User manual MSI G52-72671XJ

[. . . ] Our products are under continual improvement and we reserve the right to make changes without notice. NVIDIA , the NVIDIA logo, DualNet, and nForce are registered trademarks or trademarks of ® NVIDIA Corporation in the United States and/or other countries. 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 connecting the equipment to the power inlet. [. . . ] The appearance of your mainboard may vary depending on the model you purchase. According to the Intel North Bridge 945GC chipset spec, this board supports CPU of FSB 800MHz at maximum by default. However, you may let your board running at FSB 1066MHz (Core 2 Duo CPUs) by overclocking and adjusting the CPU FSB frequency in the BIOS : Enter BIOS setup menu and go to [Frequency/ Voltage Control]à[Adjust CPU FSB Frequency]. Please be noted that this is over-spec, and this overclocking behavior is not recommended and not guaranteed. 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. You can barely see the golden finger if the memory module is properly inserted in the DIMM slot. Important: DDR2 memory modules are not interchangeable with DDR and the DDR2 standard is not backwards compatible. To enable successful system boot-up, always insert the memory modules into the DIMM1 first. 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 like to use the 20-pin ATX power supply, please plug your power supply along with pin 1 & pin 13 (refer to the image at the right hand). Make sure that all the connectors are connected to proper ATX power supplies to ensure stable operation of the mainboard. 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 90-degree angle. 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 on-board, you must use a specially designed fan with speed sensor to take advantage of the CPU fan control. 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. This connector is used to connect S/PDIF (Sony & Philips Digital Interconnect Format) interface for digital audio transmission. This connector allows you to connect the front ® panel audio and is compliant with Intel I/O Connectivity Design Guide. [. . . ] Adjust PCI Frequency This item allows you to select the PCI clock frequency (in MHz) and overclock by adjusting the PCI clock to a higher frequency. Adjust PCIE Frequency This item allows you to select the PCI Express clock frequency (in MHz) and overclock by adjusting the PCI Express clock to a higher frequency. Any changes made to this setting may cause a stability issue, so changing the voltage for long-term purpose is NOT recommended. Spread Spectrum When the motherboard's clock generator pulses, the extreme values (spikes) of the pulses create EMI (Electromagnetic Interference). [. . . ]
