[. . . ] If you nstall two IDE devces on the same cable, you must configure the drves separately to master / slave mode by settng jumpers. Each connector can connect to one Seral ATA devce. To clear the warnng, you must enter the BIOS utlty and clear the record. The fan power connectors support system coolng fan wth +12V. When connectng the wre to the connectors, always note that the red wre s the postve and should be connected to the +12V; the black wre s Ground and should be connected to GND. If the manboard has a System Hardware Montor chpset on-board, you must use a specally desgned fan wth speed sensor to take advantage of the CPU fan control. You can nstall Control Center utlty that wll automatcally control the CPU fan speed accordng to the actual CPU temperature. ⷠFan cooler set wth 3 or 4 pns power connector are both avalable for CPUFAN. Ths connector allows you to connect the front panel audo and s complant wth Intel® Front Panel I/O Connectvty Desgn Gude. These connectors are for electrcal connecton to the front panel swtches and LEDs. There s a CMOS RAM onboard that has a power supply from an external battery to keep the data of system configuraton.

You can use them to change FSB clock at any tme under the operatng system. ths method does not need to nstall software or reboot. Please follow the steps below to ncrease or decrease the FSB clock. In order to ncrease the success rate, you should set the voltage n BIOS properly. ⷠAfter each of the adjustments, ths feature should be shut down. otherwse , t would affect the system performance. [. . . ] OC Step Ths tem s used to set how many steps for FSB colck overclockng. OC Step Count Tmer Ths tem s used to set the buffer tme for every step. CPU Core Control Ths tem allows you to select the number of actve processor cores. oC Gene Lte Settng ths tem to [Enabled] allows the system to detect the maxmum FSB clock and to overclock automatcally.
