Intel Speedstep technology?

[Iron Knickers]

Instead of using an offset or adaptive mode to dial down my CPU voltages when I overclock, could I instead just input a manual voltage and enable speedstep to automatically dial down the voltage and clock speeds when idle?

Yes in theory, but it may not be as accurate. I haven't experimented with it.

Let the C-States enabled as well and it should downclock when idling, but it won't undervolt.

 

Not that it matters, though, your CPU should never be idle anyway.

Isn't your CPU on idle when you aren't doing anything though?

Not at all:

(It went up to 29days before I had to shut it down.)

 

As I said, you should never have your CPU idling. Instead of letting your compute power go to waste when you aren't using it, have your CPU crunch stuff for researchers all over the world that need this sort of processing power.

This depends on the generation of cpu. But it is taken care of for you. Also yes folding is good. But it will cost power and money as a result. Your cpu is idle but there are different types of idle. Which you can think of like speedstep. 

 

Volts dont matter. As long as freq is lower your fine with regards to power.

Wow dang I've seen stuff like this, maybe ill look into helping cure cancer.

If you're pumping lots of volts into your CPU even with lower frequencies doesn't this wear down the cpu and create a lot of heat though?

Volts matter a great deal, as you increase voltage power consumption gets exponentially higher and therefore heat and noise.

As I said with reguards to power it is both. Not pure volts. It has more to do with the transistor flipping. You need more volts to drive a higher clock speed in order to get transistors to flip faster. But if they are not flipping often that means less power is required to flip. I suppose it is a combination of volts and frequency. But if your frequency is 0, the power is close to 0. That does not mean you wont kill things by using a silly high voltage to flip them. And it will use more power if you force the higher voltage. But, it is not pure volts. As for op question, I would let the cpu do the power states.
