English Sports Set C.I.A.2 to Sports. (Automatically increase CPU frequency(7%,9%) by CPU loading. Racing Set C.I.A.2 to Racing. (Automatically increase CPU frequency(9%,11%) by CPU loading. Turbo Set C.I.A.2 to Turbo. (Automatically increase CPU frequency(15%,17%) by CPU loading. Full Thrust Set C.I.A.2 to Full Thrust. (Automatically increase CPU frequency(17%,19%) by CPU loading. Warning: Stability is highly dependent on system components. CPU Host Clock Control Please note that if your system is overclocked and cannot restart, please wait 20secs. for automatic system restart or clear the CMOS setup data and perform a safe restart. Disabled Disable CPU Host Clock Control. (Default value) Enabled Enable CPU Host Clock Control. CPU Host Frequency (Mhz) This item will be available when "CPU Host Clock Control" is set to Enabled. 100MHz ~ 600MHz Set CPU Host Clock from 100MHz to 600MHz. If you use FSB800 Pentium 4 processor, please set "CPU Host Frequency" to 200MHz. Incorrect using it may cause your system broken. For power End-User use only! PCI Experss Frequency (Mhz) Auto Set PCI Express frequency automatically. (Default value) 100~130 Set PCI Express frequency from 100MHz to 130MHz. 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 Memory frequency by DRAM SPD data. (Default value) for FSB(Front Side Bus) frequency=800MHz, 1.66 Memory Frequency = Host clock X 1.66. 2.00 Memory Frequency = Host clock X 2. 2.66 Memory Frequency = Host clock X 2.66. 3.00 (Note) Memory Frequency = Host clock X 3. Auto Set Memory frequency by DRAM SPD data. (Default value) Memory Frequency (Mhz) The values depend on "Memory Frequency For" item. DIMM OverVoltage Control Please note that by overclocking your system through the increase of the DIMM voltage, damage to the memory may occur. Normal Set DIMM OverVoltage Control to Normal. (Default value) +0.1V Set DIMM OverVoltage Control to +0.1V. +0.2V Set DIMM OverVoltage Control to +0.2V. (Note) To use a DDRII 600 memory module on the motherboard, you must install an 800MHz FSB processor and set Memory Frequency For to 3.00. - 47 - BIOS Setup
