Note: We don’t recommend you to setup your system speed to 75 or
83MHz because these frequencies are not the standard
specifications for CPU, Chipset and most of the peripherals.
Whether your system can run under 75 or 83MHz properly will
depend on your hardware configurations: CPU, SDRAM, Cards,
etc.
