manual abstract
o- PCI Express Frequency (Mhz) Allows you to manually set the PCIe clock frequency. The adjustable range is from 90 MHz to 150 MHz. Auto sets the PCIe clock frequency to standard 100 MHz. (Default: Auto) ^ C.I.A.2 CPU Intelligent Accelerator 2 (C.I.A.2) is designed to automatically adjust CPU computing power to maximize system performance. C.I.A.2 allows your system bus to be changed dynamically based on CPU loading through the use of 5 preset states. Note: System stability varies, depending on your system hardware components. ►► Disabled Disables the use of C.I.A.2. (Default) ►► Cruise Increases CPU frequency by 5% or 7% depending on CPU loading. ►► Sports Increases CPU frequency by 7% or 9% depending on CPU loading. ►► Racing Increases CPU frequency by 9% or 11% depending on CPU loading. to Turbo Increases CPU frequency by 15% or 17% depending on CPU loading. to Full Thrust Increases CPU frequency by 17% or 19% depending on CPU loading. Warning: Before using C.I.A.2, please first verify the overclocking capability of your CPU. As stability is highly dependent on system components, when system instability occurs after overclocking, lower the overclocking ratio. (Note) This item appears only if you install a CPU that supports this feature. - 47 - BIOS Setup Performance Enhance Allows the system to operate at three different performance levels. to Standard Lets the system operate at its basic performance level. to Turbo Lets the system operate at its good performance level. (Default) to Extreme Lets the system operate at its best performance level. System Memory Multiplier Allows you to set the system memory multiplier. Options are dependent on CPU FSB. Auto sets memory multiplier according to memory SPD data. (Default: Auto) v Memory Frequency (Mhz) The first memory frequency value is the normal operating frequency of the memory being used; the second is the memory frequency that is automatically adjusted according to the CPU Host Frequency (Mhz) and System Memory Multiplier settings. v DRAM Timing Selectable (SPD) Manual allows all DRAM Timing items below to be configurable. Options are: Auto (default), Manual. ******** Standard Timing Control ******** o" CAS Latency Time Options are: Auto (default), 3—6. DRAM RAS# to CAS# Delay Options are: Auto (default), 1~15. v DRAM RAS# Precharge Options are: Auto (default), 1~15. Precharge delay (tRAS) Options are: Auto (default), 1 ~63. ******** Advanced Timing Control ******** ACT to ACT Delay (tRRD) Options are: Auto (default), 1~15. v Rank Write to READ Delay Options are: Auto (default), 1—31. cr Write To Precharge Delay Options are: Auto (default), 1—31. cr Refresh to ACT Delay Options are: Auto (default), 0—255. o" Read to Precharge Delay Options are: Auto (default), 1—15. o- Static tRead Value Options are: Auto (default), 1—31. Static tRead Phase Adjust Options are: Auto (default), 1—31. GA-EP35-DS3L/S3L Motherboard - 48 - ******** System Voltage Optimized ******** System Voltage Control Determines whether to manually set the system voltages. Auto lets BIOS automatically set the system voltages as required. Manual allows all voltage control items below to be configurable. (Default: Manual) o" DDR2 OverVoltage Control Allows you to set memory voltage. ►► Normal Supplies the memory voltage as required. (Default) ►► +0.1V ~ +0.7V Increases memory voltage by 0.1V to 0.7V at 0.1V increment. Note: Increasing memory voltage may result in damage to the memory. o" PCI-E OverVoltage Control Allows you to set PCIe voltage. ►► Normal Supplies the PCIe bus voltage as required. (Default) ►► +0.1V ~ +0.3V Increases PCIe bus voltage by 0.1V to 0.3V at 0.1V increment. o" FSB OverVoltage Control Allows you to set the Front Side Bus voltage. ►► Normal Supplies the FSB voltage as required. (Default) ►► +0.1V ~ +0.3V Increases FSB voltage by 0.1V to 0.3V at 0.1V increment. o" (G)MCH OverVoltage Control Allows you to set the North Bridge voltage. ►► Normal Supplies the North Bridge voltage as required. (Default) ►► +0.1V ~ +0.3V Increases North Bridge voltage by 0.1V to 0.3V at 0.1V increment. CPU Voltage Control Allows you to set the CPU voltage. Normal sets the CPU voltage as required. The adjustable range is dependent on the CPU being installed. (Default: Normal) Note: Increasing CPU voltage may result in damage to your CPU or reduce the useful life of the CPU. o" Normal CPU Vcore Displays the normal operating voltage of your CPU. - 49 - BIOS Setup 2-10 Load Fail-Safe Defaults Press
