Frequency Settings

qCPU Freq, MHz

This value is set by the CPU Multiplier (value cannot be changed by the user).

qFSB 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.

qCPU 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.

qPCIe x16_1, 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). Note that as you go higher in value, PCIe Spread Spectrum(SPP) is disabled and cannot be changed from this status.

qPCIe 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).

qPCIe x16_2, MHz

Use the Page Up and Page Down keys to scroll through the frequency options for the PCI Express Bus, Slot 3 (the black slot farthest from the CPU).

qSPP<>MCP 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.
