CPU-Z for Dummies

Hi,

I did a CPU-z on my D820 with a t7200. It said it had a core speed of 999 MHz. It said the voltage was around .9.

I was wondering why, and I did some research to see if I could figure out why it said that. Then I did the test again, and now it says 1995 MHz.

Why did it say 99x before? Is it because the voltage was lower? If so, why was the voltage lower?

Thanks!

 

i am not sure if this is the correct answer but maybe the prossecor slowed it self down to conserve battery life or the laptop manufacture has some program running in the background.

 

I think that your processor was idling and clocked itself lower to save on power. When it does that the voltage also goes down. This is a feature that is found on most if not all modern mobile processors.

An analogy will be when your car is idling, the engine runs at around 800 rpm. This is because that is the amount of power you need to keep the car running. However, when you step on the gas, the engine responds accordingly. Rpm goes up as well as fuel used. So its similar, just think of the CPU as the engine and the voltage as the fuel.

 

Hi,

Thanks for the reply.

The computer was plugged in, so I hope it wasn't slowing itself down for some reason.

I did notice that the multiplication factor (I think thats what it was called) was 6 vs. 12 now.

What are the reasons that it would do that?

Thanks

Jeff

 

Speed step was on before which slows the processor down when all the power isnt needed. It saves battery life.

 

You just switch your power management to desktop or unmanagement mode, then you will see the full speed. Remember to change it back after you saw the happy score, that mode will eat up your battery.

 

Intel SpeedStep and AMD PowerNow! are features found on mobile chips that help conserve battery life. It reduces the CPU clock multiplier by undervolting it to lower the power consumption and heat.

 

Is there any way to bypass that besides by doing it indirectly via the power settings?
