Spread Spectrum Modulated
Disabled Disable Spread Spectrum Modulated.
Enabled Enable Spread Spectrum Modulated.(Default value)
CPU Host Clock Control
Note: If system hangs up before enter CMOS setup utility, wait for 20 sec for times out reboot .
When time out occur, system will reset and run at CPU default Host clock at next boot.
Disable Disable CPU Host Clock Control.(Default value)
Enable Enable CPU Host Clock Control.
CPU Host Frequency (MHz)
To change these settings, you must first select Enable under "CPU Host Clock Control".
100-132 If your CPU host frquency is 100MHz, you can choose the 100MHz-132MHz
range to adjust CPU host frequency.
133-165 If your CPU host frquency is 133MHz, you can choose the 133MHz-165MHz
range to adjust CPU host frequency.
166-250 If your CPU host frquency is 166MHz, you can choose the 166MHz-250MHz
range to adjust CPU host frequency.
200-254 If your CPU host frquency is 200MHz, you can choose the 200MHz-254MHz
range to adjust CPU host frequency.
PCI/AGP Frequency (MHz)
The values depend on CPU Host Frequency(Mhz) .
DRAM Clock
By SPD BIOS will automatically setup the DRAM clock by DRAM SPD data. (Default
Value).
133 If you use DDR266 DRAM module, please set "DRAM Clock(MHz)" to "133".
166 If you use DDR333 DRAM module, please set "DRAM Clock(MHz)" to "166".
200 If you use DDR400 DRAM module, please set "DRAM Clock(MHz)" to "200".
CPU Voltage Control
Increase CPU voltage may get stable for Over_Clock. But it may damage to CPU when enable
this feature.
Supports adjustable CPU Vcore from 1.100V to 2.050V.
(Default value: Normal)
Normal CPU Vcore
Display your CPU Vcore voltage.
AGP Voltage Control
Increase AGP voltage may get stable for over-clock. But it may damage to AGP card if improper
setting this feature.
Auto Supply AGP voltage as AGP required(1.5V). (Default value)
+0.1V Increase AGP voltage +0.1V.
+0.2V Increase AGP voltage +0.2V.
+0.3V Increase AGP voltage +0.3V.
DDR Voltage Control
Increase DDR voltage may get stable for over-clock. But it may damage to memory module if
improper setting this feature.
Auto Supply DDR voltage as memory module required(2.5V). (Default value)
+0.1V Increase DDR voltage +0.1V.
+0.2V Increase DDR voltage +0.2V.
