Auto Detect PCI Clk
When enabled the mainboard automatically disables the clock source for a PCI slot
which does not have a module in it, reducing EMI (ElectroMagnetic Interference).
Options: Enabled, Disabled.
Spread Spectrum
If you enable spread spectrum, it can significantly reduce the EMI (ElectroMagnetic
Interference) generated by the system.
Options: Disabled, -0.35%, -0.50%, -0.75%, -1.00%.
CPU Clock
Enables you to increment the CPU’s clock generator at 1 MHz step. This works
together with CPU Clock Ratio (above) to set the CPU operating frequency.
CPU Clock Generator x CPU Clock Ratio = CPU Frequency
For example, if you have a processor that is rated at 2.4GHz and the clock generator
is 200MHz, then 200MHz x 12 = 2.4GHz
Key in the DEC (decimal) number for the CPU Clock Ratio.
Note: Overclocking failure will cause no display on the monitor. To overcome
this switch off the power supply and switch on again. Restart the
system, press and hold
<
Insert>
key. This will revert the BIOS to default
or initial setting.
CPU Vcore Voltage
This item allows you to set the CPU Vcore voltage.
Options: Default, 1.400V to 1.850V in 0.025V increment and 1.900V to 2.000V in 0.050V
increment. We recommend that you leave this at the default value.
DIMM Voltage
This item allows you to adjust the DIMM slot voltage.
Options: +0.00V to +0.70V in 0.10V increments. We recommend that you leave this at
the default value.
