English
CPU Host Clock Control
Please note that if your system is overclocked and cannot restart, please wait 20secs.
for a utomatic s y stem res tart or c lear the C MOS setup data and perform a safe res tart.
Disabled
Disable CPU Host Clock C ontrol. (Default v alue)
Enabled
Enable CPU Host Clock Control.
CPU Host Frequency (Mhz)
100MHz ~ 355MHz
Set CPU Host Clock from 100MHz to 355MHz.
If y ou use FSB533 Pentium 4 processor, please set "CPU Clock" to 133MHz.If y ou use FSB800
Pentium 4 processor, please set "CPU Clock" to 200MHz.
Incorrect using it may cause y our sy stem broken. For pow er End-User use only !
Memory Frequency For
Wrong frequency may make system can't boot, clear CMOS to overcome wrong frequency issue.
for FSB(Front Side Bus) frequency=533MHz,
2.5
Memory Frequency = Host clock X 2.5
3
Memory Frequency = Host clock X 3.
4
Memory Frequency = Host clock X 4.
Auto
Set M emory frequency by DRAM SPD data. (Default v alue)
for FSB(Front Side Bus) frequency=800MHz,
1.66
Memory Frequency = Host clock X 1.66.
2.0
Memory Frequency = Host clock X 2.0.
2.66
Memory Frequency = Host clock X 2.66.
Auto
Set M emory frequency by DRAM SPD data. (Default v alue)
Memory Frequency (Mhz)
The v alues depend on "Mem ory Frequency For" item.
DIMM OverVoltage Control
Please note that by ov erclocking y our sy stem through the increase of the DIMM v oltage, damage to the
memory may occur.
Normal
Set DIMM Ov erVoltage Control to Normal. (Default v alue)
+0.1V
Set DIMM OverVoltage Control to +0.1V.
+0.2V
Set DIMM OverVoltage Control to +0.2V.
+0.3V
Set DIMM OverVoltage Control to +0.3V.
Incorrect using it may cause your system broken. For power End-User use only!
PCI-E OverVoltage Control
Normal
Set PCI-E Ov erVoltrage C ontrol to Normal. (Default v alue)
+0.1V
Set PCI-E OverVoltrage Control to +0.1V.
+0.2V
Set PCI-E OverVoltrage Control +0.2V.
+0.3V
Set PCI-E OverVoltrage Control +0.3V.
Incorrect using it may cause your system broken. For power End-User use only!
CPU Voltage Control
Supports adjustable CPU Vcore from 0.8375V to 1.6000V. (Default v alue: Normal)
Normal CPU Vcore
