User manual MSI G52-76231XJ 4.1

[. . . ] Notice 1 The changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. Power cord, if any, must be used in order to comply with the emission limits. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation The material in this document is the intellectual property of MICRO-STAR INTERNATIONAL. [. . . ] If you'd like to use the ATX power supply, please plug your power supply along with pin 1 & pin 13 (refer to the image at the right hand). There is also a foolproof design on pin 11, 12, 23 & 24 to avoid wrong installation. This 12V power connector is used to provide power to the CPU. These two connectors connect to the ATX power supply and have to work together to ensure stable operation of the mainboard. For ATX 12V power connection, it should be greater than 18A. NForce chipset is very sensitive to ESD (Electrostatic Discharge), therefore this issue mostly happens while the users intensively swap memory modules under S5 (power-off) states, and the power code is plugged while installing modules. Due to several pins are very sensitive to ESD, so this kind of memory-replacement actions might cause system chipset unable to boot. Please follow the following solution to avoid this situation. Unplug the AC power cable (shown in figure 1) or unplug the ATX1 & JPW1 power connectors (shown in figure 2 & figure 3) before the 1st installation or during system upgrade procedure. Figure 1: Unplug the AC power cable Figure 2: Unplug the ATX1 power connector Figure 3: Unplug the JPW1 power connector The back panel provides the following connectors: Parallel Mouse LAN LAN (Optional) (Optional) L-In RS-Out 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. Each Serial ATA connector can connect to 1 hard disk device. (Optional) 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.

Green Description System Power ON The D-LED will hang here if the processor is damaged or not installed properly. Memory Detection Test Testing onboard memory size. The D-LED will hang if the memory module is damaged or not installed properly. Testing Base and Extended Memory Testing base memory from 240K to 640K and extended memory above 1MB using various patterns. The motherboard provides the following button for you to set the computer's function. This section will explain how to change your motherboard's function through the use of button. [. . . ] When the motherboard detects CPU is running programs, it will speed up CPU automatically to make the program run smoothly and faster. When the CPU is temporarily suspending or staying in the low load balance, it will restore the default settings instead. Usually the Dynamic Overclocking Technology will be powered only when users' PC need to run huge amount of data like 3D games or the video process, and the CPU frequency need to be boosted up to enhance the overall performance. Even though the Dynamic Overclocking Technology is more stable than manual overclocking, basically, it is still risky. [. . . ]
