Tip: When you fail to over-clock, you could:
1. Clear CMOS (JP14) to restore the default setting.
2. After turning power on, press “Home” immediately until the screen appears.

Setting CPU Frequency
i975Xz-YDG is CPU jumper-less design, you can set CPU frequency through 1MHz
stepping CPU Overclocking in the BIOS. CPU Core Frequency = CPU external
frequency x CPU Ratio. However, all CPU now selling in the market belong to
"Fixed Multiplier". That means users can not adjust the CPU Ratio but only change
CPU FSB clock to achieve overclocking.
