What does undervolting do??

Ok besides lower temp's of the laptop, what specifically does it do? Does it also lower processor speed? Lower performance of the laptop? And how would one go about this?

 

Clocks the processor speed to 800mhz~ or so. Which reduces heat created.

This lowers the performance of the laptop, but if you are surfing, word processing, watching movies, etc. 800mhz is speedy.

I wrote a small buzz about undervolting, check the ASUS FAQ.

 

thanks corolis i followed your step by step and it lowered my temp from 72 to 57. Now my question is, with dynamc switching it will automatically switch to 2.0GHZ when i start up a game right?? And would u say 57 is now normal temp with dynamic switching on or should i still get my laptop checked by the computer store i bought it at becauswe of the previously high 72 temp with no dynamic switching tunred on.

 

Yea, it will automatically clock up to your max clock speed.

57 for what part? The GPU?

 

no 57 for the cpu while browsing the interenet

 

How are the fans? How fast rather?

 

Undervolting doesnt lower the processor speed. It maintains the same frequency but just lowers the voltage used to operate at that frequency.

This works because when chips are manufactured there is some random variance in their quaility. Consequently, some chips would be able to operate at say 2.0 ghz for example on less voltage than others. However, because it would take far too long to alter the voltage on each chip, the manufacturer chooses a very conservative voltage under which all chips will surely operate. This means that some chips, in fact most chips have potential to operate under much lower voltages at the same frequency.

There are a couple of programs that you can use to undervolt, Rightmark clock and centrino hardware control are the most popular ones. Undervolting does not decrease your performance and it does not lower your processor speed. It does, however, increase battery life by around 20 mins and lowers your processor temp by around 10 degrees celcius.

 

right now i have it so that speedfan automatically adjusts the fans. At a temp of 57 fan is currently 860RPM

 

Errr, got confused there. ray is right, I keep getting undervolting for CPU and underclocking for GPU's confused.

My bad!

 

so am i ok CPU temp before dynamic switching while browsing the internet was 72 now after dynamic switching it is 57. Should i take it to get it looked at by the place i bought it cause the temps higher then it should be or is it fine??

 

57 degrees C while browsing is not bad, it may be a little on the warm side but nothing abnormal.

 

Aside from what was mentioned it will also make your notebook unstable. It all depends though. Not everyone will experience instability.

 

if undervolting makes your system unstable, you need to undervolt less.

 

There is a bit of trial and error involved, but all the undervolting problems I've read in the forums have been caused by folks using voltages that were too low. This can easily be fixed by bumping the voltages up a few notches to where it's stable.

However, as Eddie pointed out, undervolting isn't necessary, and if you're uncomfortable doing it, don't. It's that simple!
