 CPU Freq, MHz This value is set by the CPU Multiplier (value cannot be changed by the user).  FSB Reference Clock. MHz This value is set by the system (value cannot be changed by the user). To change the SLI-Ready memory, FSB memory, and memory timing, go to the FSB & Memory screen.  CPU Multiplier This value changes the CPU Frequency value depending on the value you choose. Use the Page Up and Page Down keys to scroll through the options. The options are from 6 X through 60 X.  PCIe x16_1, MHz & PCIe x16_2, MHz Use the Page Up and Page Down keys to scroll through the frequency options for the PCI Express Bus, Slot 1 (the black slot closest to the CPU) and Slot 2 (the black slot farthest from the CPU). Note that as you go higher in value, PCIe Spread Spectrum(SPP) is disabled and cannot be changed from this status.  PCIe x16_3, MHz Use the Page Up and Page Down keys to scroll through the frequency options for the PCI Express Bus, Slot 3 (the blue slot in the middle).  SPPMCP Ref Clock, MHz Use the Page Up and Page Down keys to scroll through the frequency options for the reference clock between the SPP chip and the MCP chip.  nForce SPP - -> nForce MCP Use the Page Up and Page Down keys to scroll through the HT multiplier options and set the link speed from the SPP chip to the MCP chip. Values are [1 x] through [5 x].  nForce MCP
