Undervolting Information? (Z575)

2012-07-07, 1:26 AM

I've heard that the voltages for this laptop are severely high at manufacturers settings, so I want to lower them to help with cooling, performance, battery life, etc.  

 

I have no experience messing with this kind of stuff.  So far I've downloaded K10stat to adjust the voltages and prime95 to test them.  I don't understand what any of the settings mean or what I should change them too.  What should I be looking for when I test them?

 

Here's an image of the current settings and some of my hardware information:

Let me know if there's any additional information I should post.

Thanks for the link, very interesting. One thing I noticed is that overvolting is primarily used to increase performance, while undervolting is used to conserve power. Some of the people who were undervolting this laptop I've heard from said it also increased performance (perhaps it is overheating?). I don't think I'm overheating, should I even bother with undervolting?

These are my settings:

Don't pay attention on frequency in CoreTemp, it is wrong :D

Now, these are my settings with undervolted and overclocked proccesor:

Why dont you use "overdrive" from amd? With overdrive you can increase the core speed up to 2400Mhz without K10stat ... K10stat causing bluescreens like hell...
