N n n n n n n n n n n Always read the safety instructions carefully. [. . . ] Mainboard photos shown in this section are for demonstration of the CPU/cooler installation only. The appearance of your mainboard may vary depending on the model you purchase. According to the Intel North Bridge 945GC chipset spec, this board supports CPU of FSB 800MHz at maximum by default. However, you may let your board running at FSB 1066MHz (Core 2 Duo CPUs) by overclocking and adjusting the CPU FSB frequency in the BIOS : Enter BIOS setup menu and go to [Frequency/ Voltage Control]à[Adjust CPU FSB Frequency]. there you can adjust the value to [266] for the Core 2 Duo CPUs. Please be noted that this is over-spec, and this overclocking behavior is not recommended and not guaranteed. The memory module has only one notch on the center and will only fit in the right orientation. Insert the memory module vertically into the DIMM slot. Then push it in until the golden finger on the memory module is deeply inserted in the DIMM slot. You can barely see the golden finger if the memory module is properly inserted in the DIMM slot. Important: DDR2 memory modules are not interchangeable with DDR and the DDR2 standard is not backwards compatible. You should always install DDR2 memory modules in the DDR2 DIMM slots. To enable successful system boot-up, always insert the memory modules into the DIMM1 first. 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 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). This 12V power connector is used to provide power to the CPU. Make sure that all the connectors are connected to proper ATX power supplies to ensure stable operation of the mainboard. This connector supports IDE hard disk drives, optical disk drives and other IDE devices. Important: If you install two IDE devices on the same cable, you must configure the drives to cable select mode or separately to master / slave mode by setting jumpers. [. . . ] Adjust PCIE Frequency This item allows you to select the PCI Express clock frequency (in MHz) and overclock by adjusting the PCI Express clock to a higher frequency. Any changes made to this setting may cause a stability issue, so changing the voltage for long-term purpose is NOT recommended. Spread Spectrum When the motherboard's clock generator pulses, the extreme values (spikes) of the pulses create EMI (Electromagnetic Interference). the Spread Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves.
