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.Settings are: [Auto] The output speed depends on the device installed on PCIEx4 slot. [4X] The output speed keeps on 4X. In this mode, PCI_E2 and PCI_E3 are not able to function. [2X] The output speed keeps on 2X. In this mode, you may use PCI_E2, PCI_E3 and PCI_E4 simultaneously, please note that the output speed on PCI_E4 in only with 2X. 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

BIOS Setup
start of a column-read command. It allows I/O gating to overdrive sense amplifiers
before read command starts.
DRAM TRRD
When 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
When 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 Memory Frequency
It shows the adjusted DDR Memory frequency. Read-only.
