处在睿频状态时,即p0状态,而且p0又随着频率的继续提升,每100Mhz一个阶梯的从p0-1一直提升到p0-n,p0n即最大的Max turbo frequency最高频Pmax。另外一边,CPU还有空闲主动降低功耗的speedstep动态节能技术,对应的就是p2～pn状态,也是按照100Mhz的阶梯,n逐渐+1直到系统约束的最低频率(一般是800MHz,少数1GHz)。有几...

Finally, there’s the option of setting voltage and frequency on your own, but we don’t suggest it as these other methods will likely work just as effectively. If not, you’ll need to do small decrements on these values and repeated testing until you find that sweet spot. For a more...
