[. . . ] They are read only. 3-22 BIOS Setup FSB/DRAM Ratio This item will allow you to adjust the FSB/Ratio of the memory. Adjusted DRAM Frequency (MHz) It shows the adjusted DDR Memory frequency. ClockGen Tuner Press <Enter> to enter the sub-menu and the following screen appears. 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. They can help CPU to reach the higher overclocking performace. Adjust PCI Frequency (MHz) This field allows you to select the PCI frequency (in MHz). Auto Disable DIM M/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)/ DDR_VREF_CA_A/ DDR_VREF_CA_B/ DDR_VREF_DA_A/ DDR_VREF_DA_B/ MCH Voltage (V)/ MCH GTL REF/ VTT FSB Voltage/ ICH Voltage (V) These items dispaly the power status of CPU, Memory, FSB and chipset. Spread Spectrum W hen the motherboard'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. If you do not have any EMI problem, leave the setting at Disabled for optimal system stability and performance. But if you are plagued by EMI, set to Enabled for EMI reduction. Remember to disable Spread Spectrum if you are overclocking because even a slight jitter can introduce a temporary boost in clock speed which may just cause your overclocked processor to lock up. 3-23 M S-7516 M ainboard Important 1. If you do not have any EMI problem, leave the setting at [Disabled] for optimal system stability and performance. But if you are plagued by EMI, select the value of Spread Spectrum for EMI reduction. The greater the Spread Spectrum value is, the greater the EMI is reduced, and the system will become less stable. For the most suitable Spread Spectrum value, please consult your local EMI regulation. Remember to disable Spread Spectrum if you are overclocking because even a slight jitter can introduce a temporary boost in clock speed which may just cause your overclocked processor to lock up. 3-24 BIOS Setup CPU and Memory Clock Overclocking The D. O. T Control, Adjust CPU FSB Frequency, Adjust CPU Ratio, FSB/Memory Ratio are the items for you to overclock the CPU and the Memory. Please refer to the descriptions of these fields for more information. Important 1. CPU Speed = CPU Frequency * CPU Ratio 2. This motherboard supports overclocking greatly. However, please make sure your peripherals and components are bearable for some special s ettings . [. . . ] From W indows Vista/XP, open the Control Panel from My Computer followed by the System icon. Choose the Hardware tab, then click the Device M anager tab. Click the "+" in front of the SCSI and RAID Controllers hardware type. The driver JMicron JM B36X Controller should appear. D-12 JMicron RAID JMicron Raid Configurer There is an application called JMRaidTool which helps you perform the following tasks of JMicron RAID. [. . . ]
