[. . . ] W hen a password has been set, you will be prompted to enter it every time you try to enter Setup. This prevents an unauthorized person from changing any part of your system configuration. 3-20 BIOS Setup Cell Menu Important Change these settings only if you are familiar with the chipset. Current CPU / DRAM Frequency These items show the current clocks of CPU and Memory speed. Multi-step OC Booster This item is used to avoid the BIOS might crash with overclocking. Mode 1 Slight OC during POST and then apply full OC when loading the OS Mode 2 Load the OS then apply the OC settings. 3-21 M S-7514 M ainboard D. O. T. (Dynamic Overclocking Technology) is an automatic overclocking function, included in the SONYTM 's newly developed Dual CoreCellTM Technology. It is designed to detect the load balance of CPU while running programs, and to adjust the best frequency automatically. W hen the mainboard detects system is running programs, it will speed up automatically to make the program run smoothly and faster. W hen the system is temporarily suspending or staying in the low load balance, it will restore the default settings instead. Usually the Dynamic Overclocking Technology will be powered only when users' PC need to run huge amount of data like 3D games or the video process, and the CPU and PCIE frequency need to be boosted up to enhance the overall performance. Important Even though the Dynamic Overclocking Technology is more stable than manual overclocking, basically, it is still risky. We suggest user to make sure that your CPU / memory modules can afford to overclocking regularly first. Specifies the active-to-active delay of different banks. 3-24 BIOS Setup TRTP W hen the Adcance M emory Setting sets to [Manual], the field is adjustable. CHA TRD/ TRD2RD/ TWR2WR/ TWR2RD/ /TWD2WR/ TRD Phase W hen the Adcance M emory Setting s ets to [Manual], these fields are adjustable. CHB TRD/ TRD2RD/ TWR2WR/ TWR2RD/ TRD2WR/ TRD Phase W hen the Adcance M emory Setting s ets to [Manual], these fields are adjustable. FSB/DRAM Ratio This item will allow you to adjust the ratio of FSB to memory. Adjusted DRAM Frequency (MHz) It shows the adjusted DDR Memory frequency. ClockGen Tuner Press <Enter> to enter the sub-menu. CPU Clock Drive/ PCI Express Clock Drive These items are used to select the CPU/ PCI Express clock amplitude. CPU CLK Skew/ M CH CLK Skew These items are used to select the CPU/ North Bridge chipset clock skew. Adjust PCI Frequency (MHz) This field allows you to select the PCI frequency (in MHz). Auto Disable DRAM /PCI Frequency W hen set to [Enabled], the system will remove (turn off) clocks from empty DIMM and PCI slots to minimize the electromagnetic interference (EMI). CPU Voltage (V)/ CPU GTL REF0 / CPU GTL REF1 / DRAM Voltage (V)/ MCH Voltage (V)/ MCH GTL REF / VTT FSB Voltage (V)/ ICH Voltage (V) These items are used to asjust the voltage of CPU, Memory, FSB and chipset. 3-25 M S-7514 M ainboard Spread Spectrum W hen the mainboard's clock generator pulses, the extreme values (spikes) of the pulses create EMI (Electromagnetic Interference). The Spread Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves. [. . . ] W hen you start installing Windows XP and older operating systems, you may encounter a message stating, "Setup could not determine the type of one or more mass storage devices installed in your system". If this is the case, then you are already in the right place and are ready to supply the driver. If this is not the case, then press F6 when prompted at the beginning of W indows setup. Press the "S" key to select "Specify Additional Device". [. . . ]
