[. . . ] Alternatively, please try the following help resources for further guidance. Visit the MSI website for FAQ, technical guide, BIOS updates, driver updates, and other information: http://www. The openings on the enclosure are for air convection hence protects the equipment from overheating. Make sure the voltage of the power source and adjust properly 110/220V before Place the power cord such a way that people can not step on it. [. . . ] The following illustrations explain the population rules for Dual-Channel mode. DDR3 memory modules are not interchangeable with DDR2 and the DDR3 standard is not backwards compatible. â· In Dual-Channel mode, make sure that you install memory modules of the same type and density in different channel DIMM slots. â· To enable successful system boot-up, always insert the memory modules into the DIMM1 first. The memory module has only one notch on the center and will only fit in the right orientation. Then push it in until the golden finger on the memory module is deeply inserted in the DIMM slot. The plastic clip at each side of the DIMM slot will automatically close when the memory module is properly seated. Manually check if the memory module has been locked in place by the DIMM slot clips at the sides. You can barely see the golden finger if the memory module is properly inserted in the DIMM slot. To connect the ATX 24-pin power supply, make sure the plug of the power supply is inserted in the proper orientation and the pins are aligned. If you'd like to use the 20-pin ATX power supply, please plug your power supply along with pin 1 & pin 13. The PCI slot supports LAN card, SCSI card, USB card, and other add-on cards that comply with PCI specifications. When adding or removing expansion cards, make sure that you unplug the power supply first. Meanwhile, read the documentation for the expansion card to configure 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. These APS (Active Phase Switching) LED indicates the current CPU power phase mode. This chapter provides basic information on the BIOS Setup program and allows you to configure the system for optimum use. You may need to run the Setup program when: An error message appears on the screen during the system booting up, and requests you to run BIOS SETUP. The items under each BIOS category described in this chapter are under continuous update for better system performance. Therefore, the description may be slightly different from the latest BIOS and should be held for reference only. â· Upon boot-up, the 1st line appearing after the memory count is the BIOS version. When the message below appears on the screen, press <DEL> key to enter Setup. [. . . ] start OC Stepping From (MHz) This item is used to set the initial base clock. The system will boot with the initial base clock, and start to overclock from initial base clock to set base clock that you set in "Adjust CPU Base Frequency (MHz)" step by step. OC Step This item is used to set how many steps for base colck overclocking. OC Step Count Timer This item is used to set the buffer time for every step. [. . . ]
