User manual MSI G52-M6570E8 VERSION 1.X

[. . . ] This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case the user will be required to correct the interference at his own expense. [. . . ] These two connectors connect to the ATX power supply and have to work together to ensure stable operation of the mainboard. The back panel provides the following connectors: You can plug a PS/2® mouse/keyboard directly into this connector. You can attach a serial mouse or other serial devices directly to the connector. This mainboard may provide two different combinations of Audio Port Connectors: TYPE I and TYPE II. Both TYPE I and TYPE II integrate three audio jacks for 2-channel mode stereo speaker output: Line In is used for external CD player, Tape player, or other audio devices. However, TYPE II also integrates an advanced audio application which is provided by Realtek ALC655 to offer support for 6-channel audio operation and can turn rear audio connectors from 2-channel to 4-/6-channel audio. For advanced audio application, Realtek ALC655 audio chip is provided to offer support for 6-channel audio operation and can turn rear audio connectors from 2-channel to 4-/6-channel audio. The CPU_FAN1 (processor fan), S_FAN1 (system fan 1), S_FAN2 (system fan 2) and NB_FAN1 (NorthBridge Chipset fan) support system cooling fan with +12V. When connecting the wire to the connectors, always take 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. You can connect up to four hard disk drives, CD-ROM, 120MB Floppy (reserved for future BIOS) and other devices. IDE2 IDE1 IDE1 (Primary IDE Connector) The first hard drive should always be connected to IDE1. You must configure second hard drive to Slave mode by setting the jumper accordingly. If you install two hard disks on cable, you must configure the second drive to Slave mode by setting its jumper. The Southbridge of this mainboard is nForce2 RAID MCP which supports two serial ATA connectors SATA1 and SATA2. Take out the dust cover and connect to the hard disk devices Please do not fold the serial ATA cable in a 90-degree angle, which will cause the loss of data during the transmission. The mainboard provides two front panel connectors for electrical connection to the front panel switches and LEDs.

The JAUD1 front panel audio connector allows you to connect to the front panel audio and is compliant with Intel® Front Panel I/O Connectivity Design Guide. The orange PCI slot (PCI5) also works as a communication slot, which allows you to insert the communication card. 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. This chapter provides information on the BIOS Setup program and allows you to configure the system for optimum use. [. . . ] Even though the Dynamic Overclocking Technology is more stable than manual overclocking, basically, it is still risky. We suggest user to make sure that your CPU can afford to overclock regularly first. If you find the PC appears to be unstable or reboot incidentally, it's better to disable the Dynamic Overclocking or to lower the level of overclocking options. By the way, if you need to conduct overclocking manually, you also need to disable the Dynamic Overclocking first. [. . . ]
