User manual MSI K8N NEO3

[. . . ] 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. [. . . ] This connector allows you to connect an ATX 24-pin power supply. 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. Then push down the power supply firmly into the connector. You may use the 20-pin ATX power supply as you like. If you'd 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). 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. ATX 12V power connection should be greater than 18A. NVIDIA chipset is very sensitive to ESD (Electrostatic Discharge), therefore this issue mostly happens while 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 chipset system unable to boot. Please follow the following solution to avoid this situation. Unplug the AC power cable (shown in figure 1) or unplug the JW R1 & JPW 1 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 JWR1 power connector Figure 3: Unplug the JPW 1 power connector Mainboard photos shown in this section are for demonstration only. The appearance of your mainboard may vary depending on the model you purchase. The system will record this status and show a warning message on the screen. To clear the warning, you must enter the BIOS utility and clear the record. Each supports 1st generation serial ATA data rates of 150MB/s and is fully compliant with Serial ATA 1. Each Serial ATA connector can connect to 1 hard disk device. Take out the dust cover and connect to the hard disk devices 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. [. . . ] We suggest that users should make sure that the CPU can afford to overclocking 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. When overclocking, it is NOT recommended to use SATA devices. [. . . ]
