User manual MSI G52-75221XI V5.0

[. . . ] Keep this User Manual for future reference. Lay this equipment on a reliable flat surface before setting it up. 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. [. . . ] Wrong installation will cause the damage of your CPU & mainboard. The CPU socket has a plastic cap on it to protect the contact from damage. Before you have installed the CPU, always cover it to protect the socket pin. Lift the load lever up and open the load plate. After confirming the CPU direction for correct mating, put down the CPU in the socket housing frame. If not, take out the CPU with pure vertical motion and reinstall. Press down the load lever lightly onto the load plate, and then secure the lever with the hook under retention tab. Push down the cooler until its four clips get wedged into the holes of the mainboard. Then rotate the locking switch (refer to the correct direction marked on it) to lock the hooks. Turn over the mainboard to confirm that the clip-ends are correctly inserted. Whenever CPU is not installed, always protect your CPU socket pin with the plastic cap covered to avoid damaging. Each connector can connect to one Serial ATA device. Important: Please do not fold the Serial ATA cable into 90-degree angle. Otherwise, data loss may occur during transmission. 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 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. These connectors are for electrical connection to the front panel switches and LEDs. The system will record this status and show a warning message on the screen. [. . . ] Save & Exit Setup Save changes to CMOS and exit setup. Advance DRAM Configuration > DRAM CAS# Latency The field controls the CAS latency, which determines the timing delay before DRAM starts a read command after receiving it. FSB/Memory Ratio This setting controls the ratio of CPU FSB Clock & Memory Frequency to enable the CPU & memory to run at different frequency combinations. 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. [. . . ]
