BIOS Setup start of a column-read command. It allows I/O gating to overdrive sense amplifiers before read command starts. DRAM TRRD W hen the Configuration DRAM Timing by SPD sets to [Disabled], the field is adjustable. Specifies the active-to-active delay of different banks. Time interval between a read and a precharge command. DRAM TRTP W hen the Configuration DRAM Timing by SPD sets to [Disabled], the field is adjustable. Time interval between a read and a precharge command. FSB/Memory Ratio This item will allow you to adjust the FSB/Ratio of the memory. Adjusted DDR M emory Frequency It shows the adjusted DDR Memory frequency. Read-only. PCIEx4 Speed Controller This item will allow you to select the PCIEx4 speed. Adjust PCIE Frequency This field allows you to select the PCIE frequency (in MHz). Auto Disable DIMM/PCI Frequency W hen set to [Enabled], the system will remove (turn off) clocks from empty DIMM and PCI slots to minimize the electromagnetic interference (EMI). CPU Voltage / Momory Voltage / VTT FSB Voltage / NB Voltage / SB I/O Power / SB Core Power These items dispaly the power status of CPU, Memory, FSB and chipset. Read-only. Spread Spectrum W hen 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. If you do not have any EMI problem, leave the setting at Disabled for optimal system stability and performance. But if you are plagued by EMI, set to Enabled for EMI reduction. Remember to disable Spread Spectrum if you are overclocking because even a slight jitter can introduce a temporary boost in clock speed which may just cause your overclocked processor to lock up. 3-23
