PCI Health Status Option On mainboards which support hardware monitoring, this item lets you monitor the parameters for critical voltages, critical temperatures, and fan speeds. If this option is active on your system, we recommend that you accept the default values. Frequency Control Option This item allows you to set the clock speed and system bus for your system. The clock speed and system bus are determined by the kind of processor you have installed in your system. Auto Detect DIMM/PCI Clk Default: Disabled When this item is enabled, BIOS will disabled the clock signal of free DIMM and PCI slots. CPU Internal Core Speed Default: Auto Use this item to automatically set up the mainboard for the kind of processor that you have installed. Set this item to the rated internal clock speed of the installed processor. If you set this to Manual, two new items appear: CPU/DIMM/PCI Clock and CPU Clock Ratio. Spread Spectrum Default: Disabled If you enable spread spectrum, it can significantly reduce the EMI (Electro-Magnetic Interference) generated by the system. CPU/DIMM/PCI Clock CPU Clock ratio These items appear if you have set the CPU Internal Core Speed to Manual. Use the CPU/DIMM/PCI Clock to set the system bus frequency for the installed processor (usually 133 MHz,100 MHz or 66 MHz). Then use CPU Clock Ratio to set a multiple. The multiple times the system bus must equal the core speed of the installed processor e.g. 3.5 (multiple) x 100 MHz (system bus) = 350 MHz (installed processor clock speed). 59
