« Note: We don’t recommend you to set up your system speed to 75, 83,
112, 124, 140, 150 MHz because these frequencies are not the
standard specifications for CPU, Chipset and most of the
peripherals. Whether your system can run under 75, 83, 112, 124,
140, 150 MHz properly will depend on your hardware
configurations: CPU, SDRAM, Cards, etc.
