ CPU_VTT/ CPU_ GFX/ DDR/ PCH voltage. CPU 1 CPU_GFX PCH GND 7 English CPU_VTT DDR GND 1 7 CPU GND CPU voltage: measure the current CPU voltage with CPU point and GND point by using a multimeter. 1 7 CPU_VTT GND CPU_VTT voltage: measure the current CPU_ VTT voltage with CPU_VTT point and GND point by using a multimeter. 1 7 CPU_GFX GND CPU_GFX voltage: measure the current CPU Integrated Graphic voltage with CPU_GFX point and GND point by using a multimeter. 1 7 DDR GND DDR voltage: measure the current DDR voltage with DDR point and GND point by using a multimeter. 1 7 PCH GND PCH voltage: measure the current PCH voltage with PCH point and GND point by using a multimeter. En-21 MS-7681 Mainboard LED Status Indicators CPU Phase LEDs Dual BIOS LED CPU Phase LEDs These LEDs indicate the current CPU power phase mode. Dual BIOS LED The Dual BIOS LED indicates the BIOS status during system power on. En-22 Jumper Clear CMOS Jumper: JBAT1 There is a CMOS RAM onboard that has a power supply from an external battery to keep the data of system configuration. With the CMOS RAM, the system can automatically boot OS every time it is turned on. If you want to clear the system configuration, set the jumper to clear data. JBAT1 1 1 English Keep Data Clear Data Important You can clear CMOS by shorting 1-2 pin while the system is off, then open it. [. . . ] – Power Technology This item allows you to select the Intel Dynamic Power technology mode. – C1E Support To enable this item to read the CPU power consumption while idle. – OverSpeed Protection Overspeed Protection function can monitor the current CPU draws as well as its power consumption. If it exceeds a certain level, the processor automatically reduces its clock speed. [. . . ]
