[. . . ] 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. [. . . ] We do not guarantee the damages or risks caused by inadequate operation or beyond product specifications. When you are installing the CPU, make sure the CPU has a cooler attached on the top to prevent overheating. If you do not have the cooler, contact your dealer to purchase and install them before turning on the computer. Meanwhile, do not forget to apply some silicon heat transfer compound on CPU before installing the cooler for better heat dispersion. Then press down the other end of the clip to fasten the cooling set on the top of the retention mechanism. Confirm if your CPU cooler is firmly installed before turning on your system. The mainboard provides two 240-pin DIMM slots for unbuffered DDR II 533 / 667 / 800 SDRAM (DDR II 800 is only for Athlon 64 X2). You can install either single- or double-sided modules to meet your own needs. Then push it in until the golden finger on the memory module is deeply inserted in the socket. Before inserting the power supply connector, always make sure that all components are installed properly to ensure that no damage will be caused. 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'd like to use the 20-pin ATX power supply, please plug your power supply along with pin 1 & pin 13. There is also a foolproof design on pin 11, 12, 23 & 24 to avoid wrong installation. You can connect up to two hard disk drives, CD-ROM, 120MB Floppy and other devices. You must configure second hard drive to Slave mode by setting the jumper accordingly. If you install two hard disks on one cable, you must configure the second drive to Slave mode by setting its jumper. Please do not fold the serial ATA cable in a 90-degree angle, which will cause the loss of data during transmission. The 4-pin CPUFAN1 (processor fan) and 3-pin SYSFAN1 (system 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. The mainboard provides a front panel connector for electrical connection to the front panel switches and LEDs. The 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.
