CPU Host Frequency (Mhz) Allows you to manually set the CPU host frequency. The adjustable range is from 100 MHz to 1200 MHz. This item is configurable only if the CPU Host Clock Control option is enabled. Important: It is highly recommended that the CPU frequency be set in accordance with the CPU specifications. 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.
