自由超频：Core i7-875K/i5-655K实测

默认电压下，从原始频率3.33GHz提高到3.77GHz只多消耗了4W；想突破4GHz就得稍微加点儿电压，但功耗也不过多出7W；再往后就比较糟糕了，每走一步都得付出很大的功耗代价，最后达到4.127GHz的时候电压加至1.225V，此时功耗突破70W，核心温度也升至77℃。

不过仍然要比i3-540好多了，后者在3.8-3.9GHz区间内温度和功耗都大幅增加。

换上水冷就好多了，4.25GHz的时候才消耗70W，温度才不过47℃，最后超至4.5GHz，消耗91W，但温度只有61℃。

i5-655K、i5-661、i3-540的功耗/电压曲线很是纠结，说明它们的功耗随电压上升的情况基本差不多。
