[. . . ] Never pour any liquid into the opening that could damage or cause electrical shock. If any of the following situations arises, get the equipment checked by a service personnel: - The power cord or plug is damaged. - The equipment does not work well or you can not get it work according to User - The equipment has dropped and damaged. Do not leave this equipment in an environment unconditioned, storage temperature above 60° C (140°F), it may damage the equipment. [. . . ] (For the latest information about CPU, please visit our Web site at http://www. If CPU Clock Core/Bus ratio then CPU core speed = = = = = 133MHz 23 Host Clock x Core/Bus ratio 133MHz x 23 Overheating Overheating will seriously damage the CPU and system, always make sure the cooling fan can work properly to protect the CPU from overheating. Replacing the CPU While replacing the CPU, always turn off the ATX power supply or unplug the power supply's power cord from grounded outlet first to ensure the safety of CPU. Please turn off the power and unplug the power cord before installing the CPU. If the CPU is correctly installed, the pins should be completely embedded into the socket and can not be seen. Please note that any violation of the correct installation procedures may cause permanent damages to your mainboard. As the CPU is likely to move while the lever is being closed, always close the lever with your fingers pressing tightly on top of the CPU to make sure the CPU is properly and completely embedded into the socket. As processor technology pushes to faster speeds and higher performance, thermal management becomes increasingly important. To dissipate heat, you need to attach the CPU cooling fan and heatsink on top of the CPU. Press down the fan until its four clips get wedged in the holes of the retention mechanism. Connect the fan power cable from the mounted fan to the 3-pin fan power connector on the board. If you do not want to connect to the front audio header, pins 5 & 6, 9 & 10 have to be jumpered in order to have signal output directed to the rear Otherwise, the Line-Out connector on the back panel will not function. There is a CMOS RAM on board that has a power supply from external battery to keep the system configuration data. With the CMOS RAM, the system can automatically boot OS every time it is turned on. If you want to clear the system configuration, use the JBAT1 (Clear CMOS Jumper) to clear data. The PCI slots allow you to insert the expansion cards to meet your needs. When adding or removing expansion cards, make sure that you unplug the power supply first. Read the documentation for the expansion card to make any necessary hardware or software settings for the expansion card, such as jumpers, switches or BIOS configuration. The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines over which devices can send interrupt signals to the microprocessor. When the message below appears on the screen, press <DEL> key to enter Setup. DEL: Setup If the message disappears before you respond and you still wish to enter Setup, restart the system by turning it OFF and On or pressing the RESET button. Advanced BIOS Features Use this menu to setup the items of special enhanced features. [. . . ] Current FSB Frequency It shows the current clock frequency of the front side bus. (read only) Adjust CPU Ratio This setting controls the multiplier that is used to determine the internal clock speed of the processor relative to the external or motherboard clock speed. adjust CPU/AGP/PCI Frequency This setting allows you to select the clock frequency of CPU/AGP/PCI. AGP Voltage AGP voltage is adjustable in the field, allowing you to increase the performance of your AGP display card when overclocking, but the stability may be affected. [. . . ]
