But, because of the weakness of the fault model used and being not able to run at-speed, voltage based testing, generally speaking, is only good at verifying IC's functions.

但是，由于电压测试所使用的故障模型存在局限性，而且测试常常不能全速进行，因此一般来说，电压测试只善于验证电路的功能。

And consumption is further reduced by adjusting the operating speed and voltage of the chip on the fly, depending on the user's activity.

ECONOMIST: Transmetamorphosis

It's a less sophisticated auto-overclock, whereby three of the six cores are decelerated in order to give the other trio some extra voltage and speed for more serialized workloads.

In addition to monitoring the temperature, voltage and fan speed, the utility can also be used for overclocking and overvoltaging!
