CPU Spread Spectrum Allows you to reduce the EMI of the front side bus by modulating the signals it generates so that the spikes are reduced to flatter curves. Disabled -0.5%, 1.0% PCIE Spread Spectrum Allows you to reduce the EMI of the PCI Express bus by modulating the signals it generates so that the spikes are reduced to flatter curves. When set to down spread, the chipset modulates the PCI Express bus baseline signal downwards by a small amount. When set to disabled, the chipset disables any modulation of the PCI Express bus baseline signal.Disabled Down Spread SATA Spread Spectrum Allows you to reduce the EMI of the SATA bus by modulating the signals it generates so that the spikes are reduced to flatter curves. When set to down spread, the chipset modulates the SATA bus baseline signal downwards by a small amount. When set to disabled, the chipset disables any modulation of the SATA bus baseline signal.Disabled Down Spread

Enabled Disabled MCP78 PCIE Training Cards supporting Gen2 mode will be trained in Gen2 mode. Gen2 if supported Only Gen1 System BIOS cacheable Enables or disables the caching of the mainboard BIOS ROM from F0000h to FFFFFh by the processor’s Level 2 cache. Disabled Enabled ParameterDescriptionOption
Chapter 217 DRAM Configuration ParameterDescriptionOption Timing Mode When set to auto mode, the system reads the electronic data sheet of the memory modules and adjusts the timings accordingly. When set to MaxMemClk, you can manually specify the memory clock frequency independent of the system bus frequency. Auto MaxMemClk Memory Clock value or Limit Displays the current memory clock frequency. CKE base power down modeAll synchronous memory devices can go into sleep mode as soon as the clock enable (CKE) signal is disasserted. In that case, the internal clocks are disabled and the memory chip goes into auto-refresh mode which is the lowest power state at which the memory retains data. If then power is turned off, the device will lose all data, however, as long as standby power is maintained, no data loss will occur. Disabled Enabled CKE based power down Sets the CKE power saving through disasserting clock enable using system level or per channel basis. Per Channel Per CS Memclock tri-stating Enables or disables the memory clock tri-stating during C3 an Alt VD feature. Disabled Memclock tri- stating during C3 and Alt VD Memory Hole Remapping Enables or disables memory remapping around the memory hole. Enabled Disabled Auto Optimize Bottom IO Allows you to auto optimize maximal memory size when kernel assigns PCI Resources.Enabled Disabled Bottom of UMA DRAM [31:24] [FC]Allows you to enter a HEX number ranging from 0000 to 00F0. Minimim 0000 Maximum 00FC
