Our products are under continual improvement and we reserve the right to make changes without notice. The openings on the enclosure are for air convection hence protects the equipment from overheating. [. . . ] AtX 4-Pin Power Connector: JPWr2 this 4-Pin power connector is used to provide power to the CPU. * Make sure that all the connectors are connected to proper atX power supplies to ensure stable operation of the mainboard. IDE Connector: iDE1 this connector supports iDE hard disk drives, optical disk drives and other iDE devices. IMPOrtant if you install two iDE devices on the same cable, you must configure the drives to cable select mode or separately to master / slave mode by setting jumpers. IMPOrtant Please do not fold the Serial ata cable into 0-degree angle. Fan Power Connectors: CPUFan, SYSFan1 the fan power connectors support system cooling fan with +12V. When connecting the wire to the connectors, always note that the red wire is the positive and should be connected to the +12V; the black wire is ground and should be connected to gnD. If the mainboard has a System hardware Monitor chipset onboard, you must use a specially designed fan with speed sensor to take advantage of the CPU fan control. MS-7623 S/PDiF-Out Connector: JSP1 this connector is used to connect S/PDiF (Sony & Philips Digital interconnect Format) interface for digital audio transmission. Front Panel Connectors: JFP1, JFP2 these connectors are for electrical connection to the front panel switches and lEDs. Serial Port Connector: JCOM1 this connector is a 16550a high speed communication port that sends/receives 16 bytes FiFOs. Front Panel audio Connector: JaUD1 this connector allows you to connect the front panel audio and is compliant with intel® Front Panel i/O Connectivity Design guide. Front USB Connector: JUSB1, JUSB2 this connector, compliant with intel® i/O Connectivity Design guide, is ideal for connecting high-speed USB interface peripherals such as USB hDD, digital cameras, MP3 players, printers, modems and the like. Please refer to the tPM security platform manual for more details and usages. The system will record this status and show a warning message on the screen. To clear the warning, you must enter the BiOS utility and clear the record. 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. IMPOrtant You can clear CMOS by shorting 2-3 pin while the system is off. Parallel Port header: JlPt1 this connector is used to connect an optional parallel port bracket. APS lED Status indicator: lED1 (Optional) these aPS (active Phase Switching) lED indicates the current CPU power phase mode. [. . . ] * remember to disable Spread Spectrum if you are overclocking because even a slight jitter can introduce a temporary boost in clock speed which may just cause your overclocked processor to lock up. Load Optimized Defaults You can load the default values provided by the mainboard manufacturer for the stable performance. IMPorTanT Si vous installez deux dispositifs iDe sur un même câble, vous devez configurer le second dans le mode câble sélection ou dans le mode master / slave séparément en configurant les cavaliers. Cet article vous permet de déterminer le timing de la transition de raS (row address strobe) à caS (column address strobe). [. . . ]
