System Memory Multiplier (SPD) Allows you to set the system memory multiplier. Auto sets memory multiplier according to memory SPD data. (Default: Auto) Memory Frequency(Mhz) The first memory frequency value is the normal operating frequency of the memory being used; the second is the memory frequency that is automatically adjusted according to the BCLK Frequency(Mhz) and System Memory Multiplier settings. PCI Express Frequency(Mhz) Allows you to manually set the PCIe clock frequency. The adjustable range is from 90 MHz to 150 MHz. Auto sets the PCIe clock frequency to standard 100 MHz. (Default: Auto) >>>>> Advanced Clock Control CPU Clock Drive Allows you to adjust the amplitude of the CPU and the Chipset clock. Options are: 700mV, 800mV (default), 900mV, 1000mV. PCI Express Clock Drive Allows you to adjust the amplitude of the PCI Express and Chipset clock. Options are: 700mV, 800mV, 900mV (default), 1000mV. CPU Clock Skew Allows you to set the CPU clock prior to the Chipset clock. Options are: 0ps~750ps.
