Resumen del manual
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. ►►Turbo Increases CPU frequency by 15% or 17% depending on CPU loading. ►► 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. >>>>> Advanced Clock Control o- Advanced Clock Control - 39 - BIOS Setup c CPU Clock Drive Allows you to adjust the amplitude of the CPU and North Bridge clock. Options are: 700mV, 800mV (default), 900mV, 1000mV. o- PCI Express Clock Drive Allows you to adjust the amplitude of the PCI Express and North Bridge clock. Options are: 700mV, 800mV, 900mV (default), 1000mV. o- CPU Clock Skew Allows you to set the CPU clock prior to the North Bridge clock. Options are: 0ps~750ps. (Default: 0ps) o- MCH Clock Skew Allows you to set the North Bridge clock prior to the CPU clock. Options are: 0ps~750ps. (Default: 0ps) ******** DRAM Performance Control ******** o- Performance Enhance Allows the system to operate at three different performance levels. * Standard Lets the system operate at its basic performance level. ►►Turbo Lets the system operate at its good performance level. (Default) ►► Extreme Lets the system operate at its best performance level. o- Extreme Memory Profile (X.M.P.) |No,e| Allows the BIOS to read the SPD data on XMP memory module(s) to enhance memory performance when enabled. ►► Auto Lets the BIOS automatically detect whether a XMP memory module is installed. If a XMP memory module is installed, this function will be enabled. (Default) ►► Profile2 Uses Profile 2 settings. ►► Disabled Disables this function. o- (G)MCH Frequency Latch Allows you to fix the chipset frequency at system bootup. Options for adjusting memory multiplier below may differ according to the fixed frequency. Options are: Auto (default), 200MHz, 266MHz, 333MHz, 400MHz. o- System Memory Multiplier (SPD) Allows you to set the system memory multiplier. Options are dependent on CPU FSB and the (G)MCH Frequency Latch settings. Auto sets memory multiplier according to memory SPD data. (Default: Auto) o- 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. o- DRAM Timing Selectable (SPD) Manual allows all DRAM timing control items below to be configurable. Options are: Auto (default), Manual. (Note) This item appears only if you install a memory module that supports this feature. GA-EP45-UD3 Motherboard - 40 - >>>>> Standard Timing Control c CAS Latency Time Options are: Auto (default), 3~7. o- tRCD Options are: Auto (default), 1~15. o- tRP Options are: Auto (default), 1~15. o- tRAS Options are: Auto (default), 1~63. >>>>> Advanced Timing Control o- Advanced Timing Control >>>>> Advanced Timing Control O- tRRD Options are: Auto (default), 1~15. o- tWTR Options are: Auto (default), 1~31. o- tWR Options are: Auto (default), 1~31. o- tRFC Options are: Auto (default), 1~255. o- tRTP Options are: Auto (default), 1~15. o- Command Rate(CMD) Options are: Auto (default), 1~3. - 41 - BIOS Setup >>>>> Channel A/B a- Channel A/B Timing Settings CMOS Setup Utility-Copyright (C) 1984-2009 Award Software Channel A/B Timing Settings x Static tRead Value x tRD Phase0 Adjustment x tRD Phase1 Adjustment x tRD Phase2 Adjustment x tRD Phase3 Adjustment x Trd2rd(Different Rank) x Twr2wr(Different Rank) x Twr2rd(Different Rank) x Trd2wr(Same/Diff Rank) x DIMM1 Clock Skew Control x DIMM2 Clock Skew Control x DDR Write Training : Move Enter: Select F5: Previous Values Item Help Menu Level ►►► +/-/PU/PD: Value F6: Fail-Safe Defaults ESC: Exit F1: General Help F7: Optimized Defaults Static tRead Value Options are: Auto (default), 1~15. tRD PhaseO Adjustment Options are: Auto (default), 0-Normal, 1-Advanced. tRD Phasel Adjustment Options are: Auto (default), 0-Normal, 1-Advanced. tRD Phase2 Adjustment Options are: Auto (default), 0-Normal, 1-Advanced. tRD Phase3 Adjustment Options are: Auto (default), 0-Normal, 1-Advanced.
